🔨
Crawl Space Entry & Joist Assessment
Calibrated moisture meters on joists and sheathing, visual assessment of vapor barrier condition, and fungal growth mapping — before any remediation begins in your New Brunswick, NJ crawl space.
💧
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 New Brunswick, NJ crawl space remediation scope when warranted.
💨
Ventilation Assessment & Cross-Flow Improvement
Inadequate cross-ventilation allows humidity to build in the crawl space. We assess vent count, vent placement, and cross-flow adequacy — identifying ventilation corrections that work alongside the mold remediation to prevent recurrence in your New Brunswick, NJ property.
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 New Brunswick crawl space remediations.
Service Solutions

What Our New Brunswick Below-Grade Team Does

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

🔍
Crawl Space Mold Assessment & Moisture Mapping
Our New Brunswick, NJ 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
Surface mold on joists (typically Penicillium, Aspergillus, or Cladosporium in most New Brunswick, NJ 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
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
For New Brunswick, NJ 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 New Brunswick crawl space climate and construction.
Ventilation Correction & Dehumidifier Installation
Where crawl space cross-ventilation is inadequate, our New Brunswick, NJ 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 New Brunswick crawl spaces.
📄
Post-Remediation Clearance & Moisture Verification
Post-remediation moisture re-check plus independent post-removal air sampling. Joist moisture content below threshold, post-clearance air sample confirming reduced spore counts — both documented in your written clearance report.

Customer Reviews

What New Brunswick, NJ Clients Say About Our Crawl Space Mold Removal

★★★★★
Musty smell throughout our New Brunswick 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 New Brunswick, NJ Properties

Crawl space joist mold in New Brunswick, NJ 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.
Bleach applied to crawl space joists has several significant limitations: it can't penetrate below the wood surface where the fungal hyphae are embedded, it doesn't address the moisture condition driving the growth, and it kills only the surface cells — leaving the structural mold network intact. The mold typically returns within weeks to months because the moisture source hasn't been corrected. Professional Crawl Space Mold Removal using HEPA vacuuming, EPA-registered penetrating fungicides, and borate treatment — combined with vapor barrier repair and ventilation correction — produces results that last because it addresses the root cause.
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 New Brunswick homeowners often report musty odors in bedrooms and living rooms, not just when they open the crawl space access hatch.
Most residential New Brunswick, NJ 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 New Brunswick, NJ 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 New Brunswick crawl space based on what we find during assessment.
