How often to exterior pressure wash in an Airbnb

Every 365 days (~12.2 months). Cost: $200–$500. Best left to a pro.

How often to pressure wash the exterior of an Airbnb

Annually — every 365 days, in spring before peak booking season. Coastal, humid, or shaded properties should run every 180 days because of mildew growth rate.

Cost is $200–$500 per property for a pro wash. A 2,000-sq-ft single-story house with a driveway runs $250-$400. Add a deck or large patio and you’re at $400-$600. Multi-story or stucco/brick adds $100-$200.

Why pressure washing matters more for STR

The first photo on your listing is the front exterior. The first thing a guest sees when they pull up is the front exterior. Both moments form the entire “is this listing worth the price?” judgment.

Dirty siding does specific damage to that judgment:

Mildew streaks on white siding — reads as neglected
Algae on the north side roof or stucco — reads as old
Spider webs under eaves — reads as not-recently-maintained
Discolored concrete walkways — reads as low effort

None of these are visible problems individually. The cumulative effect crushes your booking conversion rate.

The structural angle matters too: mildew on siding accelerates the deterioration of the paint or stain coating. A house that should go 5 years between exterior paint refreshes becomes a 3-year property if it never gets pressure washed.

What a real exterior pressure wash includes

A proper annual wash covers seven surfaces:

Siding (all sides). Soft-wash chemistry (sodium hypochlorite + surfactant) at low pressure for vinyl, fiber cement, and painted wood. NOT high-pressure — that drives water behind the siding.
Soffits and eaves. Spider webs, wasp nests, dirt. Low-angle spray from below.
Gutters (exterior face). “Tiger striping” — those vertical black streaks below gutters — wipes off here.
Trim and window frames. Soft-wash; high pressure damages caulk and paint.
Driveway and walkways. Concrete: high pressure (3,000+ PSI) with a surface cleaner attachment for even results. Pavers: medium pressure to avoid blasting out joint sand.
Deck or patio. Wood: low pressure + deck cleaner; high pressure shreds soft wood grain. Composite: low pressure + manufacturer-approved cleaner.
Fence (front + sides visible from listing photos). Wood or vinyl. Match pressure to substrate.

Roof washing is a separate task (and a separate quote) — most pressure washers don’t walk on roofs. Soft-washing a roof from a ladder + extension wand is the right method.

DIY vs pro

DIY makes sense if you already own a pressure washer (3,000+ PSI gas unit ideal; 2,000 PSI electric workable for concrete only). Cost: $0 if you own the unit, $80-$120/day rental.

Pro makes sense if:

You have vinyl/fiber-cement siding (need soft-wash skill, not raw pressure)
The house is 2+ stories
You have a stained deck or wood fence (overspray on siding ruins paint; under-spray on the deck strips stain unevenly)
You hate ladders

Safety angle: high-pressure injection injuries are serious — pressure washer wands can inject contaminated water through skin. Don’t aim at body parts, ever. Don’t use a wand from a ladder — the kick-back has put people in the hospital.

When to upgrade the cadence

Coastal markets (salt air) — every 180 days
Humid southeast / Gulf Coast — every 180 days
Properties with significant tree cover (north-side algae) — every 180 days
White or light-colored siding — every 180 days; mildew shows
Deck stripping — every 730 days; full strip-and-restain is a separate cycle from annual wash

The “before pro photos” tie-in

If you’re scheduling a photo refresh, the exterior wash is the prep step. Sequence: wash → 24-hour dry → photos at golden hour. The conversion-rate lift on a re-shot exterior pays for the wash + photographer in a single peak weekend.

Signs you missed it

Black or green streaks running down siding below gutters
Dark patches on the north side of the roof
Discolored concrete in the driveway compared to under-cover sections
Spider webs visible in listing photos
Guest review or message mentioning “exterior” in any capacity
