Best Time of Year for House Washing in California

The short answer: any time you can stay above 50°F and let the surface dry. The longer answer depends on what you're trying to accomplish.

Spring (best overall)

Spring washes lift winter dust, pollen and the algae that grew over a damp winter. It also resets your exterior before the summer entertaining season.

Fall (great for prep)

A fall wash clears summer dust and gets the house ready for winter rain. Pair it with gutter cleaning for max impact.

After a rainy stretch

Algae and mildew grow fast after rain. Washing 2–3 weeks after a wet stretch is great timing.

Avoid extreme heat

Above 90°F, cleaning solutions can flash-dry on the surface and streak. We schedule early mornings on hot days.
