"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!"

"Tommy was professional and knowledgeable. He arrived at both appointments on time and got the valve and water heater replaced quickly. I would highly recommend them. I comparison shopped two other plumbing companies during the day and DB's was the best in knowledge and price."

"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."

"I had to replace a water heater quickly. Gave me a competitive quote with a water heater with desirable specs within a day and scheduled me the day after. Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"Rene, the owner of R-Plumber arrived on time for a Saturday project evaluation and did a thorough professional review. He offered reasonable suggestions about the scope of work, and noted that two of the apparent problems were actually not in need of repair. He was immediately likeable, and although his cost estimate was in the middle I hired him. His assistant Luis worked well through the day, doing a great job on the water heater and disposal install, and although the 45 year-old bathtub faucet replacements took a lot more work than expected there was no complaint or request for additional money. I will use him for future plumbing needs."
