"Had a client in a multi family situation who needed a tremendous amount of existing cast iron replaced in one day. Matthew was hired to remove and replace with new pvc. Got it done in a timely manner so residents would not be down all day and could turn the water back on quickly.Would highly recommended to anyone with all plumbing repairs."

"I called and asked for an estimate to convert my DHW from the oil boiler tankless coil to a 50 gallon A.O. Smith Hybrid water heater. The owner gave me an estimate same day and was able to do the installation later in the week after calling him last minute. Him and his crew were on time, very quick, extremely OCD on pipe placement and appearance of their work, and tested everything before they left. I made things difficult on them with the short timeframe and having the electrician here at the same time but they didn t complain and worked great with the electricians to get the project done for us. I had 8 different companies give me estimates and hands down they were best pricing, most honest, and friendliest company I worked with!"

"Not the best, but I guess not the worst either.
They did the door blower test which revealed different air leaks in the house. They sealed around some of the doors in the home, installed some door sweeps, caulked around baseboard registers etc. However, the work was far from consistent and less than professional in quality.
There are 15 registers / returns in the home and we were told they would caulk around them all, they caulked around 7. 2 of which the caulking was so thin that it cracked before the next morning.
There are 3 sinks in the house where pipes were supposedly "foamed and insulated" on their report. There is no additional insulation visible anywhere that I can see.
We are entitle up to 40 CFL light bulbs in the home, however, even the 30 they said they changed were not completed.
For example:
-there are 2 nightstand lamps in the bedroom. One lamp received a CFL and the other wasn't touched.
-there is a hallway ceiling light that was supposed to be changed out with CFLs, but still has the same old bulbs.
-downstairs bathroom still has all three original bulbs
-two bedroom ceiling fans that take regular "A" type bulbs all have the same bulbs
I sent an email to the gentlemen who came out to the house asking if we could at least receive the extra bulbs. He did respond and said yes, but never got back in touch with me. After the general overall experience I did not bother chasing after them for a few more dollars worth of bulbs. However, the whole point is not the money, its the fact that these were all listed on the report and not completed accordingly.
They did recommend an insulation company to come in and give us a quote and also told us about different programs offered from the state which would allow us access to rebates for making home energy improvements. All in all, I guess it helped us to know where the air leaks were in the house, but the overall performance of the team was simply sub-par. They were nice, polite and somewhat informative but by no means "wowed" me.

FAQs for water heater repair or service projects in West-Mystic, CT

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
