I had a problem with water running down my driveway, puddling at the edge of the house, and seeping into the crawl space. Ron recognized that the sidewalk was not pitched correctly and suggested a new sidewalk, correctly pitched, to keep the water away from the house. I was skeptical at first since most contractors recommended a french drain and a rerouting of the gutters to solve the problem. The test of the new sidewalk was the next heavy rainstorm. It worked! No more damp smell in my basement! Thank you, Ron!
