Why Choose Us

4 Reasons Alexandria Clients Call Us First

IICRC-certified specialists with real field experience in Alexandria, MN.

🔨
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 Alexandria, MN 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
After physical removal of severely infected material where needed, remaining joists and sheathing are treated with EPA-registered fungicide — including penetrating borate solutions that diffuse into wood fiber to inhibit future fungal growth. Borate treatment is standard on all accessible wood surfaces in Alexandria crawl space remediations.

What Our Alexandria Below-Grade Team Does

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

🔍
Crawl Space Mold Assessment & Moisture Mapping
Before any remediation work starts in your Alexandria crawl space, we map moisture content zone by zone, photograph all visible mold growth, and assess the vapor barrier and ventilation — giving you a clear picture of what's there and what's needed.
🔨
Joist & Subfloor Sheathing Mold Removal
Surface mold on joists (typically Penicillium, Aspergillus, or Cladosporium in most Alexandria, MN crawl spaces) is removed using HEPA vacuuming and wire-brushing on accessible surfaces. Severely deteriorated sections of joist or sheathing may require replacement where structural integrity is compromised by fungal digestion.
💧
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 Alexandria, MN homes.
🏔
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 Alexandria, MN conditions before recommending encapsulation vs. enhanced ventilation.
⚡
Ventilation Correction & Dehumidifier Installation
Additional vents, power ventilation, or a dedicated crawl space dehumidifier — we identify the right ventilation solution for your specific Alexandria, MN crawl space based on its geometry, construction, and moisture load.
📄
Post-Remediation Clearance & Moisture Verification
After Crawl Space Mold Removal in your Alexandria, MN 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

Real Crawl Space Reviews From Alexandria Property Owners

★★★★★
Musty smell throughout our Alexandria 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 Alexandria, MN Properties

Crawl space joist mold in Alexandria, MN 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 Alexandria, MN 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 Alexandria homeowners often report musty odors in bedrooms and living rooms, not just when they open the crawl space access hatch.
Most residential Alexandria, MN 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 Alexandria 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.
