Loved the service! Great guys! On time! Nit and clean job! Could not find a better company and people for any plumbing work!

Great communicators and honest people. They were able to come by quickly for estimates and advice on the plumbing, heating, and HVAC in our new home. They were the only company who clearly differentiated between what really needed fixing and what we should just keep an eye on for the future. We'll definitely use them again.

I saw the beautiful work 781 does here on Yelp and decided to give them a call. Stan showed up the same day to service three water heaters. He noted that two were quite old, and offered to replace them for a fair price. They serviced the one for free, replaced the two within a couple hours, and followed up to make sure they were working well. They take pride in their excellent work, and I always felt like I was getting a fair deal. Highly recommend.

Reached out to 781 late Sun night and they came by first thing Monday morning to look at the situation.

The conventional fix wasn't going to be an option thanks to our old house which they communicated clearly and were able to assist with a quick repair to solve the issue.

They were insistent on doing an additional upgrade to deliver the value of their $250 retainer and we appreciated that mindset. Would use them again in the future.

We had a boiler that wouldn't stay lit - we placed a request into 781 on Saturday night and by 10 AM the following morning, the team was out to repair the boiler within 20 minutes and explained what had gone wrong. They respected social distancing guidelines and were very friendly. I would absolutely recommend!

After talking to a few plumbing and HVAC companies regarding inconsistent hot water, I decided to go with 781 because they were able to explain clearly what they thought the issue was, and how they could fix it for a reasonable price.

While they were in the house to do the boiler repair, I asked about a couple smaller projects I would like to address in the future. Not only were they up to the task, they offered to complete the other projects as soon as the work on the boiler was completed the same day.

Compared to other companies I talked to, 781 spent their time explaining what COULD be done, instead of how it would be difficult/expensive to complete the work because of less than ideal conditions in an older house. I'm no plumbing expert, but the completed work looks great and everything worked as expected when the water was turned back on.

781 did an amazing job in my condo unit. Complex toilet set-up with rear-facing exhaust, they were fast, professional, and low cost compared to some of the other plumbers around Boston.

We had a really difficult time finding someone to install a new dishwasher. These guys were the only reliable ones who got to us quickly and took care of everything efficiently. They even took out the old one when they left, which I hadn't even asked for until they arrived, assuming they wouldn't be able to do it. Really solid work as well, all around. They even fixed our kitchen sink's water pressure even though we didn't really ask for it. Recommended.

781 was able to take care of my water heater replacement same day and worked late in the day to resolve my problem. They were very responsive and easy to work with. Pricing was competitive to other businesses. Will look to do more business with them in the future.

Great experience working with them! We had a pump break on our boiler. I called at the end of the day (right at closing), and he came by to asses it for free. Very fair price, gave honest feedback about our options, quick work, and thoroughly explained what he fixed after the work was done. I'll certainly be working with them again to fully replace our very old boiler.
