Kurtis and Nolan were very helpful with running my new utility lines (Gas, Sewer, and Water Supply) for my future outdoor kitchen. Since I was pulling permits, there were certain plumbing codes to follow. Kurtis was able to figure everything out and both gentlemen did an exceptional job; even the inspector was happy.
I highly recommend the folks at KDP Plumbing; they are true professionals and will take care of you from start to finish!
Price assessment: Reasonable price
Response from the owner · a month ago
Passing inspection smoothly on new utility lines for an outdoor kitchen takes precision. We are glad Kurtis and Nolan delivered that exact standard for your gas, sewer, and water supply project!

Amazing service. I had a very complicated and difficult issue with my outside drains. About 50 feet of root clogged the drain. Kurt and his team worked tirelessly for 2 days and was able to resolve the problem. Very appreciative.
Response from the owner · a month ago
F F, tackling 50 feet of invasive roots in an outside drain is certainly a challenge! Kurt and the crew were glad to put in the hard work over those two days to get your drainage flowing properly again.
