Lyons Plumbing

Can't say enough good things about Lyons Plumbing! We just bought a house in Hyattsville, and immediately had a problem with our basement bathroom. The first company we called came out, charged us $2900 for an escalating series of fixes, and failed to fix the problem. Not only that, but they wanted $5300 to dig up our yard in yet another fix attempt!

We decided to get a second opinion, and thank God we did. We reached out to Lyons through Yelp and were soon on the phone with Dan Lyons, the owner. He was good-humored and knowledgable, he took the time to understand our problem, and we were immediately at ease. Next morning, he sent out Kevin & Brad, who *actually* fixed the issue for just $500. Kevin thought there was an issue with our sewage ejection pump, so Dan sent out another employee the next day--but it turns out there wasn't a problem, and they didn't charge us for the visit.

Lyons Plumbing turned our nightmare plumbing issue into a nothingburger. Everyone we dealt with was knowledgeable, friendly, and honest. I wish we'd called Lyons Plumbing first! Lesson learned. Next time, we definitely will.

We had a shower faucet installed incorrectly by another contractor. It was apparently a newer type of valve and they didn't know how to put it in right. Mark from Lyons plumbing came in and was able to reinstall it correctly and get it working 100%!! He is a genius!!!!! We thought we would have to get a completely new shower system! Lyons was very fast, efficient, knowledgeable, and reasonably priced!  I would give 10 stars if I could I am so happy!!!

I needed a main water valve, along with other various items and Lyons Plumbing was very professional and responsive. I was able to get the issue fixed very quickly. Mark did an excellent job and even pointed out other items that needed attention (electrical items). He replaced everything with high quality materials and even helped me with my water pressure that I've been complaining about for years! Thanks Mark, Dan, and Lyons Plumbing!

A friend of mine had to hire a plumber recently in another state and ended up having to do the work all over himself.

I'm very grateful that Lyons Plumbing knows what they are doing!

We hired Lyons Plumbing to have our whole house re-piped (we had polybutylene pipes). Dan Lyons and his team were very professional and responsive during the entire process. They were able to come over on Saturday to give us a quote (we also reached out to other companies and they all need to wait til Monday to come over and provide a quote). The work quality is very good. The plumbers are very friendly. We're happy that we find Lyons Plumbing and will definitely use them again if we have other plumbing issues in the future.

Big shout out to Dan and Mark for allowing me to check one item of my Honey Dew List! I looked up Plumbers on Friday and received multiple quotes. Ultimately Dan's responsiveness and clarifying questions to fully understand the job at hand, made me comfortable to move ahead with the scheduled appointment on Monday.

Mark, the plumber who arrived to perform the job, came earlier than expected, which I had no problem. He came to the door with his mask on, and I met him at the rear of my house. I previously cleaned out the cabinet so Mark could have the best, as possible, area to work with.

My original faucet came with the house when I bought it. Between my kids and wife's need to turn the faucet on at full blast each time of use, water was leaking below causing rust and corrosion on the connections. Mark, said, This is going to be difficult. He walked out to his truck, came back to saw off the original faucet, and the new faucet was on in what felt like 15 minutes.

Mark informed me the hand soap dispenser that came with my faucet could not be out on because my dishwasher is taking up the last hole on my sink. No worries, we didn't use it anyways. I won't be getting a new dishwasher until the kitchen is funny renovated.

Dan and Mark will be the first ones I call for the next project.

Lynn's Plumbing gets an 11 out of 10 review. Yep, they are that good.  They extremely reasonable, extremely professional, and beyond competent. My plumbing professional for life. Dan the owner is unlike any other company owner. He is an owner and a worker. Very, very knowledgeable and polite to the customer and his staff.  Give these guys your business.

Excellent service from start to finish, came in with the best quote and were professional at every interaction.

On-time, quickly assessed the issue, fixed it in less than 30 minutes, paid with a CC, and they take a check too.

My go-to for all future needs. Thank you Dan and the fastest plumber Mark!

Did an emergency, same-day main line snake for us.    Competitive pricing and competent technicians.  Through a follow-up camera inspection, they seem to have fixed what multiple companies had previously missed.

