We were out of state over the holiday weekend and our heat wasn't working. The forecast was for very frigid cold weather. Dennomee plumbing was able to provide a tech same day, kept us informed on arrival time and committed to solving the problem. Very fair and honest and shared complete diagnostic testing results and next steps. Within a few hours they were able to resolve the issue and get our heat working again.

Had mistaken a dog chew for dog poop and flushed it into my up flushing macerator basement toilet. Well, it jammed the macerator. I called denomme and within 1 hour Nick and Mark came to my house and fixed it. This was a 7pm call, 8pm arrival, and I was anxious as heck as my multiple attempts to flush just created more backflow and rising water in my toilet and tub. They assured me they'd take care of it and explained the contingency plan if it didn't work. We had a few laughs and Nick and Mark were amazingly professional and a joy to be around in that stressful moment. Thank you so much!

The technician was on time and was very knowledgeable. He assessed the issue and was able to get my heat running in short order. He was up front and clear as to what he had to do as well as gave me a quote for suggested service in the future. There was zero sales pressure on the suggested topics.
Would definitely use them again if needed.
