XRF lead inspections — calibrated, on-site, same-day.
X-Ray Fluorescence is the industry standard for lead paint identification in occupied properties. It's fast, non-destructive, and produces a definitive reading — surface by surface — that satisfies EPA, HUD and NYC HPD protocols.
What's in scope.
Below is the standard scope for an Envirex xrf inspections engagement. We size the project to the building — line-item, fixed-fee — and write the quote against this catalog.
Pre-inspection calibration.Each XRF unit is calibrated against NIST-traceable standards at the start and end of every shift, with calibration logs included in the report.
Component-by-component readings.Every painted component — walls, ceilings, doors, jambs, sills, baseboards, radiators, banisters — is read individually and recorded.
Friction & impact surfaces.Special attention to window stools, troughs, sashes and doors — the highest-risk components in NYC's pre-1960 housing stock.
Inconclusive resolution.When the XRF returns inconclusive, paint-chip samples are collected and sent to an AIHA-LAP accredited lab for spectrophotometric confirmation.
Same-day field summary.A field-level summary of positive and negative components is shared with the owner / agent on-site; the formal report follows in 24–48 hours.
Regulatory framework.
Every Envirex engagement is run against the regulator who will ultimately read the report. Here are the rules that shape xrf inspections work in New York.
EPA Lead-Safe Certified Firm.Envirex holds the EPA firm certification required to perform regulated lead inspections.
HUD Protocol XRF.Inspector calibration and procedure to the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards.
ASTM E1828.Standard practice for evaluating XRF performance — referenced in EPA, HUD and NYC HPD work.
NYC HPD Local Law 1 / 31.XRF is the testing modality required for annual investigation under LL1 and the one-time inspection program under LL31.
Best suited for.
Pre-abatement scoping, multi-unit surveys, schools, transaction-stage lead diligence, HPD investigation work.
What you receive.
Sealed and signed report in 24–48 hours. Field-level summary shared on-site.
