TONY was the best! Really quick, respectful, easy. The overall experience was so seamless. Their texting reminders and their alerts on how far they are from your location is so great. I definitely recommend Cornwall Plumbing and Heating.

We had a difficult situation doing to another come
Doing an unprofessional job. We needed an LG certified company to work on our system.
Cornwall drove from Ct to the Hill country in the Berkshires of Massachusetts . Joey was very professional competent and kind. He diagnosed the problem and worked with my electrician to help solve the problem. I would recommend Cornwall plumbing
For any AC needs you will be lucky to get them.
Wish I called them first.

We used them urgently in the past for repair of a toilet and unclogging of a kitchen sink and although the work was fine, it seemed overpriced. However just recently we had them look at a problem we were having with a partially clogged pipe in the basement. The told us it would require use of a commercial snake/auger which they had, but unfortunately had recently broken during the course of its regular use. They said, that to do the job, they would have to go rent a snake for the job and pass the entirely of the 275$ cost onto us. This despite the fact that they admitted they were going to repair

I want to give these guys a shoutout for an amazing responsive. On Thanksgiving night at 10PM I had a massive leak in the basement. I called their emergency response line, and within 15 minutes got a call back. I talked through the problem with the plumber and he offered to come out then in the middle of the night, but the leak had stopped. He came out the next morning at 9AM and dug up the septic tank to find the source of the clog, saving the basement and Thanksgiving weekend. I'm very appreciative of their fast response and hard work fixing the plumbing

Professional and prompt in solving a big job for us in replacing and upgrading our well tank and water filter equipment. Flexible, smart, experienced, courteous, and went the extra mile in customer relations. Plaudits for Randy and his assistant Mike. Nice to know there is a great neigborhood plumbing outfit we can call on when we upgrade bathrooms this coming year.

Cornwall Plumbing was called on a Sunday afternoon after a DIY project went, well, let's say not as planned. I left a message and within 30 minutes Joey called back and was at my house within 45. Joey (who I found out was the owner) was very nice, communicative, explained some options and worked clean (a good quality in a plumber). The job took about an hour and was charged a very reasonable price especially for a Sunday call. I highly recommend Cornwall Plumbing and now that my DIY impulse is behind me I will be using them for all my plumbing and heating needs!

Cornwall installed a whole house water filter system and did a great job. They arrived on time, were very thoughtful of where to place the unit for servicing and very professional in completing the installation. They priced the job very competitively compared to other quotes. Highly recommended.

We had plumbing problems at our Sharon house for many years, despite countless efforts to get the plumbing fixed and the installation of a completely new septic system. We decided to finally get these issues truly resolved and contacted Cornwall Plumbing & Heating. They sent a team out and did a thorough and careful diagnosis of the problem. We were immediately reassured that this time we would get the plumbing system truly fixed--and we did. The team from Cornwall Plumbing & Heating showed up on schedule. As they progressed on the job, they showed us what needed to be done and why. We are deeply

Last winter, faced with soaring electric bills, I purchased a NEST thermostat to better regulate my heating and had Cornwall Plumbing and Heating do the installation. Their representative took a look at my old wiring and gave me an honest estimate of the cost upfront, which was most appreciated. They did the work promptly and well. I definitely plan to use them again for my electric and plumbing needs.
