Job Stories From Sequim, WA
Discovery Bay Historical Home

Customer Jim M. called our office interested in upgrading the vapor barrier in his historically significant residence in the Discovery Bay area.  The home was originally constructed as part of a small Naval Station that existed years ago.

We provided the customer with some options and he selected the CleanSpace encapsulation system over drainage matting to insure the longevity of an already old well maintained structure. The building was built with masonry stone and brick piers which made for some interesting detail work for our crew.
