"I've had work done many years ago, where the work done by people that were not as professional as Jimmy would only last a few years - all the work he has done has been fabulous, reasonable in price. The work up here has to be done in a special way, and his has been fantastic with how long it has lasted. I am very happy, he has done some special things for us to get the prices as low as possible. If we had somebody else do it, it would probably cost twice as much."

Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.
