"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"

"In the time of COVID-19, my husband and I had a hard time finding a plumber to come out as swiftly as possible when we noticed discoloration on the wall behind our toilet. Tim came recommended through another, very similar reviewing and contracting website, and we could not be happier. Within an hour of speaking with him, he was at our house assessing the job. He removed the toilet, cut into our wall (very carefully and as neatly as possible), replaced our original copper piping with pex tubing, and reinstalled the toilet - all on the same day. I could not be happier with how quickly and efficiently he got us back up and running, as this is our only bathroom. We received our invoice promptly with a detailed explanation of the work performed and also a picture of the repair. Very fair pricing for the extensive emergency repair required. I plan on using Tim again for all future plumbing work. We highly recommend him!"

"Needed failed hot water heater replaced. Campbell installed a new replacement the next day after being called. Two installers plus the business owner showed up on time and quickly made the swap. Will definitely use again for plumbing need."

"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!"

"The service was great. They gave a lot of really helpful suggestions. They replaced our bulbs with low energy bulbs. They put in weather stripping in areas needed as well. They were great to work with. They gave a detailed report on how to lower our energy usage."

"I have an annual contract and the automatic filling works great. My only complaint is the skyrocketing cost of the annual contract. It also includes annual checkup of the heating system.
You need to negotiate the cost down to what others charge, i.e. half the asking price.

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