Lead Clearance Testing

Independent post-remediation dust wipe testing performed to verify cleanup efforts and support project completion.

What Is Lead Clearance Testing?

A kitchen corner with a plastic sheet covered wall, warning signs for danger and caution, a small counter with potted plants and supplies, a wheel cart with items, a trash can, and a cardboard box on the floor.

Lead clearance testing is performed following lead hazard reduction, remediation, renovation, or abatement activities to evaluate whether cleanup objectives have been achieved. The process typically includes a visual evaluation and dust wipe sampling from designated surfaces.

What to Expect During Our Visit

Part of a room under renovation with taped corners, a white wall, and an unfinished floor.

We will review the project scope, evaluate the work area, and collect dust wipe samples from representative surfaces in accordance with applicable regulations and project requirements. Sampling locations vary depending on the scope of work and clearance objectives.

What Happens After Clearance Testing?

A house with beige siding and multiple windows, some with blue painter's tape, a staircase leading up to the porch, greenery nearby, and a cloudy sky.

Dust wipe samples are submitted to an accredited laboratory for analysis. Once testing is complete, findings are summarized in a report documenting the sampling performed, laboratory results, and applicable clearance findings.

When Is Lead Clearance Testing Recommended?

Room under renovation with yellow walls, a window, and construction materials, including a trash bin and wooden wall framing.

Lead clearance testing is commonly performed following lead hazard reduction activities, lead-based paint remediation, renovation projects, and other work involving lead-containing materials. Clearance testing provides independent verification that cleanup efforts have been completed successfully.
