Complete Crawl Space Mold Removal Services for Old Westbury, NY Crawl Spaces

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
Loose and surface mold growth on joists and sheathing is removed using industrial HEPA vacuuming and wire brushing — capturing spore material rather than disturbing it into the airspace. Contained removal prevents spore migration upward through the subfloor assembly into living areas.
Treatment
🌳Penetrating Borate Application
EPA-registered penetrating borate solution applied to all accessible joist and sheathing surfaces after HEPA removal. Borate diffuses into wood fiber over time, providing ongoing inhibition of fungal colonization — including species that may not be visually apparent yet. Borate remains active in treated wood for years.
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
Ground cover vapor barrier in your Old Westbury, NY crawl space — whether torn, undersized, incorrectly lapped, or absent — is repaired or replaced with properly installed reinforced poly, overlapped at seams, and secured to footings and piers. This is often the highest-impact single correction for preventing crawl space mold recurrence.
Systems
🏔Encapsulation vs. Vented Conditioning Assessment
Encapsulation isn't always the right answer. We assess your Old Westbury, NY 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.

Client Reviews

Crawl Space Mold Reviews — Old Westbury, NY

★★★★★
Two years of musty odor in our Old Westbury 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.

★★★★★
Investment property in Old Westbury, NY with crawl space mold discovered during a renovation. Cheap Mold Removal assessed the full extent using moisture meters — much larger than what was visible. Full HEPA removal, borate treatment on all accessible framing, complete vapor barrier replacement, and two additional soffit vents added. Written clearance passed first round. Their documentation was exactly what our insurance adjuster needed.

Property manager, Old Westbury, NY
★★★★★
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 Old Westbury 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 Old Westbury 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 Old Westbury, NY 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.
Stack effect pulls crawl space air upward into the living space. Elevated mold spore counts below grade mean elevated counts in your Old Westbury first-floor living areas. Musty odors in upper-floor rooms that you trace back to the crawl space are a reliable signal that the below-grade air quality is affecting the entire house.
Encapsulation isn't always the right answer for a Old Westbury 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.
