My water bill was extremely high and I knew I had a leak some where in the house. I gave checkered flag plumbing a call, after reading there reviews on the internet. The plumbers came out located the leak and fixed it an a matter of hours. I'm very happy customer and would refer them to everyone.

great company I have been using for a couple of years now after finding them on a special ad and giving them a try. Needless to say they are great and have helped me in many situations now in my home and my rental home.
I have had them replace the original water heater in my home from 30 years ago. I have had them change faucets and make numerous repairs in my rental that unfortunately a tenant did some damage, but my Checkered Flag Plumber saved it for me.
I am pleased with this company and ill continue to use and recommend them.
