My water heater suddenly broke. I called Shawn's plumbing. He came out that day to assess the…read moresituation. He was back the next morning at 10 AM with a new water heater. Installed everything by 1 PM. I had a shower by 130. Less than 24 hours later I was all set. Very competitive pricing. My basement was not easy to get in through the bulkhead and he managed to get everything in Shawn was professional, courteous, reasonable prices. I definitely recommend.

I called Joyce regarding a slow leak in my main water shutoff valve. Joey and Will arrived ahead of…read moreschedule, and I showed them where the leak was. They completed the work in short order. While they were working, they noticed the smell of gas and investigated it. Using a gas sniffer, they found the leak. It was from work that another company had completed on a tankless water heater months earlier. The repair became difficult, requiring them to shut off the gas, contact their supervisor, and Liberty Utilities. Joyce completed the repair. Liberty checked the house for gas and turned the gas back on in the house. Joyce went above and beyond for this water leak. I recommend them for any service they support.

During the 2023 polar vortex, at 1AM of course, our plumbing pipe burst sending water along the…read morewalls down 2 flights. Luckily we were home and cut the main water off but needed a plumber first thing in the morning on a Sunday. We were striking out. No calls back. Voicemails upon voicemails to several companies and local plumbers. We were fairly new to the home and area and did not establish any plumbing service with anyone. Some companies were only responding to established customers first. We found several people on social media (FB) had recommended David's Plumbing on local community pages. We gave it a try. He picked up but you can tell he was moving from job site to job site. He squeezed in a visit to our home that same day in the early afternoon. The pipe ran along a very poorly insulated and tight crawl space. In about an hour, the pipe was repaired. He released the air and pressure from the entire system. He examined the basement and the system. He tested and ensured all worked properly. David was kind, knowledgeable, and professional. He showed up in his company vehicle with everything needed to complete the job on site. We found his rate to be extremely reasonable given the repair, the location of the burst-pipe, and the same-day service call. We highly recommend David Plumbing and will be using him moving forward for all our plumbing needs. He is fully licensed and certified.
