Your home’s exterior faces the elements every day—rain, sun, wind, and debris. This raises a common question: how often should you pressure wash your house? While the answer depends on climate, material, and exposure, establishing a schedule helps preserve your home’s beauty and structure.

This guide outlines when and why to pressure wash for optimal upkeep.

Why Pressure Washing Is Necessary

Pressure washing removes:

• Dirt and dust buildup
• Mold, mildew, and algae
• Pollen and air pollution residue
• Insect nests and webs

These contaminants don’t just look bad—they can eat away at materials, shorten the life of paint and siding, and even affect air quality.

Regular cleanings reduce maintenance costs and increase your home’s value.

General Rule of Thumb

In most areas, it’s best to pressure wash your home once every 12 to 18 months. However, specific surfaces and environments may require more frequent care.

Key factors include:

• Local climate (humid vs. dry)
• Proximity to trees or wooded areas
• Siding material (vinyl, brick, stucco)
• Urban vs. rural setting

For example, homes in humid Southern states may need cleaning every six months to prevent algae growth.

Best Times of Year to Pressure Wash

Spring

Spring is ideal for removing winter buildup, especially in regions that experience snow or storms. It preps your home for summer curb appeal and catches any mildew early.

Fall

A fall cleaning helps remove pollen, bugs, and debris that gathered through summer. It also prevents mold from setting in during colder, damper months.

Pro Tip: Avoid freezing weather, as water left in cracks or crevices can expand and cause damage.

Surface-Specific Recommendations

Siding

Pressure wash vinyl, aluminum, or composite siding once per year. Wood siding may need soft washing instead to prevent damage.

Roof

Most roofing should be cleaned every 2 to 3 years with a soft wash technique. Algae and black streaks shorten shingle life and reduce efficiency.

Driveways and Walkways

Clean driveways and sidewalks twice a year. High-traffic areas may need more frequent attention to remove oil stains and tire marks.

Decks and Fences

Wooden structures should be washed every 1 to 2 years, depending on weather exposure and shade. Always reseal after cleaning to protect against moisture.

Warning Signs It’s Time to Pressure Wash

• Green or black stains from mold or algae
• Chalky residue on painted surfaces
• Cobwebs under eaves
• Foul or musty odors near the exterior
• General discoloration or dullness

Don’t wait for visible damage. Preventative washing is easier and more affordable than repairs.

Frequency by Climate

Living in a forested or shaded area? You may need more frequent washes due to moss and sap accumulation.