Will hire again.

We had a great experience with Lyons Plumbing.  Dan was so quick to respond and remained very responsive throughout the whole process.  They were able to squeeze in our big job pretty quickly, and offered some great advice on what we could do until everything was working properly again.  Fortunately, the job was finished even quicker than we anticipated.  The whole team that came out was awesome!  I highly recommend them.

I had a plumbing issues last night on a Thursday afternoon that I needed done by today (Friday) so my Tenants could move in. When I say quick and responsive is an understatement for Lyons Plumbing! They answered on the first dial, called me with 2 hours to schedule me for the next day, called me when he was on the way AMAZING service. He was in and out so quickly but addressed all my concerns and explained to me the issues and on top of that FRIENDLY! highly recommend, they will be my go to plumbers from now on.

Lyon's Plumbing is great and I would highly recommend them to others in the MoCo area. They responded to my emergency inquiry immediately on Yelp and came out to my parent's house at a convenient time that worked for us. They sent over their plumber, Mark, who was punctual and communicative throughout the whole process. He gave an ETA before he arrived at the house and resolved all the issues quickly/thoroughly. The pricing is fair and the customer service is excellent!

We called Lyons after hours to fix a leak in one of our bathrooms, and our appt. was scheduled for the next morning. After the inspection we needed repairs in both of our bathrooms, and this was resolved in about an hour.   The person that repaired our toilets explained everything he was doing and gave us recommendations on how to maintain these repairs. Overall the service was great and we recommend Lyons.

I'm giving them 4 stars bc the service was almost $500 to fix 2 toilets. One toilet needed a major repair including replacing all the parts inside the tank, replacing the screws and resealing. The other toilet needed replacing that chain thing inside the tank. I don't know if these are industry standard prices for this service.

I contacted Lyons plumbing because my water pressure was not building from my well pump. The gentlemen who came worked quickly to tell me my well pump and tank were defective. It would cost me close to $5000 to replace both ($1500 for the tank, $3000 for the well pump replacement)

I called another company who quoted me $3000 to do both. The gentlemen who came out, diagnosed my system, and told me my tank and pump were both fine and that it was likely a check valve that was bad. He pulled out the pump and showed me that indeed the check valve was bad and that he would charge me $400 total to repair it. I went ahead and had him replace the pump since it was 12 years old anyways.

Everybody makes mistakes, and Lyons company was nice. I dont think they were actively trying to deceive me. However I think the Yelp description for 2 stars is appropriate... Cloud've been better.

I found Lyons Plumbing after getting tired of an annoying leak in my bathtub faucet. They came out and replaced the faucet set with a new one I bought, and, like magic, it stopped the leak!

After talking to the team I feel that they were honest and trustworthy. I arranged with them to do bigger jobs in the future when I save up for them. I am happy to say I have a plumber now!

Mark just finished installing our new dishwasher and we couldn't be happier! He was friendly, efficient, and answered all of our questions. Thank you Mark! We'll be calling you back for our future plumbing needs!

I had a leak coming from my shower into my living room. I went through Yelp and found a couple of businesses including this one. The owner was very responsive and communicative. I scheduled an appointment and the plumber arrived on time and was very pleasant.

He had mentioned to us that there would be an additional fee for him to try to find where the leak was coming from. We explained to him that we knew where the leak was coming from but he completely dismissed that and said that he would need to do a leak test. We agreed and paid the additional money.

I'm not really sure what he did but he ended up telling us that the floor in our bathroom was rotted underneath. He said that we would need to contact a general contractor and have the entire bathroom floor lifted.

He did some minor caulking around the shower exterior door. We ended up paying $225 for the visit/service.

The very next day the pipe was leaking again so we contacted a family friend who is also a plumber and was in town visiting. He cut a hole in the ceiling and confirmed (what we had originally thought), the leak was from the bathroom shower and showed us the exact leakage from the pipe.
He said for a quick fix we could go to Home Depot/Lowes and purchase Flex Seal. We did that the same day and the leak stopped.

A few weeks later the pipe started leaking from another spot. We contacted another plumber in the area and they came out the very next day. When I scheduled the appointment they were very upfront with their cost and what the cost would entail.

