Pressure Washing in Ontario and Fontana

Post-wildfire and post-Santa Ana pressure washing is one of the busiest scopes we run in the Inland Empire. Smoke residue, road dust, and pollen settle onto Ontario driveways, Fontana patios, and Hardie walls all across the corridor, and by mid-summer the film is heavy enough that any repaint bonded on top would fail early. Crews adjust pressure and tip size to the substrate so Hardie, stucco, painted-wood, brick, and concrete each get the right approach, and older or aged walls get a soft-wash rather than a heavy blast.

Older West End Ontario and Downtown Fontana homes tend to have chalkier painted-wood siding and older stucco that will not tolerate maximum pressure, while newer Ontario Ranch and Chino Hills builds can take a more aggressive wash. Concrete, pavers, and stamped hardscape each get a different pressure and detergent approach at the estimate, and hardscape work rinses cleanly around Inland Empire drought-tolerant landscape when the sequence is planned right.

Most standalone pressure-washing requests here are pre-listing cleanups, post-wildfire smoke removal, or pre-paint prep. When the goal is a full exterior repaint, the wash is scoped as the first day of the project so paint bonds to a clean substrate rather than sitting on a chalk-smoke-and-dust layer. Our writeup on long-lasting exterior paint treats pressure washing as step one for a reason.
