"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!"

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."

"My tankless hot water heater was dripping and it was a weekend. I received a text message from Ensor. I sent her a picture of the part the was dripping. She looked it up and tracked down the part at a store over an hour away. She came over immediately and her partner arrived a few minutes later with the part. They installed it quickly. Excellent customer service!"

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"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."

"James did multiple jobs for me after diagnosing the actual problem. Correcting the issue required james to replace part of an old pipe which could only be accessed through a ceiling. James not only fixed the plumbing issue, he completed the carpentry work and repaired the ceiling. He also replaced my shower floor and the tiles surrounding it. James also replaced faucets on my utility sink. James is exceptionally knowledgeable, professional, and a master of his craft. I highly recommend hiring him for your plumbing needs and wants."

"Eric was very responsive. It was a long process, but we now have great pressure in both faucets and can regulate the temperature! Eric worked through our problems and came up with good solutions."