This other company came out and was able to fix the problem same day only charging us $160 total.

I would not recommend Lyons plumbing. As other people have stated, I think they are just money hungry. I don't feel that the $225 we paid was realistic or fair for what we received.

My family has been using Lyons & Sons Plumbing since the 1970s. They have always been reliable, offered fair rates on their work, and friendly. Just this week, I had a number of plumbing repairs that needed to be done in my home, including diagnosing a leak in my master bath shower. I was surprised that they were able to schedule an appointment for the next day (most contractors are so busy these days). They arrived within the time frame given, and Mark was very thorough in the work he did. He needed to purchase a couple parts to finish the repairs, and was able to come out the following day, again, within the time frame given, and finish the repairs. I am 100% pleased with their work - even after 50+ years!

Great experience overall - highly recommended. Dan was super responsive and helped me troubleshoot the issue with the sump pump up front. Later on he was very quick to provide a complete quote for the job. Mark was here today, arrived on time in the 2 hr window provided including giving me a 30 min heads up. He did a great job getting the old unit out and new one in with no issues whatsoever. Will def call them again!

Our shower hardware broke and a clogged sewer line flooded the bathroom in the same week. Dan and his crew at Lyons were very responsive. They came out twice to fix the shower and bathtub and again for the clogged sewer line. Haven't had any problems since. Happy with the water pressure in the new shower as well.  I'll definitely use them again.

Called for a leak in a bathtub faucet.  Turns out it was a very old model of faucet that required cartridges.  The plumber who responded only had 1 cartridge in the truck, but recommending replacing both (one for hot water, one for cold).

Unfortunately, because he only had one cartridge in the truck, it would be another $200+ service call if we wanted to proactively replace the 2nd cartridge.

I'm happy with the service provided, but what would have earned a 5 star review is if the plumber offered to get the missing part from a hardware store and come back and install it.  I'd be willing to pay a little extra for that, but a whole additional $200+ service fee seemed excessive.

Our toilets weren't flushing and all our drains were backed up. Within a few hours our drains were unclogged and out toilets were flushing like they were new. All services were done on the same day and handled efficiently and professionally.

Mark and Don were quick in their response with our plumbing issue. They get right to the point in resolution and even came back to fix another issue for free. Love their service and would recommend them

We noticed that a leaky faucet in an upstairs tub was leading to watermarks on our kitchen ceiling and were able to guess there was an issue with the cartridge in the faucet. After watching a few YouTube videos about DIY cartridge replacement, had a gut feeling I should reach out to a professional. Made a request on Sunday and had Mark out to take a look at the issue Tuesday morning. It turned out to be a great call as the cartridge, which might've never been replaced before, broke off when trying to pull it out. Luckily, Mark was unphased and went above and beyond to clear it out and get the cartridge replaced, leaving everything better than when we got the house, in under an hour. Hopefully we won't be needing any plumbing services again anytime soon, but if we do Lyons Plumbing will absolutely be our firsts call.

Kevin was terrific. Extremely responsive, thorough, and knowledgeable.  He sealed a leaking toilet that another company wrongly diagnosed as a problem with the mainline.

Dan was quick to respond to my Yelp quote request on the day after July 4th, a Sunday. The water heater in my rental house had sprung a leak and made a big mess right when my poor tenants were moving in. The quote was in line with other numbers I was offered and he could get to the work on Monday so I scheduled with him then.

He and his crew showed up in the agreed upon window, unfortunately I was in the basement and didn't hear them knocking, but once I let them in it was a quick diagnosis, some draining and hauling out the old tank. In came the new tank and an up-to-code gas shut off was installed too. They all appeared competent and were professional throughout the job. The price was exactly as quoted. I would definitely hire them again.

Lyons Plumbing was reasonably priced and completed my job in a competent and professional manner. I will be using them for all my plumbing needs.

Imagine having your worst nightmare come true: a contractor that walks off a job and leaves you with a busted shower system that doesn't work and you have nowhere to turn. I had three plumbers come to our house who refused to do the work to finish off our home renovation and was getting anxious.  Enter Lyons Plumbing, who saved the day!

