Why LI Mold Co.
Mold doesn’t appear because your house is dirty. It appears because something is wet that shouldn’t be. Find the moisture, fix the moisture, remove the mold — in that order — or it comes back in six months. That’s the Long Island Mold Co. difference.
Separate assessment arm and remediation arm. Your inspector never benefits from finding more mold to remove. Required by NY law since 2015 — many competitors still ignore it.
Air and surface samples go to a third-party AIHA-accredited lab. You get the lab report directly, with species names, spore counts, and outdoor-indoor comparison.
Negative-air containment with commercial AFDs on every job over 30 sqft. We don't just clean — we stop cross-contamination cold.
We don't just kill the mold. We fix the blocked bath fan, the roof vent, the vapor barrier — whatever caused it. A clean house that stays clean.
400+ Stachybotrys jobs since Sandy. We know how to contain it, treat it, and verify clearance on black mold that sends the guys in Tyvek running.
Every report written the way adjusters need them. Photos, moisture readings, S520 scope references, cause-of-loss narrative. Angela runs this step every time.

Remediation
Full IICRC S520 remediation — containment, HEPA filtration, removal, and clearance. Our core service.
EmergencyEmergency Stachybotrys removal with negative-air containment, respirator-grade crew, and PRV clearance testing.
The #1 mold problem in Long Island homes — sheathing mold from blocked bath fans and under-vented roofs. We treat the wood and fix the ventilation.
From crawl-space dampness to finished-basement flood damage. South Shore specialty — Sandy legacy and nor'easter water events.
Vapor barriers, joist treatment, dehumidification — the three-step fix for chronic crawl-space mold in older LI homes.
Hidden behind tile, under vanities, and inside wall cavities — most bathroom mold comes from pinhole leaks that have been wet for years.

Found black mold behind our bathroom vanity after a pipe leak. Carlos came out next morning, air-tested, showed us moisture readings on the meter. Pete's crew contained the room and had it remediated in two days. Clearance test came back clean. Insurance paid most of it because Angela knew exactly how to write the report.

Attic mold, thousands of spots on the sheathing. Three other companies wanted $14k. LI Mold Co. came in with a real plan — fix the bath fan venting first, then treat the wood, then repair the ridge vent. Half the price. A year later the attic is still clean.

Post-Sandy basement that flooded again in a nor'easter. Frank walked me through the S520 scope himself. No upsell, no scare talk. The containment and HEPA setup was surgical. Highly recommend.
