Black mold (Stachybotrys chartarum) is the most frequently cited mold concern in New York City properties. It thrives in persistently damp areas such as basements, bathroom walls, and spaces with poor ventilation. We identify and safely remove black mold at the source, treat the underlying surface, and address the moisture condition that allowed it to grow in the first place.

Before any remediation starts, a proper mold inspection identifies every affected area, including hidden mold behind walls and under flooring. We conduct visual assessments, moisture readings, and air quality sampling to produce a detailed mold inspection report. This report tells you exactly what is present, where it is, and what level of remediation is required before a contractor touches anything.

Basements and crawl spaces are the most mold-prone areas in New York City buildings due to humidity, poor airflow, and proximity to groundwater. We remove mold from concrete blocks, floor joists, subfloor framing, and insulation, install vapor barriers where appropriate, and recommend ventilation improvements to prevent regrowth after remediation is complete.

Mold can begin developing within 24 to 48 hours of water damage. Whether the source was a burst pipe, a roof leak, a storm flood, or a sewage backup, we combine water extraction, structural drying, and mold remediation into a single coordinated process. Acting fast after water damage is the single most effective way to prevent a minor mold problem from becoming a major remediation project.

Mold in a New York property is not just an aesthetic problem. It is a health risk for occupants, a potential lease and legal liability for landlords, and something that spreads fast in the city's humid summers and damp building stock. Here is what New York property owners and managers get when they call us.
Round-the-clock emergency mold removal for NYC properties: flood response, water damage mold, and visible mold growth across all five boroughs.
Call Us Now — 24/7Mold removal price in New York City varies depending on the size of the affected area, the type of mold present, and the surfaces involved. A small bathroom mold issue is a very different job from a full basement remediation following a flood. We always begin with a free mold inspection so the scope of work reflects the actual problem, not a worst-case estimate. New York's older building stock, humid summers, and frequent water damage from aging pipes all contribute to mold being one of the most common issues property owners deal with in this city.
New York City Local Law 55 of 2018 requires building owners to address indoor mold hazards in residential buildings. Mold affecting an area of 10 square feet or more must be remediated by a licensed mold remediation contractor, and an assessment must be performed by a licensed mold assessor. Landlords who ignore mold complaints face HPD violations and potential legal liability. Tenants have the right to request a mold inspection, and landlords are required to respond and remediate. We work with both landlords and tenants to document, remediate, and obtain post-remediation clearance in full compliance with NYC mold law.
We are a locally based New York mold removal company, not a distant national chain. From the Upper West Side and Harlem to Park Slope and the South Bronx, our certified mold remediation contractors reach you fast for inspections, emergency mold removal, and full remediation projects.

"We discovered extensive black mold in the basement of our Harlem brownstone following a slow pipe leak. The team came out the same day, did a thorough inspection, and gave us a detailed written estimate. The remediation was done in two days and they provided the clearance report we needed to satisfy our insurance company. Excellent from start to finish."
"After a bathroom pipe burst in our Astoria co-op, we had mold growing on two walls within a week. I called for an emergency inspection and they arrived within hours. The containment was set up that afternoon and the mold was fully remediated by the following day. They also identified a second hidden patch behind the vanity that we would never have found on our own. Really thorough work."
