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!
