Frequently Asked Questions

How does FIRST ONSITE handle hardwood floor water damage and river flood damage in New York?

New York properties near rivers and coastal areas often face flood damage from storms or high tides, which can warp hardwood floors. We start with a full inspection to assess water penetration and structural risks. Using industrial-grade extraction and drying equipment, we remove standing water and moisture from under the flooring. If floors are salvageable, we stabilize and refinish them; if not, we coordinate replacement and reconstruction—all while minimizing downtime. Our team is familiar with local building codes and the specific challenges of historic buildings near neighborhoods like Tribeca or the Upper East Side.

What does biohazard cleanup involve in a residential setting?

Biohazard cleanup addresses situations like crime scenes, unattended deaths, or hoarding environments. We follow strict OSHA and EPA protocols, using personal protective equipment and hospital-grade disinfectants. Our trained technicians safely remove biological materials, decontaminate all surfaces, and neutralize odors. We also handle proper disposal of hazardous waste. This service is available 24/7 for New York homeowners, ensuring the property is restored to a safe, livable condition.

Can you explain the mold remediation process for a New York apartment or commercial space?

Yes. First, we conduct a moisture assessment and air quality testing to locate hidden mold, often behind walls or under carpets. We contain the area with negative air pressure to prevent spores from spreading. Using HEPA vacuums and antimicrobial treatments, we remove mold growth and clean ductwork if needed. After remediation, we seal and restore the surfaces—whether drywall, wood, or tile. We also address the moisture source (e.g., a leaking pipe or drain backup) to prevent recurrence. For New York properties, this process is critical in older buildings where humidity and water intrusion are common.
