"Called Modern Plumbing Systems (based on a NextDoor recommendation) to install a new hot water heater and sump pump and couldnâ t be more pleased. Bryan, the owner, was the consummate professional â immediately returned my phone call, checked on all available options for my specific system and needs, thoroughly explained each option to me, provided an immediate quote based on photos I sent, and then did a great job on the install of both the hot water heater and the sump pump. I would highly recommend him to anyone in the market for a new hot water heater, or any other plumbing needs for that matter. Super satisfied and would absolutely hire him again!!"

"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!"

"Well let me start by saying I called several water heater companies to inquire about an estimate for my hot water heater that was not getting real hot. He was the ONLY repair person to come out that gave me the feeling he was trying to fix my hot water heater and not trying to sale me a new hot water. I never had a hot water heater water heater issue before therefore i was not familar with pontential problems. Everbody tried to get me to buy something called elements without actually trying to fix my heater. Wallace plumbing was able to identify some pressure thing or something with the thermostat that he fixed and saved me pontially thousands of dollars that other companies tried to sales pitch me. I then called Wallace plumbing because my toliet kept running and Wallace came out and fixed my toliet in minutes and his prices are very affordable. I will be using Wallace plumbing for any future needs and I recommend them!"

"Tess was exceptional. he replaced a leaking old water heater. When I made the call, he was on another job but since water was leaking he came later that evening to address the leakage. He was respectful and hardworking. He came on time and finished the job on time, the project was top notch. His price was very reasonable compared to others."

"Fritz B. was my sales rep and he clearly knew what he was doing, including making a few minor recommendations that were in my financial interest. Easy to set up the scope of work. The grew was great, came in and did a great job, took about 6 hours. They even rerouted the exhaust flue for my hot water heater even though they did not replace the heater because the install guy Chris said "they did this dumb". Overall a great experience and I would recommend."

"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!!"

"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."

"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."

"Installation went very well. Oct 25: Rob Figliozzi came out to evaluate the work needed and brought two workers to install the sink faucet and drain/trap. He determined what parts were needed for the tub/shower and ordered the parts. He texted me when the parts came in 3 days later and Chris Hanes came out to install. Chris is a very pleasant young man and did a great job with the installation, and Rob was very helpful and responsive. Highly recommend."

"Brandon identified and isolated the water leak immediately. His expertise and speed were unmatched."