For starters, Mark B.--the world's BEST plumber--walked into our bathroom and took one look at the system that the contractor left and said HOW did they do this--it's not up to code. They installed a new shower system on your external wall and knowingly didn't put in insulation!  These were not professionals!  Mark and Dan proposed a proper fix, which meant we had to take down the tile and move our shower plumbing BACK to its original position.  Lyons partnered with Watson Squared Interiors, our tile team, to get rid of the faulty system and helped us land on a new tower system that exceeds our needs.  

From start to finish, Dan Lyons and Mark B. explained what needed to be done and made sure they were here to complete their portion of the install.  Dan went the extra mile to document the issues for us as I'm taking the other contractors to court.  His write up will help us recoup the losses!  Mark B. worked his magic on site and the shower now runs without issues and works great.

Dan and Mark represent the best on home contractors.  They're trustworthy, reasonable, honest and personable--everything the other vendor was not!  I can't think of calling anyone else from now on when I have a plumbing issue.

There are bad plumbers, there are good plumbers and then there are superheroes like Lyons Plumbing.  Hire them--they are nothing short of terrific!

I needed a plumber for a new leak I had. I contacted Lyons Plumbing and they replied quickly. I was able to give a brief description of problem and they said they could repair. They were very quick and responsive to all my questions and especially very professional.

I was informed that the leak was from an old faucet and the brand would send a replacement. Again Lyons Plumbing informed me of this. How honest is that, not trying to sell a part. I cannot day enough on how great they are.

When they came to work on the leak they were on time. A quick review of the issue was discussed. The issue was resolved and part was installed. They noticed another issue and resolved that by replacing the catch inside of the sink which had been worn out and leaking as well.

In all this company is honest and professional. I recommend them to anyone looking to have a plumbing job done.

Lyons plumbing did an excellent job at my place. Dave and Kevin are some of the nicest and honest people I have ever seen.
They not only fixed the sewage backup but also advised me to work with my builder to make sure the problem is covered by the warranty.
I will recommend Lyons plumbing without any hesitation.

I had a backup in my kitchen sink drain and needed it snaked. I called multiple plumbers first thing Monday morning and they were either 1. Not available the same day, or 2. Beat around the bush regarding an estimate to snake the drain pipe. Lyons Plumbing was able to fit me in the same day and provided a competitive estimate over the phone.  

Being a snowy day, Lyons Plumbing planned to have all their trucks off the roads by 5pm, but the tech, Kevin Lyons, fit me in at 6pm as the last stop of his day. He was incredibly professional, unclogged the pipe quickly, and cleaned up after the repair.

I had a great experience with Lyons Plumbing and highly recommend them!

Professional, courteous, and reasonably priced. I did not actually receive service from Lyons Plumbing, but during my quote request process, Dan the owner, was very forthright and responsive. The quote he provided was one of the more affordable ones as well as well explained.

Had an issue with my PRV little bit misunderstanding of the scope of working, temp fix made going to see if it holds out

I had a leak from the bathtub and I determined it's the joint between the drain opening and the pipe, but I don't have the tool to fix it myself. Upon responding to my Yelp request on July 4th, Dan looked at the pictures I sent him and patiently listened to me. After much discussion he would let me order a part from Amazon at half the price from the plumbing supply house.

Today his guy Mark showed up and got the job done in less than half an hour, with great efficiency and thoroughness. Shall I also say the price was very reasonable? I really appreciate Dan's honesty and professionalism. I would recommend Lyon's to my friends around the area.

Estimate of $500 to extend outdoor facet. Guy installed on house charged $750. Getting another plumber to replace with copper. good looking plastic.

Lyons Plumbing just wrapped up getting my main waterline valves unstuck and replacing one of them entirely.  I called less than 24 hours beforehand and was extremely impressed with the quick turn around.  Pricing was upfront and fair.  Our plumber, Mark, had the replacement done in no time, even though my father-in-law and son were bothering him during the valve install.  Excellent service, fast response time, and fair pricing... what more could you ask for?  If you are looking for a plumber in the Damascus area, definitely give these folks a call!

