Before and After Pictures from Keizer
Crawl Space Encapsulation in Keizer, OR

Crawl Space Encapsulation in Keizer, OR

Before After
Crawl Space Encapsulation in Keizer, OR Crawl Space Encapsulation in Keizer, OR

This Keizer crawl space had seen its fair share of rough winters and heavy rains. Year after year, this crawl would be holding in rainwater, and eventually, mold was starting to produce.

Our System Design Specialist, Mike O'Brien, quickly scheduled an appointment with the homeowner as soon as they called TerraFirma. After spending more than an hour in the crawl space, he concluded that to prevent water damage; the area would need to be encapsulated with drain tile, and 120 mil thick VaporLoc Elite liner.

Along with encapsulating more than 1,000 square feet, Production Foreman Brad Peterson and his crew also removed the old, wet, and mildew-ridden insulation that was doing more harm than good.
