Key takeaways
- Homes built before 1978 may have lead paint on siding and trim.
- Some older siding and sheathing products contained asbestos.
- Testing tells you what you have before work begins.
- Safe handling protects your family and the crew.
Lead paint
Paint made before 1978 may contain lead, and exterior trim and siding are common places to find it. Scraping, sanding or demolishing painted surfaces can release lead dust and chips. Federal rules require lead-safe work practices when contractors disturb lead-based paint in many older homes, and trained firms follow them.
Asbestos
Some older cement siding, shingles, roofing and wrap products contained asbestos. Intact material is generally less risky than damaged or broken material, but breaking or sawing it can release fibers. If you suspect your siding contains asbestos, do not cut or break it. Have it tested and follow proper removal and disposal rules.
Testing first
A qualified lab or inspector can test paint and siding samples. Testing before demolition lets you plan for containment, protective measures and disposal, and avoids exposure and delays. Ask your contractor how they handle suspect materials.
Safe work
Safe practices include containing the work area, wetting materials, avoiding power sanding and dry scraping, using proper protective equipment, cleaning up with suitable vacuums and wipes and disposing of waste correctly. Keep children and pets away from the work area.

Quick answers
Is my siding likely to contain asbestos?
Siding installed decades ago sometimes did. Testing is the only way to know.
Can I remove lead paint myself?
Safe removal requires training and methods that control dust. For older homes, a qualified professional is the safer choice.
Does covering old siding solve the problem?
Sometimes, but it does not address underlying damage, and a test and a professional's advice help decide.
