EXCELLENT Based on 139 reviews Rudiger Bieler2025-04-06Trustindex verifies that the original source of the review is Google. Water heater issues: Quick response -- fast and friendly service. Highly recommended. Britt Calvert2025-04-04Trustindex verifies that the original source of the review is Google. We had flooding in our basement and after calling Demmis around 9AM, we had a flood free basement by noon. Truly could not be more impressed with their responsiveness, professionalism and knowledge -- not to mention they let us know how we can (easily!) avoid the problem in the future. Will be using them for all of our future plumbing needs! CA Hearne2025-03-28Trustindex verifies that the original source of the review is Google. Had a leaking drain line downstairs, called late in the day. The plumber arrived early the next morning, was very friendly, explained the fix and went to get the parts. He had problems with securing parts, but with all the problems did a SUPER job fixing my problem. I would definitely call them in the future. R C2025-03-27Trustindex verifies that the original source of the review is Google. We have used Demmis Plumbing on two occasions and will continue to call them for every plumbing issue here on out. Extremely respectful, reliable, and trustworthy family owned business. They helped us unclog our sewer line from baby wipes and most recently replaced our hot water tank. Both services were completed same day and efficiently. Being a stay at home mom, it is always intimidating having someone come work in our home while my husband is not around but Demmis Plumbing has always made me feel comfortable and as if they’re friends or family. They answer any and all questions while providing you with honest feedback and high quality work. They’re not sales men, they’re top of the line plumbers ready to fix the job and that can be hard to find these days. Cannot recommend them enough!!!! diana sinickiene2025-03-20Trustindex verifies that the original source of the review is Google. I’ve been using Demmis Plumbing for years, and they’re my first call for everything—clogged sinks, leaky faucets, and even bigger plumbing repairs. Most recently, Dan came by to fix a slow-draining sink in my bathroom. He found and cleared a clog deep in the pipes, replaced a worn-out seal, and made sure the drain was working perfectly. What I love about Dan is that he always explains what he’s doing and gives helpful tips to avoid similar problems in the future. Whether it’s a small repair or a major job, Demmis Plumbing always delivers reliable, professional service at fair prices. I can’t recommend them enough! Mrs. G2025-02-04Trustindex verifies that the original source of the review is Google. I noticed that my water heater was leaking alot of water.

Thank you for your quick response Joe Crowley2025-01-30Trustindex verifies that the original source of the review is Google. Our sewer line failed on a Sunday morning. Called Demmis and they had someone out within 20 mins. They got us back online that day and repaired the issue in timely manner. Very professional and friendly. Would recommend to anyone looking for good plumber. Shana2025-01-20Trustindex verifies that the original source of the review is Google. Very fast service! I've used Demmis twice now and they were here quick! Reliable and friendly company. Will use again.
