"Needed to have my water heater replaced. Joe and Sam came out that day to remove my old one and install a new one. Very friendly, knowledgeable, and helpful! I will definitely use them again with any of my plumbing issues in the future. The price was right inline with what I was expecting."

"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."

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

"Hired Mahon Plumbing to replace a toilet at my moms house. Chris and the technician were knowledgeable and responsive. I had a great experience working with them and would hire for any future needs."

"Sam and Chad did a wonderful job clearing the tub drain, installing new faucets in the bathrooms, installing a new shower head, and other projects. They double checked their work and answered any questions I had. While they need to come back next week to do a small part of the whole project, they were honest about what piece of equipment they thought would work, but would not. They were efficient, professional, and pleasant to be around. They made my day."

"I originally called Third Generation to give me a quote on a partial master bath remodel. Robert and Christina came to the house together and gave me some good advice on what needed to be done and a ballpark figure for the work. They also explained that they flipped houses and had trusted people who could do whatever else I wanted to have done in the house and could do it fast. Shortly thereafter, my circumstances changed and I decided to do a full master bath gut and remodel along with a long list of things I had wanted or needed to do for years. Robert gave what I considered a fair quote for my VERY long list of jobs and had people on site within days of signing the contract. Everyone working the job was pleasant, hard-working, and highly skilled. I felt very comfortable with all of them and had no reservations about having them in my house when I wasn't there. The whole job took about 8 weeks but 2 to 3 weeks of that was because a special-order vanity arrived damaged and had to be re-ordered, delaying the completion of the new master bath. I am delighted with the job(s) done by Third Generation. My master bath is gorgeous, my laundry room is now attractive instead of an eyesore, and a long list of "I hate that"s has been turned into "I love that"s. For the amount of work I had done and the range of different types of work involved, the speed of completion, even with the delay caused by the defective vanity, was really impressive. I will definitely call Third Generation again not only for plumbing work, but for future remodeling that I may decide to do. This was a great experience and I have no hesitation in recommending Third Generation."

"Andrew and his team were great from start to finish. He was able to match pricing, which initially was a concern, and the speed and quality of installation has been more than worth it... The installed system has been working flawlessly especially as the temperatures started dropping. I will definitely use them again, and at other locations. Andrew is very knowledgeable, easy to talk with and ask questions, and a perfectionist at what he does.. this quality-oriented approach really shines through and makes Amazing Heating & Air stand out high above the competition."
