- Closely follow the average True Cost Rate furnished on the Homeowners section of Home Advisor for labor costs - Show up on time and give up front estimates - Focus on service work and limited multi-day projects so my schedule remains fluid - Advocate on the customer's behalf shopping for best prices on quality materials and best practices to get jobs done to code at the best rate possible

"We had an issue with a Dry Well periodically backing up. Damian and the D Day Plumbing team were very professional and knowledgeable and provided an estimate with a couple different options and their related costs. They installed a new utility sink, sink pump, and needed piping and valves with tie ins to the main septic. They made improvement above and beyond the initial job breakdown, all the while staying within budget. I will certainly consider them again for any future work. Thank you Damian and the D Day Plumbing Team for a job very done!"

"Hired pro comfort to upgrade to a ductless heat pump system. The experience from start to finish was seamless. They handled all the loan and rebate paperwork for me. They also provide the rebate upfront so it was applied to the job which felt was really helpful. That aside, they stood out with their level of expertise. It was a big upgrade for us and we wanted to be sure we picked the right design and it done correctly and I?m confident we did. They were so thorough and even when I had questions about how to use certain functions on the unit they returned to my home to re-explain them to me. Very pleased with everything and I know I can trust them should something come up. I opted for Mitsubishi because of the reliability as we removed our oil system completely so it was a tad more than others offering other brands, but a far superior product and less future issues felt worth it to me.

"Bought a heat pump from them 3 years ago. Cooling has never worked in the summer, heating fails twice every year in winter. Even when it works it can't heat the house over 65 degrees. The problem is always the same, a leak in the line they installed. Instead of fixing the leak, they refill the refrigerant every time and charge me a few hundred dollars. Every time I have helpfully told them about the continuing leak issue, but they don't listen. Now that the heat pump is out of warranty they are recommending a $3000 repair of the problem they should have fixed three years ago."

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