Ski Resort Crawl Space Restoration – Deming, WA

The Mount Baker Ski Resort contacted us because they knew they had rodent activity in their crawl space. During our comprehensive inspection of the crawl space in the employee housing lodge, our estimator uncovered several underlying issues:

• Mold growth in the crawl space
• Evidence of previous rodent activity
• No foundation vents in the crawl space
• Damaged insulation in the crawl space.

Northwest Crawl Space Services (NWCS) completed the crawl space restoration in about four days, starting with a crawl space cleaning and then replacing the existing crawl space insulation. To address the mold, we applied RMR-86 Pro to eliminate and prevent future mold growth. We also installed four dehumidifiers and encapsulated the crawl space to maintain a dry, healthy environment and prevent future moisture issues.

Crawl Space Services Performed

• Crawl Space Clean and Sanitize: Removed old insulation, vapor barrier, animal feces, nests, carcasses, and debris. Sanitized with a disinfecting mold inhibitor.
• Crawl Space Rodent Exclusion: Sealed all entry points using concrete, steel wire, construction adhesive, and re-screened vents.
• Crawl Space Prescriptive Air Seal: Sealed all air gaps around plumbing, ducting, and electrical wiring penetrations with foam.
• Vapor Barrier Installation: Covered the entire ground area and foundation walls with a 10-mil vapor barrier, securing the edges with stakes and sealing the seams with sealing tape.
• Crawl Space Insulation: Wrapped water supply lines and installed R30 fiberglass batt insulation in the subfloor.
• Mold Treatment: Sprayed RMR-86 Pro® on all wood matter and let it dry for 2-3 days.
• Dehumidifier Installations: The AprilAire E070 dehumidifiers were securely leveled and installed in the crawl space, with internal condensate pumps added for automatic drainage and a condensate drain line routed to the exterior for safe discharge.
