"SwiftPro was excellent. When our hot water heater went out (at nearly 20 years old, we were neither upset nor surprised!) we reached out to a few places but SwiftPro was the most responsive and had the price was fair. Zabi, the service technician was fantastic. I can’t say enough good things about him. He was prompt, provided excellent communication, took meticulous care with the work and work space, and was just a great person to talk to. The install went great and there was no aggressive sales tactics or upselling. Just a genuine cut and dry hot water heater removal and install experience. I highly recommend SwiftPro. Thanks Zabi!"

"I can't say enough about DB's Plumbing. I called in the morning, had a return call within hours and they were at my house that night. 24 hours later, the new hot water heater was installed! Price beat all others. Duncan was professional and knew exactly what he was doing. DB Plumbing is now my GO TO PLUMBER!"

"Albert and Joseph provided truly exceptional service during their visit to my home. Albert first installed my kitchen faucet and food processor, and then, both came back to install a water heater with remarkable professionalism, care, and efficiency. From the moment they arrived, they were responsive, respectful, and incredibly warm. They took the time to explain my options, helped me feel at ease, and ensured I understood why the water heater they recommended was the best choice on the market. On top of that, they went above and beyond by fixing a separate issue in my shower without hesitation. Their dedication, expertise, and kindness made the entire experience outstanding. I am deeply grateful for their work and highly recommend them."

"Woke up to no water and quickly figured it was a bad well pump. Called Tommy at 6:15 am and he came over to access the problem. Went to plumbing supply and gave us options on pumps. Installed same day and water is running. Very knowledgable and quick to respond!"

"A+++++ Service. 5 Stars for sure. You should definitely check them out. I am so glad I've taken my time to find good, honest, trustable and fair plumbing company, and I finally found this R-Plumber company. A few months ago, my place had a water leak in the shower on upstairs bathroom and it caused ceiling damage, etc. so I needed to a ceiling drywall repair, bathroom tile repair, CPVC pipes reconnect, water pressure reducer install, etc. I took my time to compare various popular local plumbing companies in the DMV area and this is, by far, the best I've found due to many reasons: 1. They are licensed, bond, and insured -- They sent me a copy of their license, bond, insurance, and worker compensation. This gave me a relief because I wanted to make sure I hire a professional. You'll need it in case if anything happens. 2. They really care about you and HONEST -- Rene, Luis, his apprentice, and other staff use the best brand and told ,e really honest and professional opinion. I have a limited budget and they told me I can just fix the issue for now. The other companies recommended me to remodel the whole bathroom, which would cost at least $4,000 or much more. 3. Their price is VERY REASONABLE and FAIR -- They do not overcharge at all in compare to other companies in this area. I compared 6 other plumbing companies. Other plumbing companies seem to take advantage of you especially if you don't really know much about plumbing. They either: - could only offer to fix the plumbing and I had to find my other contractor to repair the tiles and dry wall - offer me to fix this issue for $4,500 or more - R Plumber offer me about 40-50% less than other companies. - another well known company (they were featured in local Costco) gave me a price to fix my sink popup assembly for about $700 but I went to home depot and bought the parts myself for $17. 4. They really guarantee that they carry their work by the correct local regulations and to the high standard. -- you can see the photos for reference. - I ASKED them a lot of questions and researched the way they do they work online and everything seems to be done very correctly (e.g., using the right glue, chemical for connecting my CPVC pipes, copper pipes) - They went above and beyond in installing my water pressure reducing pipe by anchoring my water supply pipes so it doesn't get shaky. - They have 1 year labor warranty. Their shower MOAN is lifetime warranty on parts. In fact, I am so impressed that I literary have to write my appreciation on various social media in a hope to help others who are in the same situation as me. This company doesn't spend on marketing but just spend on high quality so I'm really trying to help get this company to top review to help others who are in the same boat. Best wishes to you guys who are looking for a good plumbing company. This is some company you should consider."

"Called Dexter Wells & Plumbing and John was about to come out the same day and the very next day installed a new well pump and pressure tank for us. We are very pleased with the services received. John is a very nice man and definitely knows what he is talking about when it came to our issue. Would without a doubt recommend them and use them again."

"I found water on the floor of my basement! Horrors! I got 3 estimates and chose T.QEXCAVATION.Plumbing to do the fix. I liked the work ethic of Terence, the owner who was the guy who did the job. He kept me informed of what was happening and how the project was going, turned the water on when he could and off when he needed to so I had water off and on instead of not which meant the world to me. The job is done, I'm happy with the result and would recommend T.QEXCAVATION.PLUMBING to anyone in need of any kind of plumbing job. He is my plumber from now on."

"The original project I hired them for was to replace leaky faucets in both the kitchen and bathroom. Frank, the owner, was responsive and professional. They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."
