"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! "

"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!!"

"This was not an emergency repair, we were fortunate to be able to schedule the replacement about a week in advance. Heil sent an estimator to look at the space and make a recommendation. We originally wanted a Hybrid system but they advised against it given the space and need to collect/vent moisture. We selected a 75 gallon electric water heater. On the scheduled day, They were on time, removed the old water hearter and installed the new one - professional and courteous the whole time. Unfortunately, the new heater leaked the same day. They returned and made a temporary patch until they could return the next day with a replacement part. They returned, replaced the part and after they left we found that the tank leaked again in another place. They returned the next day and before we could insist that we wanted a different tank (clearly an out of the box failure on this one) they said they would replace the tank which they did. Our first, second and third experiences with Heil were all great with customer service and technical expertise. The inconvenience of multiple extra days without hot water and having to be there for four visits was unexpected and unfortunate however Heil responded correctly and made it right. You can get the measure of a company not only when things go right but also how they respond when things go wrong. We would use them again."

"National water has done a great deal of work for us. When we bought our house in 2001 NWS installed our water purification system any water related needs. I highly recommend them & we will continue to use their services. My husband pays the bills so I'm not sure about the fees but they know what they're doing, professional, friendly & honest."

"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."

"Clayton was understanding of the emergency of replacing the water service pipe since we were without water for several days. I was charged less than some of his competitors might have done. In this emergency situation he was very reasonable, he was reliable and on time and he completed the work in one day. Clayton brought a young man with him to repave the concrete sidewalk and his work was also blemish free. Clayton addressed my question and concerns in a professional manner!"
