In this basement, moisture was seeping through the walls, causing the paneling to warp and mold to grow. As a result of the moisture damage and mold growth, the walls and carpet had to be removed and the area treated for mold. Drilled-in fasteners are used to attach BrightWall to the walls, a 100% waterproof, washable, and high-durable rigid plastic sheeting. By blocking vapors from passing through the walls, BrightWall prevents mold growth and rot. Additionally, it gives the space a brighter appearance. Thus, BrightWall is a great choice when it comes to protecting walls from moisture and mold.

Job Stories From Allison Park, PA
Waterproof Basement Wall Panels in Allison Park, PA

A basement in Allison Park, PA fell victim to moisture problems that led to mold growth, musty odors, and structural damage. After providing the homeowner with a free inspection, we recommended a solution that would solve the problem permanently. Our solution was a comprehensive mold remediation process that involved removing the mold, treating the affected area, installing an interior perimeter drainage system, installing a high-quality sump pump, and because of the extensive damage caused by the moisture, the basement walls had to be removed and BrightWall Basement Wall Panels were mechanically attached. All of these steps were necessary in order to create a safe, dry, and healthy environment for the homeowners.

Basement Waterproofing in Allison Park, PA

The homeowners had a leaking basement that they wanted to have professionally addressed.  We sent out our most seasoned inspector, Mr. Kelly Blackburn, to assess the foundation to see what was required to fix the foundation permanently.  After his site visit, a scope of work was presented and the homeowners put their trust in Keystone.  


Our foreman, Mr. Brad Stone, installed the internal waterproofing system and the homeowners were very impressed.  In addition to leaving a public review of the work, they mentioned Brad by name.
