Mold Removal on Long Island, NY

NYS-licensed mold inspection and remediation for Nassau and Suffolk homes — basements, crawlspaces, and Levitt-era attics, with same-day inspections from Great Neck to Patchogue.

Call (332) 355-0263 — 24/7 Long Island Response

Quick answer: We provide NYS Article 32 licensed mold assessment and remediation across Nassau and Suffolk County, with same-day inspections and 24/7 emergency dispatch for active leaks and flooding. Most Long Island jobs finish in 1–3 days and always end with independent post-remediation clearance testing performed by an assessor separate from the remediation crew.

Long Island Building Stock & Mold Risk

Long Island's housing stock is dominated by post-war Levitt-era ranches, split-levels, and Capes built quickly in the 1950s, most with full basements or crawlspaces and attics that were never properly vented. On the South Shore, the water table sits just a few feet below sandy soil, and thousands of homes still carry residual moisture damage from Hurricane Sandy. In Suffolk, aging cesspool and septic systems add another chronic source of ground moisture beneath slabs and crawlspaces.

Most Common Mold Problems in Long Island

Basement and foundation seepage, often paired with failed or undersized sump pumps
Crawlspace mold in South Shore homes with raised foundations and bare-earth floors
Attic mold from soffit-to-ridge ventilation failure in Levitt-era Capes and ranches
Post-Hurricane-Sandy residual moisture on the South Shore (Long Beach, Freeport, Massapequa, Bay Shore)
HVAC and ductwork mold in central-air homes running long summer cooling cycles
Finished-basement mold from unvented laundry rooms and bathroom exhaust fans

Why Mold Is So Common in Long Island

Sandy soil and a shallow water table on the South Shore keep foundations and crawlspaces damp year-round
Nearly every Long Island home has a basement or crawlspace — the two spaces where mold starts first
Sandy-era flood damage left moisture inside wall and floor cavities that still drives recurring growth
Humid coastal summers combined with tightly retrofitted 1950s building envelopes trap that moisture indoors

Long Island Mold Removal FAQ

Do you serve both Nassau and Suffolk County?

Yes — we cover all of Nassau and western and central Suffolk, from Great Neck, Garden City, and Long Beach out through Huntington, Bay Shore, Smithtown, and Patchogue. Same-day inspections are usually available across Nassau, with 24/7 emergency dispatch for active leaks and flooding anywhere on the Island.

Do you handle post-Hurricane Sandy mold on the South Shore?

We do. South Shore homes in Long Beach, Freeport, Massapequa, and Bay Shore often still hold moisture inside wall cavities, subfloors, and crawlspaces from Sandy-era flooding, even after the visible repairs were done years ago. We use moisture mapping to find the wet cavities before opening walls, and we document everything for insurance and FEMA claims.

Is a NYS mold license required on Long Island?

Yes. New York State Article 32 applies statewide, including Nassau and Suffolk County, and it requires that the mold assessor be independent of the company performing the remediation. We are licensed for both, and we always bring in a separate independent assessor for post-remediation clearance testing so your job is compliant and your clearance report holds up.
