Get matched with top tankless water heater installers in Spencerville, MD

"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!"

"Excellent. Two separate teams came; one for AC and Furnace; second for Tankless hot water heater; Minor toilet repair also done at no extra charge, including a follow up service call to install new toilet flush handle, also at no charge."

"Fred was responsive (same day), courteous and professional, got to work immediately and was quick and efficient.  He gave me thoughtful advice as well regarding getting maximum life out of my appliances-I solicited him on replacing my water heater vs the other way around.  Pricing was very reasonable.  Highly recommend.

"Could not have asked for better service. The recommended product is working great, the installers were professional and so far the service technicians are top notch."

"Mr. Rema arrived on time Sunday morning to update my water heater. He installed an expansion tank, duct work and replacing the piping to the thermostat on the water heater. He did an excellent job and took his time. Mr. Rema also went to the local hardware store twice to pick up the material that was needed. The only reason I didn't give him an A was because he quoted me a price at the beginning and then went done on the price and then tried to go back up to the original quoted price. After talking with him he decided to keep the price at the lower amount that he quoted."

"Kan and Puia arrived the same day as my call and completed an evaluation of services needed, in my case mostly a replacement hot water heater. They came back the next morning, put down drop cloths, did the work and made a suggestion for something that needed attention that we hadn't noticed. Very pleasant people to work with. Work was completed in good time with great attention to detail at a good price. It's good to have Kan in my contacts. I will definitely call him in the future. Thanks, Kan!"

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Tried to push me into purchasing a new water heater and quoted me higher price based on estimate from their affiliated company (which had accidentally quoted me wrong price initially)."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."

"Fantastic company. We had a water heater installed. The installer was fantastic. He was on time, professional and extremely knowledgeable. We will use them again. If I could give them 10 stars I would.."
