Best Time of Year to Pressure Wash Your House
Timing matters. Here's a season-by-season guide for Delaware homeowners, with tips specific to our coastal climate.
The Short Answer
For Delaware homes, spring and fall are the ideal seasons for exterior cleaning. Spring removes winter grime and pollen buildup, while fall clears summer algae and prepares your home for the holidays and cooler months.
That said, professional cleaning can be done almost any time of year—the "best" time is often simply when your home needs it. If you see visible algae, mold, or dirt buildup, don't wait for a specific season.
Season-by-Season Breakdown
Spring (March–May)
ExcellentThe best time for most Delaware homeowners. Pollen season coats everything, and winter grime has had months to accumulate. Cleaning in spring refreshes your home for summer and removes mold that grew during the damp winter months.
Summer (June–August)
GoodSummer works well, especially early summer before the peak heat. Warm temperatures help cleaning solutions work faster. However, high humidity means algae can return more quickly, and scheduling can be busier.
Fall (September–November)
ExcellentAnother prime window. Cleaning in fall removes summer algae buildup and prepares your home for winter. It's also ideal if you're listing your home for sale or hosting holiday gatherings.
Winter (December–February)
LimitedFreezing temperatures can make pressure washing impractical or risky. However, Delaware's milder winter days (above 40°F) can still work for soft washing. We schedule winter jobs on suitable days when conditions allow.
Delaware-Specific Considerations
Living in Sussex or Kent County means your home faces challenges that homeowners further north or inland don't experience as intensely:
Pollen season (March through May) blankets everything in a yellow-green film. Cleaning right after pollen season ends gives you the longest stretch of clean surfaces.
Hurricane and storm season (June through November) can deposit debris, dirt, and organic matter on your home. A post-storm cleaning can prevent staining from becoming permanent.
Salt air from the Atlantic is a year-round factor for coastal communities like Rehoboth Beach, Lewes, and Bethany Beach. Regular cleaning removes salt deposits that can corrode and discolor surfaces over time.
