Painting the outside of your house: prep, paint and timing
Updated 2026-10-20
An exterior paint job lasts as long as its prep. Compare quotes on prep, paint and coats, not just price, and if your home was built before 1978, hire a lead-safe certified painter.
Prep is most of the job
- Pressure washing and letting the surface dry
- Scraping and sanding loose paint
- Repairing rotted wood and patching stucco cracks
- Caulking gaps and priming bare spots
- Protecting plants, windows and walkways
Older homes and lead paint
Homes built before 1978 may have lead paint. Painters disturbing it must follow the EPA's lead-safe (RRP) work practices and be certified. Ask for the certification before you sign.
When to paint
Late spring through early fall is the most reliable window in Silicon Valley: dry days and mild temperatures. Avoid painting just before rain or on very hot afternoons in direct sun.
Comparing quotes
- Which prep steps are included?
- Which paint brand and product line, and how many coats?
- Are trim, doors, gutters and the garage door included?
- What's the warranty, and what does it cover?
- Jobs of $1,000 or more need a C-33 Painting license; check it at cslb.ca.gov.
