Best Water Heater Installation in Boston MA

Just had Kevin wtih Big Blue come by this afternoon to go over a few items in my condo (entire furnace blown, hot water tank, etc). He was courteous, timely, professional, confirmed a few things that were already quoted via home inspection. Made recommendations, let me know what would work and what wouldn't.

I would highly recommend his services and feel comfortable with any future needs!

We are VERY HAPPY with Greg's service!!   He did an excellent job in installing a new water heater for us.  Greg's is very professional, responsive, knows what he's doing, listens to our concerns, takes the time to explain and answer our questions, his estimate is right on, his price is very reasonable.....   Out of the three plumbing companies we had contacted, his quality of work, customer service and pricing are the best.  After the job, he took the time to walk us through everything he did and cleaned up everything.   Plus, he's a dog lover too!!   My husband and I are just happy that Grey's here...... Yeah, we finally get hot water!!!!!!!!!!!!

Responded quickly, very professional and fixed a leak for a reasonable price. Would use again and definitely recommend!

Absolutely, hands down the best plumber and one of the best contractors I have ever worked with. Jodie, office manager, is on top of everything.  Every phone call is returned promptly.  I manage a large museum-lots of plumbing-and Consolidated Plumbing has been a pleasure to work with.  And I've been working with them for years.  Never a disappointment.  Can't say enough nice things about this company.

Could not be happier with the level of professionalism and price point. On top of that, Mike was able to come the day we called. Stumbled upon them via yelp desperately looking for help and as new home owners have definitely found who we will be using for all future issues.

Call this company because I needed a water heater replaced they came on time and did a
Great job a highly recommend this company great service

had them put in a new boiler and oil tank they did such a great job. I could not believe how quiet and efficient they were  they left the place cleaner than when they came. All workmanship was top notch and very professional .If you need service or a new boiler these are the people to call. Thanks to all the crew and the girl who called from their office you are the best

I had to find a new HVAC person to get a furnace inspection and to check my TP valve on my water heater since my last guy was no longer in business. I went with Welch Brothers based on just reviews on Yelp and I'm glad I did. I made an on line request for service and even though I didn't receive a confirmation call or email, they adjusted their schedule to accommodate me.

Jim was awesome. Very friendly and knowledgeable. He explained everything to me simplistically. When he measured the pressure from the water heater, he made recommendations on how to handle the increased water pressure along with a quote for the parts and labor. He installed a new TP valve in the meantime to see if that will fix the water drainage but didn't push the recommendation unless the new TP valve didn't fix it.

I would definitely go back to them for future service!

Andrew quickly responded to my request online. Scheduling a site visit was easy. Once on-site, he swiftly diagnosed the problem was an outdated toilet, and gave great recs on buying a new one. With a new toilet purchased, he installed it in under an hour. Thanks for making this process straightforward and painless.

My neighbor recommended me Frank, because of very good work with reasonable price. Along these years I asked Frank to replace my water heater, garbage disposal, along with several everyday plumbing stuff. He has been responsive and a life saver. I just sold my house and I will definitely recommend Frank to the new owner.

Welter is the Man!  

I have an aging Buderus GB142 condensing boiler that has been having those old age boiler things happening. I had been using a local service with a monthly support agreement but recent experiences with under trained techs led me to search for someone more familiar with my boiler.
After having been quoted $4,900 to repair my boiler for error codes and inaccurate pressure readings from Company A, I contacted Welter and he came in and assessed a few problems. The issues were addressed efficiently, parts were replaced, connections were repaired the boiler was deemed ready for service and the total bill amounted to less than 20% of Company A.
Long story short, Welter is an experienced plumber, heating pro, with a positive attitude and excellent troubleshooting skills. Highly Recommend Welter for any heating / hot water issues.

I had Casper out to install a tankless water heater. I could barely get them to give me an itemized quote before they arrived. After installation, it took 2 weeks and badgering phone calls/texts to get them to send me a proper invoice I could submit to Mass Saves for my rebate. They did a good job, installed as promised, and did as I asked. However I won't work with them again because of how big of a headache it is just to get a proper quote, nevermind an invoice.

we had an oil burner service company for 20 years and the owner retired a few years ago.  we thought we would never find that level of service again. we decided to convert to natural gas, and we used mainstream mechanical. we also installed a whole house generator.  these guys do great work, are professional, and know their stuff!  we are always assured that no matter what time of the year, day or night, if we have a problem they are there!  we highly recommend mainstream.  Lisa and Richard M.

