What Our Beaverton Below-Grade Crew Does

Every crawl space is different. Every scope is written after we've been in yours.

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
Borate application after HEPA removal on all accessible surfaces. Penetrating formulation diffuses into wood fiber, not just surface coat. Active for years in treated wood.
Structure
🔨Sistering Structurally Compromised Joists
Individual joist assessment for structural integrity. MC readings plus physical assessment of deterioration. Sister framing specified where structural capacity is compromised — documented in 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 Beaverton, OR properties.
Systems
🏔Encapsulation vs. Vented Conditioning Assessment
Encapsulation isn't always the right answer. We assess your Beaverton, OR 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.

What Beaverton Homeowners Say About Cheap Mold Removal

★★★★★
Two years of musty odor in our Beaverton home. Two contractors told us to 'add a dehumidifier.' Cheap Mold Removal was the first crew to actually bring a moisture meter into the crawl space — joist readings at 26–28%, active Penicillium growth on roughly 400 square feet of sheathing, and a vapor barrier that was 40% missing. They scoped the full correction, completed it in two days, and the smell was gone before the end of the week. Post-clearance air sampling confirmed clean.

★★★★★
Rental property management — crawl space mold complaint from first-floor tenant (musty smell in the floors above). Cheap Mold Removal confirmed significant joist growth, completed the full remediation, and provided written clearance documentation. Tenant complaint resolved and property protected from further structural moisture damage.
Susan K.
Property manager, Beaverton, OR
★★★★★
Cheap Mold Removal did our crawl space remediation after a plumbing leak from above had been undetected for what looked like six months. Joist MC readings peaked at 31% in one zone — both mold and early decay fungi present. Their scope included sistering three deteriorated joists, HEPA removal, borate treatment, and vapor barrier replacement. Written clearance confirmed complete.

Frequently Asked Questions

What Beaverton Homeowners Ask About Below-Grade Mold

Below 19% MC: generally below active mold risk threshold. 19–28%: active mold risk zone. Above 28%: both mold and potential decay fungi territory. We measure multiple points across your Beaverton crawl space — not one spot near the access hatch.
Bleach on crawl space joists has three significant limitations: it can't penetrate into wood fiber where fungal hyphae are embedded (so it kills surface cells while leaving the root structure intact), it doesn't address the moisture condition driving the growth (so the colony reestablishes from the surviving hyphae within weeks to months), and it doesn't include the vapor barrier and ventilation corrections that are the actual long-term solution. Professional remediation uses HEPA extraction to capture and remove surface spore material, penetrating borate to inhibit regrowth in the wood fiber, and moisture source correction to change the conditions.
Most Beaverton, OR residential crawl space remediations complete in one to two days. Larger spaces or those with significant vapor barrier replacement and ventilation correction work may run two to three days. We give a specific timeline with the written scope.
Yes — stack effect drives crawl space air upward through floor assembly gaps, utility penetrations, and subfloor-to-wall junctions into the living space above. Estimated crawl space air contribution to first-floor indoor air in a vented crawl space home is significant — which is why musty odors originating below grade are often noticed in bedrooms and living areas, not just at the crawl space access hatch. Elevated spore counts in a Beaverton, OR crawl space translate directly to elevated counts in the living space above.
Encapsulation isn't always the right answer for a Beaverton crawl space. We assess drainage, water table, soil moisture, and climate conditions before recommending encapsulation vs. enhanced vented conditioning. The more expensive option isn't always the better option for your specific situation.
