Replacing windows in pre-1978 housing can disturb lead-based paint on sashes, stops, trim, jambs, and nearby walls. For compensated work in covered housing, window replacement is specifically important under the EPA Renovation, Repair and Painting program; hire the right certified firm and require a written containment and cleanup plan.
Why windows deserve extra attention
Windows contain multiple painted surfaces that rub, strike, slide, and collect dust. Removing a unit can disturb more paint than the visible sash suggests. Opening walls or trim may reveal older layers, and exterior work can release chips to soil or adjacent property.
Do not assume a replacement-window crew is lead-safe certified because it is licensed for general construction. Ask for the firm certification and the certified renovator responsible for the job, then verify them with the relevant EPA or authorized-state program.
The federal RRP framework
The EPA Renovation, Repair and Painting program applies to many firms paid to disturb painted surfaces in pre-1978 homes and child-occupied facilities. It covers training, firm certification, occupant information, containment, prohibited practices, cleaning, verification, and records. The EPA program questions address window replacement and other common scenarios.
Do not rely on a small-area exemption without checking the specific activity. Window replacement is treated differently from measuring only a patch of disturbed paint. Testing or a recognized determination that affected components are not lead-based paint may change the analysis, but it must satisfy the applicable rule and be documented.
Authorized states and local governments can have their own certification, notification, permit, disposal, or clearance rules. Confirm the current jurisdiction before signing a scope.
What a credible proposal should define
The contract should identify the number and location of windows, interior and exterior trim included, wall or sill repairs, finish work, access, furniture movement, occupant protection, and who handles unforeseen deterioration. It should also explain:
- how the work area will be isolated;
- how floors, furnishings, landscaping, and soil will be protected;
- whether occupants must remain out of work areas;
- how components will be removed without unnecessary breakage;
- which tools and dust-control attachments will be used;
- how debris will be contained before leaving the area;
- how the area will be cleaned and checked;
- what records the owner will receive.
If children, pregnant occupants, pets, tenants, or neighboring units may be affected, discuss access and protection before work begins—not on demolition day.
Testing before work
A full lead-based paint inspection is not always required before a covered renovation, but reliable component testing can help define the scope and preserve useful property records. A consumer swab and a professional inspection have different limitations; see the test kit versus XRF comparison.
If testing will be used to exclude components from lead-safe requirements, ask who is authorized to make that determination, which exact surfaces are covered, and what written record will support it. Untested trim elsewhere should not be treated as negative by association.
Cleaning verification is not always clearance
RRP cleaning verification is a prescribed process after renovation. Clearance examination involves an independent visual assessment and environmental sampling under the program that requires it. They are not synonymous.
Ask what final step applies to your project, lease, funding source, local law, or hazard-control plan. If the contract promises “lead clearance,” require the proposal to name the standard, sampling professional, laboratory, pass criteria, and response to a failed result.
Red flags
- Dry scraping or power sanding with no containment or dust collection.
- Open windows or doors allowing debris to move beyond the work area.
- A crew that cannot identify the certified renovator.
- Plastic sheeting and debris left for the homeowner to manage without instructions.
- A claim that installing a new unit eliminates every historic lead hazard around the opening.
- No plan for exterior chips, contaminated soil, adjacent units, or weather.
Records to keep
Retain the firm certification, contract, lead test results, required pamphlet acknowledgment, work-practice documentation, change orders, photographs, cleaning-verification or clearance records, warranties, and component list. Future maintenance around the opening may disturb old paint that remains behind trim or finishes.

Does replacing one window trigger RRP?
Window replacement in covered pre-1978 housing is a significant RRP scenario and should not be assumed exempt based only on a small disturbed area. Confirm the current rule and any authorized-state requirements.
Can a homeowner replace a window personally?
Federal RRP firm rules focus on compensated work, but other state, local, rental, workplace, waste, and exposure requirements may apply. Lead-safe practices remain important regardless of who performs the work.
Should the family leave during window replacement?
That depends on the scope, containment, occupants, and project plan. No one should enter the controlled work area until the required cleaning and verification steps are complete.
Do new windows make the room lead-free?
No. Lead paint may remain on walls, trim, adjacent openings, exterior surfaces, or concealed layers. The project record should state exactly what was tested, removed, enclosed, or left in place.
