John was fantastic, courteous and very accomodating. I needed my project split into two parts, and he was more than willing to work with me to get the job done! He is very knowledgeable, and explains things without talking down, or over your head. Very hard worker and quality job done! Thanks John! (and Chris too!)

John came, gave estimate (way inside the ballpark) came when he said he would. Did the job. Wife is extremely happy. Didn't have to clean up after him. Works great. All should be like him.

John and Chris were very professional, thorough, and polite. Very happy with the heater installation and clean up was excellent. After 3 prior estimates, theirs was the best. I would definitely hire J&K again!

J&K turned out to be the ultimate service provider for this residential basement sump pump improvement. They explained everything in detail and offered different options with precise price estimates. We interviewed several other plumbers and they didn't come close. Most important, they completed the job quicky and efficiently. The best home service imaginable. A+. 100%
