Pressure Washing / Prep Work in Connecticut
Pressure washing and paint prep in New Haven: what the work involves, what to check before hiring, and how we score the 7 local businesses.
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.

Common questions about pressure washing / prep work
- How much does pressure washing before painting cost?
- For a typical house exterior, expect roughly $200 to $600 for washing alone, depending on size, height, and access. Full prep with scraping, sanding, and priming costs much more and is usually folded into the painting quote.
- How often does a house need pressure washing?
- Most exteriors need it every one to three years, and always before repainting. Shaded, damp spots that grow mildew may need it more often.
- What should I expect on the day?
- Crews cover plants and shield outlets and windows, then wash from the top down. The surface must dry fully, often 24 to 48 hours, before scraping, priming, or painting starts.
- How can I tell if the prep work was done well?
- Look for clean, firm edges where old paint was scraped and feathered, no gouged or fuzzy wood, filled and caulked gaps, and bare spots primed. Peeling or bubbling within a year or two usually points to poor prep.
