Best Backflow Services in Washington DC

Quick and accommodating. Recognized issues and new how to resolve them. Great value.

First-rate job of responding to, diagnosing, and remedying a plumbing emergency.  Very knowledgeable and great to work with. Highly recommended.

Heil Plumbing has been out to our house in Howard County several times and the work is always really well done and the technicians are professional and communicative. We've had them install a new water pump for the well, fix leaks, and iron out issues with our water heating system.

Each time, they have been great to work with. Their prices are fair, and their service is really top notch. Some members of the industry are clearly happy to fix an issue, collect a check, and be on their way. It's evident Heil Plumbing cares to help make homeowners more knowledgeable and better equipped to make informed decisions. I appreciate that a bunch, and they'll be my go to plumbers for years.

Donzelle was awesome.  We had an emergency plumbing situation (backup flowing up through my tenant's shower drain...pretty gross), and Donzelle was the first person to respond to my requests.  His communication was excellent throughout, his prices were fair, and he responded immediately.  He was also able to work with the tenant to find a time that worked best for everybody for follow-up work.  He didn't try to upsell or pressure us based on the situation and his quality of work was fantastic.  Sent pictures and updates throughout, cleaned up, and my tenant also reported that he was very satisfied.  Super professional, 5 stars.

Mathugh was a very knowledgeable plumber and I am glad he was able to make it out on the same day which I requested. Out of the five quotes I received, he responded quickly and provided a great price. My dishwasher issue was promptly resolved and fixed to the standard and codes as it should have been previously. My condo does not so good workmanship. I'll definitely be using Mathugh again!

Jorge at Drain Works is very knowledgeable and responsive. He helped us fix our fireplace and clean the glass, and helped answer our questions about installing a mantle and more. He was able to come out within a few days of our first communication. Plus, he's such a pleasant guy! We will plan to go to Jorge as our first choice for our future needs.

came out same day, were super responsive despite me being difficult to contact! Work was great and cost exactly what was quoted. 10/10 would recommend.

After: picture was of bathroom being remodeled. Friendly workers, he responded to messages and contacts quickly. Would definitely recommend to family and friends.

Needed my garbage disposal replaced. They showed up on time, were efficient, thorough and professional. Would hire them again for any future plumbing needs.

Kudos to DMV plumbing for assisting me with a problem with my kitchen faucet. Elliott responded quickly and advised me of a quick fix.  He said if I couldn't fix it myself, he would come over to do it. And his quote was quite reasonable. Although I ultimately did not use his services, I appreciated his advice which helped me fix the problem myself.  I will definitely contact this company again for any future plumbing needs I may have.

Mahon plumbing saved us a ton of money on a main water line replacement and did an excellent job.  They gave us a quote and were out to start the job a couple days later.  They did a quick, great job and I couldn't be happier.  We had a couple other quotes that were much higher, mahon is great.

The office employees are not familiar with HVAC terms so they assure me they were familiar with ERVs and works on them all the time...when the tech came out he told me he never worked on one but he assured me they'd fix it...
After 2 days I called again to get the estimate and I was told that they were working on it...
After 4 days I called again and they told me they were working on it...
After a week I called and I was told the tech was in vacation so I had to wait... WAIT WHAT?!?
I was waiting and waiting and then after 2 weeks I was told they were not interested in the job...
Another HVAC company that prefers changing filters/belts and doesn't know how to actually fix problems.

UPDATE: Patricia from Clover replied to my review stating that I may be confusing them with another company. The technician I dealt with was Joshua Pickett. By blaming the customer you're just going to make it worse.

Called Northeast Plumbing once to repair a leak and haven't had any issues since. Plumber was punctual and very knowledgeable. Will call for future plumbing needs!

I had my sump pump replaced by these guys. Dustin came and did an excellent job. He explained what he was doing very well and took the effort to clean up the area afterwards. No hassle. I would recommend him to my friends who has plumbing needs.

Mr Loumni rates way more than just 5 stars, and not only for his superior plumbing ability and for his honest assessment...

It is Thanksgiving time of year and Mr L is booked to the max, yet knowing the difficulty of not being able to use a kitchen sink he still came to our house to fix two unrelated problems in two weeks. The first time was to replace an old leaking (into the cabinet below it) kitchen faucet.  The 2nd visit was to repair a stopped-up kitchen drain that occurred Thanksgiving day, also for a  badly rattling garbage disposal. We called him to unclog the drain and replace the disposal but he discovered the problem to be simpler than we thought.  He saved us a lot of money. He's our hero for being a great plumber and a good hearted honest gentleman.

