Why Choose Us

4 Reasons Martinsville Clients Call Us First

Specialized expertise, fast response, and documented results — every time.

🔨
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 Martinsville, IL 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.

Complete Crawl Space Mold Removal Services for Martinsville, IL Properties

From joist treatment to vapor barrier replacement and encapsulation — the full scope of crawl space mold remediation in Martinsville, IL.

🔍
Crawl Space Mold Assessment & Moisture Mapping
Our Martinsville, IL 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
Ground cover vapor barrier is the first line of defense against crawl space moisture. Torn, absent, or undersized vapor barriers allow ground evaporation to raise relative humidity in the space to mold-favorable levels. We repair or replace with 6-mil minimum reinforced poly — properly overlapped and secured to footings and piers.
🏔
Encapsulation for Severe Moisture Environments
Full crawl space encapsulation — sealed ground cover, insulated perimeter walls, and conditioned air — is warranted in high-moisture-load situations where passive ventilation is insufficient. We assess your specific Martinsville, IL conditions before recommending encapsulation vs. enhanced ventilation.
Ventilation Correction & Dehumidifier Installation
Where crawl space cross-ventilation is inadequate, our Martinsville, IL 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 Martinsville crawl spaces.
📄
Post-Remediation Clearance & Moisture Verification
After Crawl Space Mold Removal in your Martinsville, IL 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.

Customer Reviews

What Martinsville, IL Clients Say About Our Crawl Space Mold Removal

★★★★★
Musty smell throughout our Martinsville 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.

★★★★★
Post-flood crawl space remediation after groundwater intrusion during heavy rains. Cheap Mold Removal pumped standing water, allowed drying, then returned for full joist and sheathing mold remediation. The vapor barrier replacement and additional sump recommendation were part of the scope. Insurance adjuster had everything they needed from their documentation.

FAQ

Crawl Space Mold Questions for Martinsville, IL Properties

Crawl space joist mold in Martinsville, IL 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 Martinsville, IL 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 Martinsville homeowners often report musty odors in bedrooms and living rooms, not just when they open the crawl space access hatch.
Most residential Martinsville, IL 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.
Not always — it depends on the moisture load and construction type of your specific Martinsville crawl space. Vented crawl spaces in areas where outdoor humidity is manageable and ground moisture is controllable with a proper vapor barrier often perform well after remediation plus vapor barrier upgrade. Full encapsulation (sealed vapor barrier, insulated perimeter walls, conditioned air) is warranted in high-moisture-load situations — particularly in humid climates, areas with high water tables, or crawl spaces where passive ventilation has chronically failed. We assess and recommend based on your specific conditions, not a default recommendation for the most expensive option.
