"I found TriState Home Services on Angies list and contacted them. Since it wasn't an emergency I scheduled them to come out the following day. The Plumber (Chris) did a great job assessing the problem with the leaky faucet and indicated that given the age of the faucet (41 years), he could attempt to repair it but wouldn't guaranty how it would last and recommended that I replace it. I agreed with his advice especially considering the price comparison of repair vs. replace - the price was reasonable. The quality of the work top notch, on time, and as promised. I would recommend TriState Home Services and will use them in the future."

"This was a last second thing. Our hot water heater died on us. Left him a message on Tuesday afternoon. He showed up first thing next morning. Right on time. Discussed the job and he gave me a estimate with a small window. And he said he could have me back with hot water in a few hours. Sure enough less then 3 hours later I’m back running. Very good and clean job. Very professional with all aspects of the job which was nice. Best part of it all when it’s time to pay his his price was barely over the low end of his estimate. Everyone else would most likely been barely under the top end of their estimate. So a very good clean job done as a rush for a good price."

"This company is nothing other than excellent. A bit pricey, but you only get what you play for - and I got plenty. On Saturday afternoon, I found out that I needed a complete sewer line replacement. By late Sunday afternoon, I had one! The crew had to dig down about 10 feet to remove the broken line and then had to tunnel under my patio to get to the cast iron pipe in order to connect the new line. After the installation, the dirt was replaced, the area was seeded and covered with straw, and the sidewalks and parking lot were sprayed clean. Every single guy in the crew was friendly and knowledgeable. Special thanks to Gregg, Chris and Mike. I have recommended Mahon to friends and family and have already scheduled another job. If you need a good plumber, whether for something major or minor, I highly recommend Mahon Plumbing."

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

FAQs for water heater repair or service projects in Frederick, MD

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.
