How Often Should You Wash Your House? A Realistic Schedule by Surface

Waiting until it looks bad means you already waited too long. Here is the schedule that keeps costs down.

Exterior cleaning is maintenance, not cosmetics. Organic growth holds moisture against your building materials, and moisture is what actually destroys them. The schedule below keeps you ahead of it.

The general schedule

• House siding soft wash: every 12–18 months
• Driveways, walkways, and pool decks: every 12 months
• Paver and concrete sealing: every 2–4 years
• Decks and fences: every 12–24 months, cleaned before any re-stain
• Commercial storefronts and sidewalks: monthly to quarterly

Signs you are already overdue

• Black or green streaking on shaded walls and soffits
• Concrete that is noticeably darker than it was, or slippery when wet
• Green film on screen enclosures and pool cages
• Wood that has gone silver-gray and feels rough
• Weeds or ants coming up through paver joints

Why humidity changes the math

Warm, humid, rainy climates accelerate everything. Algae and mildew colonize shaded surfaces within months, not years. If your property has heavy tree cover, irrigation spray hitting the walls, or a north-facing wall that never gets sun, plan on the shorter end of every interval above.

Cheaper to maintain than to restore

A routine wash is a fraction of the cost of repainting stucco, replacing rotted fascia, or restoring a stained driveway. Recurring maintenance is the least expensive way to own an exterior.
