From joist treatment to vapor barrier replacement and encapsulation — the full scope of crawl space mold remediation in Lewisville, WA.
🔍
Crawl Space Mold Assessment & Moisture Mapping
Our Lewisville, WA crawl space inspectors enter the space with calibrated moisture meters and assess joist moisture content readings at regular intervals, map the extent of visible fungal growth, evaluate vapor barrier condition, and measure ventilation cross-flow. Findings documented with photos and written scope before any work begins.
🔨
Joist & Subfloor Sheathing Mold Removal
HEPA vacuum and wire-brush removal of fungal growth from accessible joist and sheathing surfaces. Where structural integrity is compromised by fungal digestion, affected sections are removed and sistered with treated lumber.
💧
Vapor Barrier Repair & Replacement
Vapor barrier inspection, repair, or full replacement with properly-lapped, footing-secured reinforced poly. This is often the single most impactful long-term fix for chronic crawl space mold in Lewisville, WA homes.
🏔
Encapsulation for Severe Moisture Environments
For Lewisville, WA crawl spaces with chronic high humidity, standing water, or soil moisture problems that ventilation alone can't address, full encapsulation with a sealed vapor barrier, insulated walls, and conditioned air supply is the definitive long-term solution. We assess whether encapsulation or vented conditioning is more appropriate for your Lewisville crawl space climate and construction.
⚡
Ventilation Correction & Dehumidifier Installation
Where crawl space cross-ventilation is inadequate, our Lewisville, WA team identifies additional vent locations, sizes existing vents against square footage, and where appropriate, installs a dedicated crawl space dehumidifier with external drain or condensate pump. Mechanical dehumidification is sometimes the most practical solution for chronically humid Lewisville crawl spaces.
📄
Post-Remediation Clearance & Moisture Verification
After Crawl Space Mold Removal in your Lewisville, WA crawl space, we re-measure joist moisture content to verify they're below the critical threshold (typically below 19% for wood) and arrange independent post-remediation air sampling. Written clearance documentation confirms the job achieved its objective.
