I've used Colburn 4 times now and have a great experience all 4 times. They installed my water softener, installed my kitchen sink, replaced my water heater, and just now attempted to find a leak from my attic. They were unable to detect the leak, but were able to direct me to another company who has the tools to find the leak and did this without charging me. They are as ethical as any company you'll find. It's why they'll always be my first call when I have a plumbing issue.
