The retaining wall they built is fantastic—strong structure and immaculate finish. Friendly crew who really know their trade.

The attention to detail on the retaining wall was second to none. They left the area cleaner than when they started – lovely touch.

I asked Keystone to take a look at a retaining wall that had some cracks throughout. Luis showed up on time and gave us his very honest opinion that the cracks were not jeopardizing the structural integrity of the wall and, in his opinion, nothing needed to be done. I appreciated his expertise and the fact that he didn't try to sell us on on a service that was not needed. I will definitely call him in the future if there is ever a need.
