"If you need plumbing done or a new water heater, look no further- Brian (the owner) and his crew are top-notch, honest, and professional. As first time homeowners, my wife and I had a lot of questions and Brian walked us through everything. He is extremely responsive and fair in his pricing, and the team he sent out to replace our water heater and a couple of valves (Joseph and Sam) were friendly, efficient, and professional. I will 100% be contacting Brian again for any future plumbing needs. A+ service and communication!!"

"Vince told me outdoor spigot could be repaired and did not need to be replaced which saved me money. He also replaced a vanity faucet which I provided. He was quick, efficient and honest. The most important thing was he discovered a serious problem with the way my water heater was vented. The exhaust pipe had been cut wrong and glued together. It was ready to come apart and could have vented carbon monoxide into the basement. (We do have CO detectors but this is still scary) We had this water heater installed a couple of years ago by another well known local firm that I don't know if I can name here. It did fail inspection by Howard County 3 times after initial install. Failure was all related to the vent and probably should have never passed. Anyway, by pure luck it was discovered and fixed. Thank you Vince!!"

"My Remedy Plumber arrived on time and didn’t really charge me for his service because he stated what he needed to do may not fix my problem because I needed a new faucet which he did not have. Water was running from both the tub’s faucet and the shower head. After pulling off the faucet and making a minor adjustment to a washer within the faucet the problem was "temporary" fixed, the washer was damaged. He stated that a new faucet was needed and that I could call back to have that installed. I thanked him, gave him a small thank you gift, and he was on his way. I was thankful that this plumber had "integrity" and did not try to overcharge me for work that did not fix my problem. I would surly hire this company again!!"

"They were up front with what is wrong. Provided explanation of the quote. Asked permission to get access to places. They explain the reasoning for the cost and the risks if ignored. Pricing was fair. Went above an beyond to solve the water heater issue we had. Even calling in an electrician to help with a fix. They were on-time to early on their scheduled appointments. Excellent customer service."

"We had an emergency.  As DIY'ers we inadvertantly, while installing a new bathroom vanity and re-connecting the water lines, put a drywall screw through the copper supply line.  We called 3 Plumbing companies on Angie's List.  Mahon was the only company who immediately called us back to say they could have someone there in 15 minutes.  Twenty five minuts after we hung up, the Plumber had arrived and the leak was fully repaired.

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation.

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