Step-by-Step Lead Removal Process in NYC
The lead paint removal process in NYC follows a specific sequence required by EPA regulations and NYC law. According to DeLead NYC, understanding each step helps property owners prepare, budget, and ensure their contractor is doing the work correctly.
An EPA-certified inspector uses an XRF device to test every painted surface in the unit. The device detects lead concentration instantly — no destructive sampling needed. Cost: $150-$300 per unit.
Based on XRF results, the contractor identifies which components need abatement and provides a detailed estimate. Only surfaces with lead above the action level require work.
Before any work begins, the crew seals the work area: 6-mil polyethylene sheeting on floors and doorways, negative air pressure with HEPA filtration, warning signs posted, and building management notified.
Using wet methods (misting surfaces to prevent dust), the crew removes lead paint through scraping, chemical stripping, or component replacement. All work follows EPA lead-safe work practices.
After removal, a thorough three-pass cleaning: HEPA vacuum all surfaces, wet wipe all surfaces, final HEPA vacuum. This ensures all lead dust is removed.
A third-party inspector collects dust wipe samples from floors, window sills, and window troughs. Samples are analyzed at a certified lab. Results must be below EPA clearance levels.
Upon passing clearance, the contractor provides: clearance test results, abatement records, and files the AF-5 Affidavit with HPD. DeLead NYC handles all documentation. Learn about our abatement services.
