"Matthew was very quick to get back to me and get the job done right. I had a leaking toilet that was not seated correctly so it ruined the floor beneath. I had this issue fixed 3 times before. Matthew came out and replaced the flooring underneath it and now it sits correctly on the floor and no longer leaks. I would definitely have them come back if I had any other plumbing problems"

"Joe and his team were precise with their estimate of the problem. They arrived on time and were ready to go. Had all the materials needed to do the job and knocked it out within a matter of hours. When I asked about an additional service for the refrigerator water line, they jumped right on it. To have my well pipe raised, a new whole house filter system installed and the refrigerator completed, was under $1,400.00 and the systems have worked like a champ ever since."

"The servicemen were exceptionally polite, knowledgeable and professional. They diagnosed a long standing problem that other plumbers did not and fixed it right then and there. I thought the price for putting in the new vent on the pump was great ($475). $200 for cleaning out the shower drain (full of hair visible to the eye after they popped the cover to show me) was a little high. But I would definitely hire again if needed. Thank you!"

"I didn't actually need DrainWorks to do work in my house. I had some standing water in my basement drain and I wanted a pro to look at it and make sure it was ok. Justin from DW assured me it was normal, likely a result of elevevated ground water due to recent storms. I also asked him about installing a back up sump pump and he made a different recommendation that made a lot more sense. He was knowledgable and friendly and gave great advice - well worth the $69 consult fee for his expertise and the peace of mind it provided me."

"I could not be more pleased with this company or this service. I found them here on AL and with a rebate, it was a great deal. When I called, the woman who answered was extremely polite and helpful and took the time to go over the entire audit process with me (she wasn't rushed as some receptionists are). They sent an email to confirm the date and time.
When the team arrived, they were on time and each of them introduced themselves by name to me before coming into my house. They were all very polite and courteous. The leader (I can't remember his name) gave me an overview of the process and explained things as they went. Basically, they simulate high winds around the house and then monitor for where leaks are. My house is relatively new and has no basement, so it was already pretty efficient, but there were some major leaks by the front door and attic door, which they sealed on the spot. They also showed me that I could hold my hand over any electrical socket, even ones on interior walls, and feel the "wind"--which means air was leaking out those! So I plugged them all with those little socket protectors. The guys also took me into the attic and showed me some leaks, and fixed them--and fixed the attic door by adding a little latch to help it stay closed. All in all, they reduced the amount of air getting into my house by 500 (I forget the units). It was clear they didn't just make up this number--they showed me the number after the first test and then after the second test (when they had treated the problem areas).
I also got a few free CFLs and LEDs, and bought 3 more LEDs since they were at a great price. They left some rebates with me, although all my appliances are new so I didn't need anything. 
When they left, they each said goodbye and were very professional until the end. They were respectful in my home and asked before opening any closets or doors, etc. I felt very safe with them here, which is not always the case when people are in your home working. I think the price is a fantastic one, especially with the AL rebate that was on when I scheduled. I feel I got my money's worth. My husband and I had tried to plug some leaks ourselves, but we didn't really know what we were doing and we had no way to measure if we were really helping anything. This audit gave me hard numbers to look at and I was impressed that they did the fixes on-site (included in the price--for instance, they plugged a whole around my front door frame by installing a clear plastic barrier). It was a great deal and a great experience. Highly recommend!
Bonus--when we resell this house in a few years, I will definitely list that we got a professional energy audit performed on it and that it's very efficient. Definitely a selling point!

FAQs for water heater repair or service projects in Hanover, 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.
