From initial MC% assessment through borate treatment and vapor barrier replacement to post-remediation clearance — the full below-grade mold scope in one place.
Assessment
🔍MC% Assessment & Contamination Mapping
MC readings at 10–12 ft intervals across the crawl space. Visible growth mapped and photographed. Written assessment with findings before scope proposal.
Removal
🔨HEPA Removal & Wire-Brush Treatment
HEPA vacuum and wire brush on all contaminated surfaces. Spore material captured during removal — not disturbed into the crawl space airspace.
Treatment
🌳Penetrating Borate Application
EPA-registered penetrating borate solution applied to all accessible joist and sheathing surfaces after HEPA removal. Borate diffuses into wood fiber over time, providing ongoing inhibition of fungal colonization — including species that may not be visually apparent yet. Borate remains active in treated wood for years.
Structure
🔨Sistering Structurally Compromised Joists
Joists with advanced fungal digestion — evidenced by delamination of sheathing, spongy or punky texture, or through-penetration of decay fungi — lose structural capacity and need sistering with pressure-treated lumber rather than treatment. We assess each joist individually and document replacement recommendations in the written scope.
Barrier
💧Vapor Barrier Repair or Replacement
Reinforced poly, correctly lapped, footing-secured. Proper vapor barrier installation is the #1 long-term prevention tool for crawl space mold in Spangler, PA properties.
Systems
🏔Encapsulation vs. Vented Conditioning Assessment
Encapsulation isn't always the right answer. We assess your Spangler, PA crawl space's specific moisture load, drainage, and soil conditions and recommend encapsulation or enhanced vented conditioning based on what will actually work — not on which option has a higher margin.
