I had the pleasure of meeting Jean. He was very professional and courteous. I had a very complicated and odd issue with my plumbing and he completed the job in no time. He was so fast and fix the issue right away. Hands down one of the greatest services I’ve had. He will forever be my guy if we need anything done. It is so hard to find someone you can trust nowadays. And I am so happy to have found Jean. Thank you Jean and GNK plumbing and heating!

Jean of GNK was a wonderful plumber. He was extremely responsive to our request for service. He replumbed the ancient pipes in our basement and installed a new laundry room tub and sink. He also installed a new toilet in our basement. He was fast efficient and pleasant; the work only took 1/2 a day or 4 hrs. We would definitely hire this company for our plumbing needs in the future.

Details: A few pipes • Other plumbing installation or replacement • Hook-up appliance or fixture • Other pipe installation • House
