We used this company to repair a leaky backflow valve in our community.
1. They did poor work. (leak returned shortly after being fixed, the concrete anchor was not embedded into the concrete, the concrete around the anchor was only a couple inches wide, the surface was completely rough, etc.)
2. They did incomplete work. (left the job site before done and didn't come back until multiple calls were placed over several weeks' time, the valve was out in the open unprotected this whole time)
3. They made the existing condition worse. They modified the design of our security cage in a fashion that it would be impossible to open (without damaging something). When they "fixed it" they made it very easy to break into and steal the valve (which has happened twice previously).
4. They failed to meet commitments (several times they said they would complete work by x time, and it was not done as promised)
5. They failed to follow instructions. They were requested to repair the security cage so that it was configured the way it was when they started on the project. They are apparently incapable of completing this request.
6. They failed make things right in the end.
Use these folks at your own risk!
