Bob was always professional, there were no hidden costs, and Gradex is a company that we trust and respect. We have a second project that we plan to embark upon shortly and Gradex and Bob are our choice.

Bob was up front with pricing, clear about construction time frame, and delivered exactly what was agreed upon. He was by far one of the most outstanding parts of our home construction.

Bob Kerr and his team are a welcomed relief from most contractor experiences – honest, on price and on time. And the work is simply outstanding. I’ve already passed his name along to a number of friends and neighbors. I’ll be calling Bob if I have any jobs in the future.
