The best time to power wash a house in Michigan is from late spring through early fall, roughly May through October. Temperatures are above freezing, siding dries quickly, and the pollen, mildew and grime from the previous season can come off before it sets in.
Why Spring Is the Best Time to Power Wash a House
Michigan winters leave behind road salt, dirt and green algae on north-facing siding. Washing in spring removes it early, makes your home look its best for summer, and gives you a clean surface if you’re planning to paint or stain.
Is Fall a Good Time Too?
Yes. A fall wash removes summer pollen, cobwebs and mildew before winter. Moisture trapped under grime through a long winter is what lets mold spread, and the U.S. EPA explains that controlling moisture is the key to controlling mold.
When Not to Power Wash
- When temperatures are near or below freezing, since water can freeze on siding, decks and walkways
- Right before heavy rain, if you’re planning to paint or stain afterward
- On very windy days, which make soft-wash solutions harder to control
Soft Washing vs Power Washing Your Siding
Most siding should be soft washed with low pressure and cleaning solutions, not blasted. High pressure can force water behind vinyl siding and strip paint. Read more about soft washing vs pressure washing.
