Get matched with top tankless water heater repair pros in Silver Spring, 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."

"Exceeded our expectations! I called at 12:30 on a Saturday about a leak in our basement. He was there by 3:00. Found it was our toilet on the first floor. He fixed it all quickly and efficiently. Explained in detail what happened and why it happened. Even explained the hum we hear in the house when the water turns off. Even liked our dog Bruno!"

"Kap did a great job all around. I originally had him come out to assess why the water heater wasn't working (no hot water). He determined that the unit (15 years old) needed to be replaced. He also pointed out that the system is not up to code and some extra work would be required. I asked if he would be able to do the new install and asked if he could do it sooner than later, as cold showers for days (even one more) would not be fun. He ended up coming back out same day - about 6pm - with all parts and the new unit. He stayed until 11pm! to get the job done. Kap is fantastic. He's knowledgeable, professional, and very nice person. Highly recommend."

"Within 24 hours of my posting the need to replace my water heater the work was done - very efficient and easy!"

"Called the main number and the lady I spoke with was very pleasant and easy to work with. Was looking to have a 50 gallon hot water heater installed, 2 drains snaked and a new faucet installed. She booked my appt for the next day. Zam came to the house to provide us the quote and even offered to do half the job then and come back in a few days to do the hot water heater. He was incredibly professional and did a great job on all the work. I highly recommend them and will call them again."

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"Hired Pohlman to evaluate two natural gas tank water heaters in our home, one of which was unoperational. They suggested combi-boiler for our home in lieu of two tank water heaters. They did a great job and we are very pleased. Customer service is top notch, and I highly recommend Pohlman Plumbing."

"Our water heater died, and was leaking. We called after hours, and owner answered the phone. Technician came out next day, and he showed up on time and replaced the heater. Plumber was very courteous, professional, and helpful with advice. No complaints - work is guaranteed. Only downside: price for the water heater itself was high - could have bought comparable unit much cheaper at HD or Sears, but would then have needed to have it delivered and installed by the plumber anyway. Their work is was very good, which was most important and we would definitely use them again."
