If you are planning renovations on an older house, test for lead-based paint before disturbing any painted surfaces. For those that need a lead hazard investigation with no lead-poisoned child, call Health Hazard Control at (919) 707-5950.
Trained professionals use a range of methods when checking your home, including:
Visual inspection of paint condition and location
Lab tests of paint samples
Surface dust tests
A portable X-ray fluorescence machine
Home test kits are available, but recent studies suggest they are not always accurate. Consumers should not rely on these tests before doing renovations or to assure safety.
