Protocol First 🡢 Contained 🡢 Verified.
CRE performs commercial mold remediation after water events, leaks and chronic moisture in offices, retail, healthcare, hospitality and institutional buildings across New York City, Long Island, Westchester and the Tri-State area. We work to the written protocol of an independent, licensed mold assessor — as New York State law requires — and we support the post-remediation verification that lets you reoccupy with confidence. When the space has to be rebuilt afterward, CRE does that too.
Active leak or flooding? Stop the water first, then call us — 24/7.

Post-remediation verification confirms the result before rebuild and reoccupancy.
Commercial mold remediation is the containment, removal and cleaning of mold-contaminated materials, plus correction of the moisture that caused it, so a building can be reoccupied safely. In New York State, mold work over 10 contiguous square feet must be done by a licensed remediator under a written protocol from a separate, independent licensed assessor, who also verifies the result afterward.
Mold needs moisture. That is why remediation always starts with the water: a ceiling that is dried and patched while the leak continues will grow mold again. Fogging, spraying or painting over mold is not remediation.
Pipe bursts, roof leaks, sprinkler discharge and flooding wet porous materials. Mold can begin to grow within 24 to 48 hours (EPA), so fast drying and early assessment matter.
HVAC condensation, below-grade leaks and poor ventilation produce recurring mold in basements, mechanical rooms, kitchens and restrooms. Remediation has to be paired with fixing the cause.
Stains, fuzzy growth or musty odor behind finishes, above ceilings or in wall cavities should be assessed by an independent licensed professional rather than cleaned by building staff.
Lenders, tenants and insurers often require documented remediation and clearance. We coordinate with the water-damage contractor so drying, remediation and rebuild stay in sequence.
| Role | Who | What they do |
|---|---|---|
| Mold assessor | Independent, NYS-licensed | Inspects, writes the remediation protocol and performs the post-remediation assessment. Cannot also remediate the same project |
| Mold remediator | CRE (NYS-licensed contractor) | Carries out the protocol: containment, removal, cleaning and documentation. Cannot also assess the same project |
| Water-damage / restoration contractor | Your restoration vendor | Stops the water and dries the structure, then coordinates with the remediator |
| Plumber, roofer, HVAC contractor | Trade contractors | Repair the moisture source |
| Owner / property manager / GC | Client | Retains the assessor and remediator separately and keeps the documents |
The NYC Department of Health’s guidelines on mold in commercial buildings — advisory, and written before Article 32 — group work by size. They are a useful reference for how controls scale, but the state law is what sets the licensing requirements.
| Affected area | Typical controls |
|---|---|
| Under 10 sq ft | Localized removal, HEPA vacuuming and damp wiping with basic protective equipment; Article 32 licensing generally does not apply |
| 10–100 sq ft | Defined work area with plastic barriers and HEPA filtration, upgraded respiratory protection; Article 32 applies |
| Over 100 sq ft | Full containment with negative air and a decontamination chamber, full protective equipment; Article 32 applies |
The moisture source has to be corrected and the structure dried, by your plumber, roofer or restoration contractor. We coordinate with them so remediation does not start on a wet building.
An independent licensed mold assessor inspects, identifies the affected areas and writes the remediation protocol. We can introduce qualified assessors, but we cannot assess a job we remediate.
Plastic containment, negative air pressure, HEPA air scrubbers and a decontamination area isolate the work from the rest of the building, scaled to the size and location of the contamination.
Contaminated porous materials such as drywall, ceiling tile and insulation are removed and bagged; surfaces are HEPA vacuumed and damp-wiped per the protocol. We do not fog or paint over mold.
Moisture readings confirm the structure is dry before closure and rebuild. Persistent moisture is reported to you and your trades in writing.
The independent assessor inspects and clears the area. We deliver the documentation — protocol, photos, waste records and clearance — for your files, lender or carrier.
Moisture source fixed; area dried
Independent clearance issued
Drywall, ceilings, flooring and finishes rebuilt
— the rebuild
Mold remediation removes wet drywall, insulation and finishes. Nothing goes back until the independent assessor clears the area and the moisture source is fixed. Then the space needs new drywall, insulation, ceilings, flooring and finishes.
CRE performs the rebuild as well as the remediation, and sequences it in one schedule: dry, clear, then rebuild. The assessor stays independent of the remediator, as Article 32 requires. If another contractor rebuilds, we hand over the clearance documentation.
We work in occupied and vacant buildings, and alongside restoration contractors after a loss. Work areas are isolated from occupied space and scheduled around your operations.
We follow the protocol, document the work and coordinate the drying, trade and rebuild handoffs — and we answer for the remediation. You do not have to referee between vendors.
New York's mold law is specific, and so is our process. Independent assessment, a written protocol and independent clearance protect you, your tenants and your claim file.
Water events involve drying, demolition, remediation and rebuild. We sequence our work with theirs so the building does not sit wet or empty longer than necessary.

New drywall, ceilings and finishes once the assessor clears the area.
Tear-out of water-damaged finishes before or after remediation, under one contractor.
Water-damaged ceilings and pipe insulation in older buildings may contain asbestos. We screen first.
Regulated materials found in water-damaged areas handled and manifested correctly.
Sequencing and documentation help for large losses, multi-trade projects and lender or carrier requirements.
Mold problems follow water. In Manhattan, high-rise leaks and sprinkler discharges move through floors and risers; in Brooklyn, Queens and the Bronx, older buildings and below-grade spaces hold moisture; on Staten Island, Long Island and in Westchester, flooding and storm events drive many projects.
The state mold law applies across New York; if your site is in New Jersey, Connecticut or Pennsylvania, local rules apply and we confirm them first.
Beyond the five boroughs
For projects over 10 contiguous square feet in New York, yes — an independent licensed mold assessor must inspect and write the remediation protocol. Even for smaller areas, an assessment helps find the moisture source and the full extent of the contamination.
No, and the law is the reason. New York’s Labor Law Article 32 bars the same company from assessing and remediating the same project. We work with independent licensed assessors, and we follow their protocol.
Cost depends on the affected area, the materials involved, the containment and air filtration needed, access and work hours, and whether the building is occupied. Drywall in one office is a different job from contamination in a ceiling plenum or an HVAC chase. We price from the assessor’s protocol and a site visit.
A small, well-defined area can take days; larger or hidden contamination takes longer. The schedule also depends on drying and clearance. We give you a written schedule once we have the protocol and tell you early if the building’s drying or access affects it.
Often, yes, if the work area is properly isolated and the building’s air handling is controlled, but it depends on the size, location and protocol. For healthcare and other sensitive spaces we apply stricter controls. We confirm with you and the assessor before mobilizing.
Coverage varies by policy. Many policies cover mold that results from a covered water loss, often with limits or sub-limits, while mold from long-term moisture may be excluded. Check with your carrier and broker, and ask us for the documentation they typically require.
Yes. After the independent assessor clears the area, CRE can rebuild the drywall, insulation, ceilings, flooring and finishes that were removed, on the same schedule. If another contractor rebuilds, we hand over the clearance documentation.
