Laboratory-grade dust wipe sampling for NYC lead clearance. NYS ELAP-certified labs, 3-5 day turnaround. Pass/fail clearance determination.
When dust wipe testing is required and how to achieve clearance.
After work that disturbs more than two square feet of lead paint in a pre-1960 building where a child under 6 lives, the area must pass dust wipe clearance before it is reoccupied, and owners must give tenants the results.
Applicable NYC lead-safe work rules may require post-work dust wipe clearance when painted surfaces are disturbed. The trigger and sampling requirements depend on the work, property, and any agency order:
For NYC clearance samples collected on or after November 5, 2026, results must be below the following limits. Required records and agency review remain separate. See NYC Health clearance guidance:
μg/ft² on Floors
μg/ft² on Windowsills
μg/ft² on Window Wells
EPA-certified sampling with NYS ELAP laboratory analysis.
Before sampling, we verify that work is complete, debris has been removed, and the unit has been cleaned. Sampling can only occur after final cleanup.
Our EPA-certified technicians collect dust wipe samples from floors, window sills, and window troughs using standardized sampling protocols. Each wipe is individually sealed and labeled for laboratory analysis.
Samples are sent to a New York State ELAP-certified laboratory for lead content analysis. Lab results are typically available within 3-5 business days.
You receive a comprehensive lab report with pass/fail determination. If clearance is achieved, we assist with HPD filing so tenants can re-occupy. If failed, we provide re-cleaning and re-testing recommendations.
If any dust wipe sample exceeds clearance standards, additional cleaning and re-testing are required before tenants can re-occupy.
Note: Re-testing after failed clearance typically requires 24-48 hours for cleaning and drying before new samples can be collected. Budget time accordingly to avoid tenant displacement.
Transparent pricing for clearance testing. Re-testing discounted if needed.
Re-Testing: 50% discount if initial clearance fails and re-cleaning is performed
Schedule post-work dust wipe clearance testing when the applicable rules or agency order require it.
