Why Choose Us

4 Reasons Beaverton Clients Call Us First

IICRC-certified specialists with real field experience in Beaverton, OR.

🔨
Crawl Space Entry & Joist Assessment
We assess every linear foot of accessible joist and sheathing. Moisture content readings, vapor barrier condition, ventilation cross-flow measurement.
💧
Vapor Barrier Repair & Replacement
Failed, torn, or inadequate vapor barriers allow ground moisture to evaporate directly into the crawl space — creating the humidity that feeds mold on joists above. Vapor barrier repair or full replacement is part of our Beaverton, OR crawl space remediation scope when warranted.
💨
Ventilation Assessment & Cross-Flow Improvement
Vent count, size, and placement affect crawl space humidity. We identify ventilation deficiencies and recommend corrections alongside the mold removal.
✅
Fungicidal Treatment & Borate Application
EPA fungicide plus penetrating borate application on all accessible joist and sheathing surfaces. Borate diffuses into wood fiber over time, providing ongoing protection against fungal re-establishment.

Customer Reviews

Real Crawl Space Reviews From Beaverton Property Owners

★★★★★
Musty smell throughout our Beaverton home for two years — every contractor we called said it was 'just humidity.' Cheap Mold Removal was the first company to actually go into the crawl space with moisture meters. Found joist MC readings at 24% and significant Penicillium growth across 60% of the accessible joists. HEPA removal, borate treatment, new vapor barrier, two additional vents added. Smell was gone within a week of completion. Clearance test confirmed clean.

We had a home inspector flag mold in the crawl space during a sale. Cheap Mold Removal remediated it within the contract contingency period — full scope including vapor barrier replacement, joist treatment, and borate application. They provided the written clearance report and before/after photos within the timeline we needed. Sale closed on time.

★★★★★
Had a home energy auditor mention possible mold in the crawl space. Cheap Mold Removal came out, confirmed active mold growth on the rim joists and lower sheathing, and provided a detailed written scope. Their crew completed the full remediation in one day — HEPA removal, fungicide, borate treatment, and vapor barrier work. They handed us a clearance report and joist moisture readings all below 16%. Exactly what we needed.

FAQ

What Beaverton Homeowners Ask Us

Crawl space joist mold in Beaverton, OR almost always traces back to moisture: failed vapor barrier, inadequate ventilation, plumbing leaks, or groundwater intrusion. High relative humidity in the space — typically above 70% RH — creates the conditions for Penicillium, Aspergillus, and Cladosporium to colonize wood surfaces. Identifying and correcting the moisture source is as important as treating the mold.
DIY bleach treatment on crawl space joists is one of the most common 'temporary fix' scenarios we encounter in Beaverton, OR homes. It can knock back visible surface growth briefly, but without penetrating treatment and moisture source correction, regrowth is almost certain. Professional treatment plus vapor barrier and ventilation correction is the only approach that produces lasting results.
Stack effect draws crawl space air upward into living areas — it's estimated that a significant percentage of first-floor air comes from below. Elevated crawl space spore counts translate directly to elevated living space counts. This is why Beaverton homeowners often report musty odors in bedrooms and living rooms, not just when they open the crawl space access hatch.
Most residential Beaverton, OR crawl space remediations complete in one to two days. Larger spaces or those requiring significant vapor barrier replacement or ventilation work may take longer. We give you a specific timeline estimate with the written scope after the on-site assessment.
Encapsulation is the right solution for some Beaverton, OR crawl spaces — particularly those with high moisture loads, poor drainage, or where enhanced ventilation alone hasn't controlled humidity. For others, a proper vapor barrier plus ventilation correction achieves the same outcome at lower cost. We'll tell you which is appropriate for your specific Beaverton crawl space based on what we find during assessment.
