Water heaters, boilers and household plumbing repairs bring customers to Douglas Plumbing & Heating in Farmington. In June 2026, a customer praised Doug’s quoting and scheduling and Ray’s installation of a pressure-reducing valve and expansion tank. Another June customer described Dean and Dylon explaining the options before a repair, answering questions and leaving the area clean. Google shows a 4.3-star average from 45 ratings, and the company’s Connecticut plumbing license is active. Several customers describe returning over many years. A December 2025 reviewer said they had used Douglas for more than thirteen years and had just had a gas furnace replaced. A February 2025 reviewer described two plumbing visits and praised Dean’s explanations. In August 2024, a customer said a replacement boiler was ordered and installed within a week; Douglas later reminded them about inspection, and the reviewer said the inspector was pleased with the installation. Urgent response has also earned praise. A February 2026 customer said they called on Saturday about a failing water heater and had a replacement installed Monday. A January 2023 reviewer described same-day water-heater repair. These accounts sit alongside a serious April 2026 complaint: a homeowner said a clamp replacement made a basement leak much worse, the technician shut off the water and left without resolving it, and both the technician and owner handled the conversation poorly. Prices draw differing reactions. A February 2023 reviewer reported paying $320 for water-heater diagnosis without a repair, then receiving a further $122 bill after canceling a part order. A January 2022 customer praised the work but objected to the price and said a request to discuss it went unanswered. Other customers, including the June 2026 repair customer, described reasonable pricing. BuildZoom lists a separate Connecticut home improvement registration number for the company.
Doug and Ray were a pleasure to work with! Had called to get a quote on a pressure reducing valve and expansion tank plus install. The whole process was a great experience, from getting a quote to scheduling and installation. Ray did an excellent job on the install and explaining everything about the work. I will definitely be giving Doug a call if I need anymore work done in the future.
I had such an excellent experience with DPH from start to finish. They responded quickly, arrived on time, and clearly explained the issue and the available options before beginning any work. Dean and Dylon were professional, knowledgeable, and took the time to answer all of my questions. The repair was completed efficiently, and everything was left clean and tidy afterward. The service was reliable, professional, and reasonably priced. I would highly recommend them to anyone looking for quality plumbing services, and will definitely use them again in the future. 5+ stars!
