"Saved by Ehrhardt Brothers Quality Plumbing (a.k.a ColumbiaPlumber)! (West of Baltimore) Our gas water-heater failed! It’s 30° outside! (Mar 2026). It was leaking, so we shut off the gas, the pilot, and the water inlet, to lessen damage if it burst. Ehrhardt offered a price based on our descriptions and photos, of course with caveats for anything unexpected. A water-heater costs a pretty-penny, but less than we expected. A fair price. They came the next morning, and had the water heater replaced in 90min. Impressive. But the manufacturer sent a unit with a bad pilot! Ehrhardt returned immediately and in 30min, they figured it out. They had a replacement part over-nighted. The next morning, in 30min, done. Hot water. AAAAAHHH :-) The problem was the manufacturer’s fault, and Ehrhardt handled it flawlessly: Excellent communication by Ehrhardt, priority attention to our problem, no excuses, just fast resolution. Great service staff. Perfect!"

"Dominic Cantor arrived on time and went straight to work replacing the toilet spanner flange and re-installing my toilet. He was able to make a temp repair to the broken chain in the tank. He was very professional and conducted several tests to insure that there were no leaks when the toilet was flushed."

"Sila was excellent to wok with. They had the experience and knowledge, plus a competitive price and financing options. Their installation crew was very good to work with - respectful of the house interiors, and cleaned up everything inside and outside. Also asked the appropriate questions when any installation matter offered a choice."