He was great! Knowledgeable, and a fair price. Will use again. A nice local guys. He viewed our sewer line for roots before new driveway was put in. Also, cleared the line and gave good suggestions.

They sent the same tech out again (Juwan) on Oct 26, 2020 to check our systems. He told us that the fan motor was going bad and would need to be replaced. We told him that our system (a Lenox) was still under warranty and the part should be covered. He said he would have the office look into it and that we should only be responsible for labor. Annoying, but that's the way the game goes. He also said he was unable to complete the check in for the HVAC system since the numbers wouldn't read right with the motor not kicking on consistently.

We are waiting for the call that never came. I ended up calling on Oct 30 to figure out what is going on. At this point I talk to someone in the office (Zach) who tells me that he tried to call me on Tuesday and left a message (which I never received). He told me the expense would be $700 - this was an hourly rate and it was expected that the job was going to take between 2 and 2.5 hours to complete. He told me the hourly rate was $305/hr (which I wrote down and confirmed for later reference) and he assured me that I was not being charged extra labor time due to the complications of the system being installed backwards by them. He also told me I should be receiving a 10% discount off the labor because of my maintenance agreement so my charge is likely between $630-$700. We scheduled the install for the following Monday, Nov 2.

Moving forward to the install, they sent out the tech (Juwan again). Tech arrives at 2:30 pm and finishes the job at 3:25pm. He then proceeds to go out to do the maintenance check. Once finished, he quotes me $610 for the job. I tell him to call because that number is too high because he only completed an hour of work and this rate was for 2 hours. He called and kept telling the office that he had completed 1.5 hours of work. After the 3 instance of this, I countered that he had only worked for 1 hour. He looked at his watch and said, Well, I got here at 2:30..., to which I responded, Well, it is now 3:36 pm, which is 1 hour and 6 minutes of work. He then told me he would only charge me for an hour of work - another lie.

He talked on the phone with someone and told me I would be charged $325, which was the cost for 1 hours' worth of work. I asked him if I would be receiving the 10% discount on the hourly rate as I had a maintenance agreement. Tech responded that I had already received a discount and could not receive multiple discounts for the same service. When I asked what that discount was, he told me I was receiving a discount because my part was under warranty. I told him that was not a discount - Sila was going to be paid by Lenox and were sent the part - it did not cost them money and I was paying for the labor so no discount had been applied.

At this point, tech (Javon) says, Well I just have to charge what they tell me. Can you just pay it and take it up with them? There is nothing I can do at this point. I am pissed but figure I can talk to someone at the office to get this taken care of. BIG MISTAKE.

I called once the tech left on Nov 2 at 3:40 pm and am told the manager and billing has left for the day. They take my message and tell me that they will call me back tomorrow. Of course, no callback. I call the next day, Nov 3, at 3:59 pm. Again, there are no managers and I am told I will get a callback the next day. I called back the next day at Nov 4 at 1:22 pm hoping to get someone get this.

I am on the phone with Zach again. We went back and forth before he said, So you're looking for the 10% off this price, right? Then I will go ahead and put that on your record, send you a new bill to reflect that, and you should receive the credit in 3-5 business days. Will that make you happy? I was frustrated and said, Yes, fine, that will work for me.
Surprise, surprise, no bill and no credit on my credit card. I'm done with this company - I want my money back from my maintenance agreement, my HVAC to be reinstalled correctly and to never work with them again.

I called up T-E-C on Friday late afternoon before Memorial day Weekend with a broken A/C unit and a forecast of 90F through the weekend.  
I had taken apart the evaporator unit on my A/C and all signs pointed to my system being low on refrigerant.
I got a call back within about 2 hours and was offered an emergency visit over the weekend --which I should have taken, but thought it wouldn't be too bad-- or a visit on the next Tuesday (the next business day).

They dispatched JJ to my house and called me about 30 minutes before he showed up.  

He quickly confirmed that the unit was low on refrigerant and it took him about 15 minutes to get everything charged and back to normal.  

There was one  small mixup with the dispatcher - I told them that the condenser was on the roof and that access required an 8/10ft ladder. He informed me that it wouldn't be a problem.  When JJ showed up he only had a 6ft ladder and a 30 ft ladder. It looked like it was going to require a second visit but JJ made do with the 6ft ladder - and some good climbing skills.

From my experience - I'm happy to recommend these guys.

Kevin was on time, courteous, informative, and very friendly. This was the second time he has been to our house and I would highly recommend him to anyone who asked.
