"Paul was absolutely fantastic. I had a main sewer line clog backing up into my basement. Paul came out, knew exactly where to access the main line, and cleared the blockage quickly with professional equipment. He pulled out a ton of buildup and completely fixed the issue the right way — not just a temporary patch. On top of that, he was honest, explained everything clearly, and saved me over $400 compared to other plumbing companies told me I would’ve had to pay. Super knowledgeable, efficient, and professional. No upselling, no nonsense — just solid work. If you need a plumber who actually gets the job done, Paul is your guy. Highly recommend and will definitely call him again."

"Needed failed hot water heater replaced. Campbell installed a new replacement the next day after being called. Two installers plus the business owner showed up on time and quickly made the swap. Will definitely use again for plumbing need."

"They are good and prompt, but expensive. Project, replace toilet wax ring. Replace lavatory sink tail piece and lavatory sink stopper assembly I needed this done fairly quickly as the toilet was starting to drip water into a ceiling area below. The telephone staff who set up our appointment were great. Response time was short. Once the technician arrived, he was up front with pricing, so I knew what their price would be. I did postpone other less urgent work because of the price. The cost for these two items was almost $1000. Past experience with other plumbers would have been in the $700 range. However, TMS was available, and they were not If the price had been more in line, I will probably use them as my regular."

Great customer service, Amilcar was always a available when I called. I definitely recommend Diamond Plumbing for your heating, A/C or plumbing work!!"

"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."
