Pressure washing and prep work is the step that decides whether a paint job lasts five years or fifteen. Before any primer or topcoat goes on, siding, trim, brick, and masonry need to be stripped of mildew, chalking paint, pollen film, and grime, especially in New Haven's mix of coastal humidity, salt air near the Sound, and old triple-decker and Victorian housing stock where lead paint and soft clapboard are common concerns. Good prep also includes scraping loose paint, spot-priming bare wood, caulking gaps, and sometimes light sanding, not just a rinse with a hose.
We've evaluated 7 pressure washing and prep contractors serving the New Haven area. When you're comparing them, look for a few things beyond price: do they adjust water pressure for the surface (wood and old mortar need far less PSI than concrete or vinyl), do they use soft washing with a cleaning solution rather than blasting bare wood, do they follow EPA RRP lead-safe practices on pre-1978 homes, and do they carry liability insurance in case a window or gutter gets damaged. A contractor who walks the exterior with you first and flags rot or failing caulk before quoting is usually more careful than one who just gives a flat per-square-foot number over the phone.
Our scoring weighs verified customer feedback, how consistently a company shows up and finishes on schedule, and signals of proper technique and insurance, so you can compare these 7 businesses on more than star count alone.
