"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!"

"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."

"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

"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"

"Prime Plumbing provided excellent customers service from the beginning to the end. Rob was very thorough when he came out to provide estimate, financing options and gave good explanation of what was needed to replace my direct vent hot water tank for my condo. Rob was also the one who installed the hot water tank and did an excellent job. Direct vent hot water tanks are much more expensive than your standard hot water tank, so it was pricey. I initially found Prime Plumbing on Angie's list and I would recommend them for your plumbing needs. I'm a single female in my early 60's. I did end up using my own financing because their finance company interest rates were way too high for someone with excellent credit. Do rate comparison first."

"My girlfriend called me to tell me she had just got home and there was water on the floor.  I went straight home and found the water heater leaking.  I called Bamford Plumbing and spoke to a lady who asked several questions concerning the the tank number and approximate age (in case it was still under warrenty) and she took my phone number and said she would call me right back with an estimate.  Roughly 4 minutes later she called me back to give me an estimate and unfortunately to tell me that they couldn't be out until the next afternoon.  She recommende several other plumbers in my area and said she would hold the apointment just in case I couldn't get someone out sooner.  Well I called Heidler and was told someone would call me back.  45 minutes later a technician called and said he would be out and it would cost $185.  I asked what the charge was for and he said to look at what was leaking!  I explained it was the water heater leaking and I had turned the water off to the heater at this point and he said he could come out and cut the line to the water heater for $185 and there was nothing else he could do since it was after 4pm.  Again I said I had turned the water off and to have a good night.  I called Bamford back and told the lady I wanted to keep the appointment and told her what Heidler had said and she was shocked and appologized for what had happened and suggesting them as someone to call.
I received a call from Bamford in the morning to give me an approximate arrival time.  They arrived in the early afternoon as promised and replaced my water heater and necessary fitting.  They also had to install a inline preassure tank as required by Anne Arundel county, since there wasn't one at no additional charge. 
Overall an outstanding and professional business!

"We purchased a house and adding a whole house water filter was on our list. Our local Orbit dealer performed a free water test and confirmed a that a lot of the junk we had read was in our city water was in fact there. Our previous house also had hard water and we saw firsthand what it did to our pipes and hot water tank. Plus we were tired of a filtered water pitcher taking up space in our refrigerator. Our sales person went over all of the features of the Puronics 7000 system and outlined the maintenance which simple and easy to understand. Installation took place about two weeks later and the guys were done in a day. About a year out and we're still very happy with the improved water quality and the system itself works great."
