"Faced with a very serious old stone foundation problem, it quickly became clear to me that most contractors I spoke to actually had no idea what the best course of action was. Luckily, through The Mended Wall website, I found Andrew Spielberger. As soon as he came over, I immediately sensed that he knew exactly what he was doing. He proceeded to do a beautiful job on a very challenging situation and came in right at his original estimate. Andrew is deeply knowledgeable, incredibly versatile, meticulous, and the kind of great craftsman who hardly exists anymore. I recommend him without reservation; you will not be disappointed.

A very satisfied customer in Cheshire County"
