Brian came to provide an estimate for preventing a leak in our basement. I thought we had a leak through the foundation. After about a half hour of investigating Brian discovered we actually had a leak in a pipe that was difficult to see. He ended up saving us several thousand dollars while not completing a sale for CtBS. However, he did "sell us" on the integrity of CtBS. Although I can't vouch for their workmanship I can for their honesty.
