Paint fails early when the surface underneath is dirty, chalky, or loose. Pressure washing and prep work is the step that fixes that: washing off mildew, dirt, and oxidation, scraping and sanding failing paint, spot-priming bare wood, and caulking gaps. New Haven's older housing stock, from wood-sided triple-deckers to Victorians in East Rock and Westville, often has several layers of old paint, so prep tends to decide how long the new coat lasts.
What to look for
- A pressure setting matched to the surface. Wood and old brick need low pressure or a soft wash, not a blast.
- A plan for drying time before priming or painting, usually a day or two.
- Lead-safe practices on homes built before 1978 (EPA RRP certification).
- A written scope that lists scraping, sanding, priming, and caulking separately.
