Customers say: Quality work

"Mr. Floros worked with my schedule on a short timeline to replace our water heater. He professionally negotiated with me about how to get the job done approximately the way that I wanted while still meeting local code. When the job was completed, he cleaned up and took away the old unit. The price was a great value considering the work done."

"Matt called me back promptly with all information I needed to make a decision on new hot water heater. Matt and his colleague Sean arrived early, did work as discussed and cleaned up all areas and left area cleaner than when they arrived. I feel that job done well and I appreciated the honesty in his recommendations and what I needed. Would hire again and recommend to others"

"Marcin and team did a great job redoing the plumbing in my entire house. We also discovered cracks in our waste line and he replaced all of the original cast iron lines in the basement and coordinated with the contractor who replaced our exterior water and sewer lines unexpectedly. He was quick to respond to questions and requests, very reliable, and did a great job plumbing 2.5 bathrooms, laundry, and kitchen."

"The company was professional and responsive from the consultation to the office staff to the various people who worked on our project. I had tried to contact about 10 companies to get our heater/ on demand hot water heater replaced. Addario's was the only one who responded immediately and was able to fit us into their schedule to get the work done. We had contact with at least 8 staff people in various capacities, and all were professional, polite and knowledgeable. We also appreciated the senior discount for our project and assistance with the MassSave rebate process.. It has been difficult for us to find service people since we move to Gloucester. We were surprised that the company services this area and we would definitely use them again for plumbing or electrical services."

FAQs for water heater repair or service projects in Charlestown, MA

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.
