Maintaining encapsulated surfaces
Encapsulated or enclosed lead paint is still there, so treat it as a known condition. Look over coated areas from time to time for chips, scuffs and water damage, and repair breaks promptly. The Department of Labor advises that the owner supervise maintenance and contract workers near enclosed or encapsulated paint. A later remodel that cuts into those surfaces in a pre-1978 home falls under the EPA renovation rule, and a sale or lease brings the federal duty to disclose known lead-based paint.
For surfaces too worn to coat, compare lead paint removal for older homes. Windows and doors are generally better replaced or stripped, as explained under lead-painted windows and doors. See Kyle Lead Paint Removal for the full range.
