Found mold in your NYC apartment or building? Our IICRC-certified remediation specialists contain, remove, and verify — safely and completely. We handle insurance claims and comply with NYC Local Law 55 mold regulations.
From initial inspection through post-remediation clearance testing, we handle every phase of mold removal.
Air sampling, surface testing, and moisture mapping to identify all mold sources — including hidden mold behind walls and under floors that visual inspection can miss.
Before removal begins, we establish containment barriers with negative air pressure to prevent spores from spreading through your apartment. Full PPE for all workers.
Physical removal of affected materials, HEPA vacuuming, antimicrobial treatment, and encapsulation where appropriate. We remove mold at the source — not just surface cleaning.
After remediation, we conduct clearance air testing to verify mold levels have returned to acceptable ranges. You receive a formal clearance report for insurance and legal purposes.
New York City has one of the highest rates of residential mold in the country. The causes are structural and climatic: aging building stock with poor ventilation, high ambient humidity, aging plumbing that leaks chronically, and the simple reality of millions of people living in dense, often poorly-maintained apartments.
NYC's housing stock includes buildings with inadequate vapor barriers, outdated insulation, and plumbing systems that have been patched and re-patched for decades. A pipe that leaked six months ago and was "fixed" by painting over the water stain may have left a thriving mold colony inside the wall cavity. The mold continues growing, releasing spores into the air your family breathes every day.
New York City has some of the most comprehensive mold legislation in the country, established under Local Law 55 of 2018. Key provisions include:
Mold exposure affects approximately 25% of the population more severely than others, particularly those with mold allergies, asthma, compromised immune systems, or genetic predispositions to mycotoxin sensitivity. However, any significant mold exposure in a home environment poses health risks:
Our remediation process follows IICRC S520 standard for mold remediation and complies with NYC Local Law 55 requirements:
Small localized areas typically cost $500–$3,000. Larger projects involving multiple rooms, wall cavities, or HVAC systems run $3,000–$15,000+. Cost depends on affected area size, mold type, and reconstruction needed. We provide detailed upfront estimates after inspection.
Under NYC Local Law 55, landlords must remediate mold when areas exceed 10 square feet. They must hire licensed contractors and cannot retaliate against tenants who report mold. Document conditions and notify your landlord in writing. House Help Services provides documentation for housing court or HPD complaints.
Black mold (Stachybotrys) produces mycotoxins that cause respiratory problems and other health effects. But any visible mold should be remediated — all mold indicates moisture problems and poses health risks, especially for those with allergies, asthma, or compromised immune systems.
DIY removal is only appropriate for very small areas under 10 square feet on non-porous surfaces. Larger areas, inside walls, HVAC systems, or any visible black mold requires professional remediation. Improper removal spreads spores throughout your unit.
Signs include: persistent musty odors, unexplained allergy symptoms that improve when you leave home, moisture staining or bubbling paint, history of water damage, and chronically high indoor humidity. Our inspectors use moisture meters and air sampling to detect hidden mold without unnecessary demolition.
