Why Choose Us

4 Reasons Jericho Clients Call Us First

IICRC-certified specialists with real field experience in Jericho, NY.

🔨
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 Jericho, NY 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 Jericho, NY property.
✅
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 Jericho, NY Properties

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

🔍
Crawl Space Mold Assessment & Moisture Mapping
Before any remediation work starts in your Jericho 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 Jericho, NY 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 Jericho, NY 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 Jericho crawl space climate and construction.
⚡
Ventilation Correction & Dehumidifier Installation
Additional vents, power ventilation, or a dedicated crawl space dehumidifier — we identify the right ventilation solution for your specific Jericho, NY crawl space based on its geometry, construction, and moisture load.
📄
Post-Remediation Clearance & Moisture Verification
After Crawl Space Mold Removal in your Jericho, NY 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 Jericho, NY Clients Say About Our Crawl Space Mold Removal

★★★★★
Musty smell throughout our Jericho 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.

The crawl space mold under our Jericho, NY rental property was causing complaints from tenants about musty odor in the first-floor bedrooms. Cheap Mold Removal did the remediation, replaced the vapor barrier, and added ventilation. Independent post-clearance confirmed clean air quality. No tenant complaints since.

★★★★★
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 Jericho, NY Properties

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