Dry First, Then Finish

A finished basement is only as good as what is behind the drywall. Before we frame, we look for signs of moisture, check grading and downspouts, and plan insulation and vapor control for Maryland’s humid summers. If there is a water problem, we tell you before you spend money on finishes.