No games, just great work!! Got a quote with in minutes. Mark came and did an excellent job in minutes. He was very professional and friendly. I would highly recommend using Lyson's service. Thank you Mark for your work!!

After closing my business to work from home to have a garbage disposal installed, the first handyman was unable to complete the work due to the placement of the pipes. He charged me $79 for showing up and boot scooted on out the door. Back to yelp...sent requests to a few different plumbers. Settled on Lyons plumbing, #1 becaise of the stellar reviews,  #2 Dan Lyons had one of those honest trustworthy faces, #3 it was located on Damascus, and Damascus people are the nicest people in super pretentious MoCo. They were beyond full with jobs and fit me in at the end of the day. Praise Jesus! Repairman Mark was in and out in 20 minutes. I am so happy! Thank you Dan and all at Lyons Plumbing. Such a class act!

We contacted Lyons 2 days before we needed our kitchen plumbing (sink/faucet/garbage disposal) reconnected after new countertops/sink would be installed. They took the time to educate us about our service needs and gave us an accurate estimate for the job. They were very knowledgeable and explained what needed to be done regarding moving our pipes down (due to the new sink being much deeper than the old one). The plumber who came out was very professional and completed the work quickly.  Excellent communication from start to finish.  We are very happy with the level of service we received.  COVID precautions were taken.  We would definitely use them again.  Highly recommended.

Lyons Plumbing handled an emergency sewage backup in my basement toilet. Work was great , very efficient and explained everything very well.  PRICE was reasonable. Techs were friendly and very easy to talk to.  Also , quite funny at times.   Enjoyed some much needed  laughs. Would definitely recommend and will be using them again.

They're the best at what they do.  The price was a fixed price, quoted based on the description (clear kitchen drain pipe) and very reasonable.  They cleared the line quickly and efficiently and gave me a few tips to help keep the kitchen drain from clogging again in the future.  They even increased the water flow so that the drain would naturally clear better.  Highly recommend.

We had a  'handyman' do some work.  We ended up with out water to our master shower.  I called on Thursday Afternoon and Dan called me back with an appointment for the perfect time on Friday morning.   Mark called 1/2 hr away and the 2min away giving us the opportunity to secure our pets.    Mark wore a mask and Quickly corrected the error.   We are so appreciative.    Lyons Plumbing is our Go To company when plumbing services are needed.  Thank You

Moved in to a new house and discovered the toilet was wobbly and leaking within the first day or so.  Actually posted a plumbing request on Yelp to another plumbing service, but Lyons responded first, and after checking their reviews decided to go with them.  Mark, one of their master plumbers, came out the next day, identified the problem, and fixed it for us in about 30 minutes, as well as gave us some general plumbing advice.  We're very happy with the professionalism and quality of Lyons plumbing, and they will be our go-to for all our future plumbing needs.  Thanks, Mark!

Great company! I needed to have a plumber come out on an emergency basis to help with some remodeling work I was getting done and they had a plumber (Mark!) at my home within 30 mins. Mark was professional, courteous and did an excellent job! Highly recommend and will definitely use them for future plumbing services.

We had to have three toilets replaced and we'd reached out to get a quote since we had a much higher quote from another company. Dan was extremely helpful in explaining and breaking down the charges for us. This helped us make a good decision as we were well-informed. The technician they sent was absolutely fantastic (and careful as he wore a mask throughout) and the job was done super well. We now have three new toilets installed and working perfectly! I'd definitely recommend Lyons Plumbing.

This contractor was great in a lot of key areas; specifically: responsiveness to Yelp quotes, flexibility and expedited service, reasonable pricing and rock solid technicians.  

Mark, our service provider was particularly helpful in resolving our water pressure and water temperature predicament; leveraging over 20 years of experience to address our problems during a brief visit WITHOUT up-selling unnecessary and costly system add-ons.  Results: Desired water pressure and water temperature...and a happy wife (happy life).

During our visit, Lyon's pluming also took time to listen to a secondary concern (hot water capacity) and when requested provided estimates for labor and equipment which will meet our families needs.  They did not apply sales pressure; just answers that I needed to plan my next project.

