Pressure Washing in Corona, CA

Corona is hotter and windier than the coast side of the hills, and that changes what pressure washing in Corona involves. Summer highs average in the low to mid 90s and can top 100°F. The record high is 118°F. Santa Ana winds blow mainly from October to December. Between the heat, the wind and long stretches without rain, dust ends up on solar panels, tile roofs, stucco walls and every slab of concrete on the lot.

Solar panels lose output under dust

With that much sun, plenty of Corona homes and businesses have solar. A layer of dust, pollen and bird droppings blocks light from reaching the cells. We clean panels with soft brushes and purified water at low pressure, never a pressure washer tip held close to the glass, which can damage seals. A good time to clean is after the fall wind events and again in late spring before the hottest months.

Roofs and walls after the winds

Wind-blown dust settles in the grooves of tile roofs and in stucco texture, and when the first rain comes it can leave streaks. Roof soft washing uses a cleaning solution at low pressure to remove dust, streaks and organic growth without breaking tiles. House washing follows the same idea for walls: low pressure, the right cleaner and a top-down rinse. If your area was close to a fire, the same process clears ash film. The 2008 Freeway Complex Fire started at the Yorba Linda and Corona city line, a reminder that the canyons nearby burn.

Cold mornings too

Corona winters are colder than much of Southern California, with frost on some mornings. The record low is 19°F. For cleaning, that means we schedule winter jobs for late morning or afternoon so water does not sit on shaded walkways and freeze.

Neighborhoods built since the 1980s

Before the 1980s, Corona was largely agricultural, with citrus orchards, ranches and dairy farms. High prices in Los Angeles and Orange counties drove rapid development, and by the late 1990s the city was considered a major suburb of Los Angeles. The population reached 157,136 at the 2020 census across 49,584 housing units. Corona Hills is the largest neighborhood by area at 2.91 square miles, and Sierra Del Oro covers 2.45 square miles. Many homes from those growth years now have 25 to 40 years of grime, fading concrete and roofs that may never have been cleaned.

Busy households, heavy driveway use

Corona households average 3.22 people, according to Census estimates. More people usually means more cars, more foot traffic and more stains on the driveway and garage apron. About 63.8% of homes are owner-occupied, with a median value of $700,700.

Commercial and industrial sites

Corona is served by the 91 freeway, Interstate 15 and State Route 71, and the businesses along those corridors include retail centers, offices and industrial buildings. We clean loading docks, dumpster areas, building fronts, drive-thrus and parking structures. Work can be scheduled at night or on weekends, and we capture or redirect wash water so it does not go to the storm drain.