Based on the other fine reviews I gave Matt a call.  Henry and John came to my three family house and did a major repair to the main cast iron drain between my second and third floors. I knew in advance there would be some demo work required so they could inspect the pipes, but Matt said not to worry and that they would do the demo for me.  What a relief.  After the demo, they inspected the pipes and explained to me what work needed to be done.  I felt confident they were giving me good advice and not selling me a bunch of working I didn't need so I readily agreed to their proposal.  The job was quite challenging cutting cast iron with a reciprocating saw it tight quarters, but the guys were real professionals and were not deterred.  They put forth great effort in getting the old cast iron removed.  After installing the new pipes they were very meticulous in ensuring there were no leaks and cleaned up all of the mess.  In my estimation, I received high quality work at a fair price.  I will surely have these guys back when I need future plumbing work.

Never was a company more accurately named! If I could give Simon from High Quality Plumbing a ten-star rating, I would. From the start when he sent me a calendar meeting invite for the initial consultation, I knew I was dealing with a professional. Simon and his assistant, Nic, replaced a poorly installed Navien combi boiler that controls our heat and hot water when it suddenly died in the middle of winter. We'd had recurring problems with it because of the poor installation. It was a lot of work to replace, and he and Nic worked diligently to get the job done so we could have our heat and hot water back on as soon as possible.

Simon installed a newer model Navien combi boiler that is much quieter and has several new features. He also added several redundant valve shut offs to make future servicing of the system as easy as possible to keep it running efficiently. He explained what he was doing every step of the way, and why each of the components were necessary and what they did, sending links from the manufacturers so I could feel comfortable with his suggestions. He was thorough and careful in planning the system as a whole. When a stubborn problem arose with one of the components, he followed every lead to make sure it was adjusted properly.

After the job was finished, Simon was diligent in making sure that the system was tested properly and that all the valves were labeled so that we knew where the gas and water shut offs were in case we needed to shut off the system in an emergency. He had a city inspector come in to approve the work, so you know he had installed everything according to code. It was approved on the spot with no problems.

I can't say that I've ever had this good of an experience hiring a contractor to work in my home before. He and Nic were respectful,  professional, and considerate. They put drop cloths down where they worked and cleaned up the space afterward. Every evening, they would make arrangements for what time they would each be arriving the next morning, and they were always on time and stayed into the evening some days. I wish I could hire them for every job needed around our house!

After posting my previous review about how dissatisfied I was with MacCo, the company CEO (Stephen) personally reached out to me about a month after my initial review was posted.
After speaking with him for about 20 minutes on the phone and explaining exactly what had happened, he agreed with most of what I had to say and assured me that this is not how they run their business.

It has now been 2 months since my conversation with him and during the entire time, he assigned one of his supervisors to my case and was personally involved (through email) in making sure everything was running smooth. As of last week, the issue with the A/C unit at my parents place was finally resolved and corrected. On top of that, the water heater system was also serviced as a complimentary service for the inconvenience.

I decided to update my review not because I had to but rather because I got the feeling that Stephen genuinely cared and wanted to do what was right. Unfortunately, when companies grow and become very successful, they tend to forget how they got there and they don't always reach out to the dissatisfied customers but thankfully Stephen did.

Lastly, I'd like to let everyone who is reading this and other reviews to know that just because you found one bad apple, it doesn't mean you should give up on the whole tree.  
I am satisfied with their work and will continue to use their services in the future knowing that they have a responsible person guiding their team.

Had the pleasure of having Ron come out and replace the shut offs on my washing machine. He was on time, courteous, used Covid precautions and was very professional . He was able to come by the very day I called them and was very reasonable with his pricing.
 I would definitely recommend them and look forward to working with them again in the future.

Mike Richard has done outstanding work at our home over the past 8 years. He works so efficiently he actually jogs to his truck and back to get any needed supplies. Mike is always timely and communicates about any issues that he finds, offering various solutions. Most recently, he put me in touch with other contractors that have also done superb work.

STAY CLEAR FROM THIS COMPANY! Wish I could give a negative star. Very very dishonest! Came and tried to prolong work hour by unnecessary job. The main guy is a big talker, and wastes your time by his life story and investment strategies, and you have to pay for the time he talks! A 30 minutes work eventually took them more than 3 hours to finish. They lied about a machine's price and charged very high price for bringing it to the house. Will never ever use them again. Take my advice, stay away from them!