Bottom line:  Great firm, great experience.  They earned a repeat customer with me!

One of my toilets was clogged - plunging wasn't working, chemicals didn't work, so after a Yelp search, I called Lyons.
My original appointment for Saturday had to be rescheduled because their truck was in the shop and repairs were taking longer than expected.  I was told that they would be at my house by early afternoon, Sunday.  
While they didn't show up until about 4, they were very apologetic.  
And Kevin is just hilarious!    
They were finished in about 15 minutes and Kevin even took the time to clean up any mess and make sure that everything was tidy when he finished.
In all honesty and being fair, I would have taken off one star because they were late, but they were so very friendly and efficient, that I gave them the star back.
I would recommend Lyons to anyone looking for plumbing service.  I hope I don't have a need to call them again - no one likes to deal with home repairs/expenses, but if I do, I will call Lyons.

The best! I needed a new disposal and toilet. Everything from estimate (more value than another quote), scheduling and installation was simply a breeze.

Highly recommend.

I was able to quickly get a quote to repair a leaking sink that another company failed to fix.  After accepting their quote I was able to be scheduled for the next day.  They were able to explain to me the cause of the leak and how they had fixed it, making me feel confident that the work was done correctly.  I would definitely hire them again.

Couldn't be happier with the service we received! Mark came on time and repaired the problem. He said if it wasn't right to call and they would come back and only charge for any additional parts necessary. I called the next day because there was still a small drip. He returned with another helper and they fixed the problem for no additional charge. I highly recommend this company!!!!

Really kind and took the time to listen and understand the problem and went out of their way to help fix a gas leak. Would highly recommend!

Mark quickly diagnosed my gas leak, fixed it, turned on the gas line and tested it. He was done quickly, efficiently and explained every step. True a professional. The owner Dan then spent an hour on hold w my home warranty company so I could submit a claim. They were both great. Would definitely use again

I am a new homeowner and I've had to call on Lyons a few times for projects around the house.  Very reliable, friendly and immediately responsive  to any questions.  I will be keeping them as my go to plumbers for sure.

Found Lyons Plumbing on yelp and called them went my hot water heater stopped working. They quickly came out the next morning and replaced it the following day.  Dan went above and beyond to do research to find the perfect fit replacement to eliminate some possible extra costs with the venting. I highly recommend Lyons Plumbing and will definitely use them again.

I send a request message for a service  on yelp and Lyons plumbing was so swift with answers and were readily available to come over to access the issue. Mind you i sent the request on Saturday.

Good service is hard to find these days, let alone great service. However, that's exactly what I received when I reached out to Lyons Plumbing.  The service was outstanding and my issue was resolved at a reasonable price.  I found Dan, the owner, to be very responsive.  And Mark, the tech, knew exactly how to fix the issue in my bathroom and was able to resolve it in about an hour.  I now know that I'll be using them for any plumbing issue I run into in the future.  I would highly recommend Lyons Plumbing to anyone that needs a reliable, trustworthy company to address any of their plumbing needs, without overcharging.

During the initial phone call Dan asked a few basic questions to understand the issue and scheduling was done in matter of minutes. Mark arrived a few minutes ahead of schedule.  I had an issue with cold water pressure with the basement shower faucet. The hot water side was just fine. Mark checked the cartridge and found that there was no issue there. There were no obvious answers. This is typically where most people give up or look for excuses. He methodically checked water pressure at various points in the cold water line (sink faucets, toilet inlet etc.) and narrowed his examination to a small section of the piping and made a couple of strategic cuts. Lo and behold we saw that stuck near the T section of the piping was a small plastic ball. While we could not determine where that obstruction came from, removing it completely fixed the problem. Efficient work done systematically and professionally is what you get with Lyons Plumbing. Recommend without reservations.

I needed my drain snaked.  They came out quickly and did a great job and their price was very reasonable.  Very nice and professional.  I will definitely use them again!!

The valves to our washing machine were leaking in a very big way - created a big mess - Lyons was great. They jumped on FaceTime with us, diagnosed the problem and were out in a short period of time on a Saturday afternoon to help us.  Can't say enough good things about how happy we were with their service, responsiveness, and just plain great customer service. I wholeheartedly recommend them and they will be our plumber going forward.

