Crawl Space Encapsulation in Tualatin, OR

Crawl Space Encapsulation in Tualatin, OR Crawl Space Encapsulation in Tualatin, OR

This Tualatin crawl space was riddled with groundwater that was producing high humidity and mold throughout the area. Eventually, the mold and humidity made it up to the first floor of the home. Once that happened, the homeowner did the right thing and gave TerraFirma a call!

Our System Design Specialist quickly came to evaluate the situation. He concluded that the crawl space would need a TripleSafe Sump Pump and complete crawl space encapsulation that included removing the wet, mildewy insulation that was harming the home's air quality. With a plan set, our production crew went out and completed the job in three days!

Our VaporLoc Elite encapsulation reduces musty smells and an EVOH layer that seals out odors. VaporLoc Elite is a 120 mil thick liner that insulates your crawl space and reduces energy costs. Along with reducing allergens in your home, your newly encapsulated crawl space also gives you a clean, dry, sanitary usable storage area.

Water entering SW vent (there is a vent well) into crawlspace. Need other vents inspected for possible water entry and vent wells installed in some areas. Insulation is sagging in areas. Smell coming from vents due to water in crawlspace area. There is a low point drain in crawlspace so water does eventually drain away. Crawlspace does have vapor barrier. Need a few of the vent screens repaired and insulation replaced in area that it's failing. Additional information: How did you hear about us: Other Main Area of Concern: Crawl Space
