Our Crawl Space Solutions Include

1. Vapor Barriers

Our 7mil reinforced SafeSeal vapor barriers defend your home from moisture. Can be used on both walls and floors for full encapsulation.

2. Protective Wood Sealant

Olshan’s easy-to-apply wood sealant keeps the wood subfloor under your home safe from our wet Gulf Coast climate. It keeps your home safe from wood rot, mold, fungus and water.

3. Water Management

Olshan Drainage systems can be installed both inside the crawl space and on the exterior of the home. Each drainage system is configured to your home and may include EZ drain (interior), pipe & rock (interior), french drains, subsurface drains, downspout extensions, gutters and more.

4. Dehumidifiers

Circulating the nasty, humid air under your home is a great way to improve indoor air quality throughout your home. Dehumidifiers help create a healthier, more pleasant environment.

5. Sump Pumps

Sump pumps discharge standing water from under your pier and beam home. We offer a variety of sump pump options to meet your home’s needs, including battery-backup systems that can operate during power outages.