A+++ all the way. Had a clogged kitchen sink and contacted Don. Within minutes he wrote back with price and said he would send someone out later that day. Kevin arrived mid day with positive, can-do attitude, quickly snaked drain, and checked out everything, cleaned up and was on his way. Same price I was quoted, which was less than I found with others. They were responsive, polite, on time and speedy. Said they would come back if any problems when I ran dishwasher. No problems at all, everything works great. Thank you Lyons Plumbing, highly recommend.

Excellent!!  Steve is the best!!
Magnolia Plumbing came out the day before with an estimate of $2000 to replace 3 valves.
I called Stephen that afternoon & he came the next morning.  Said the replacement was totally unnecessary.  Leak was only in one valve, and that could be repaired - no replacement.  Stephen successfully repaired the valve - took 10 minutes.
He also diagnosed an issue with our leaking dishwasher.  Until I can get an appliance repairman out, Stephen capped the garbage disposal so we can use the kitchen sink.
And he diagnosed an issue with our shower faucets.  Told me how to order warranty parts - and then he can fix.
All this took less than 1 hour!  Cost $175 - not $2000.

Realized my kitchen faucet had a leak when I went under the cabinet.   Water running free and your house don't mix well!   I went right to Yelp! to do the standard operation of putting out word to 4-5 well-reviewed plumbers and see what I could get.  Lyons Plumbing got back to me quickly.  Dan Lyons got on the phone and we talked through the issue.  He's the owner - not an office scheduler - so an immediate, productive conversation (unlike with a lot of the big companies).  Sent a couple pictures and a description of what was going on, then was able to have a faucet ready to install for his guy.  Plumber arrived right within his two-hour time window and knocked it out quickly and professionally.  Saved a couple hundred dollars over another estimate I received.  Update Note:  My new, Moen faucet had a manufacturing defect - another small leak!  Even though it wasn't really their issue, I reached back out to Lyons Plumbing.  He had one of his guys stop by a couple days later for a re-install... no charge.  It's not how you make money as a plumbing company, but it is definitely how you get satisfied customers and repeat business!

Awesome.  Great job, fast service and good pricing. Steve is the man!!!  Highly recommend.

I retained Steve Lyons a year ago to fix my water heater.  He got good reviews online, and he seemed nice on the phone.  Unfortunately, he misdiagnosed the problem and I spent over $600 (which was double his estimate) for nothing.  His pleasant demeanor quickly faded when I questioned the bill and the quality of the repair.  
He also advised me to go online and research possible pipe configurations and different check valves that could solve the problem my water heater was having.  Isn't that the plumber's job?!?!
Just a bad experience and I will never go through him again.

I received a bill of over 600.00 and every item that was fixed broke within a year. I even got 700 dollar water bills for running toilets. I had to get another person to redo all of his work. I blew too much money on this man

Steve is a great guy - personable, funny, professional. He follows up in a timely manner, and stands behind his work. I've been through a lot of plumbers, and Steve is definitely the best!

Stephen has been our plumber for many years. He is personable and dependable and gets right to the problem. We would not call anyone else as he is extremely trustworthy!

Family-owned, friendly, responsive, knowledgeable and fair-priced.  These guys have been my go-to plumber since we bought a house many years ago.  They have been around this area for a long time, so they know the ins-and-outs of the plumbing in the various houses.  They are also respected by WSSC, and this came in handy when tree roots were clogging our sewer line beyone the limits of our property.  WSSC did not even question me when I gave them Steve Lyons name, reimbursed us for the expense, and (eventually) replaced the line for us.  I can't say enough good things about 'em.

They come on time, find the problem (or lack thereof), don't do any work that isn't necessary, can work on ancient houses like mine, and their prices are fair. They make every effort to save you money (fixing rather than replacing or giving you do it yourself tips for something really easy). Go no further. You can TRUST them.

I agree-excellent and competent service.  We called with a leak, and they were out the next morning and quickly diagnosed the problem (turned out it was an HVAC problem-not the plumbing).  We'll definitely use them again.
