The right method for the job

Low-pressure wash with wood cleanerCleaning method

Is it time for deck cleaning?

  • Gray, weathered boards
  • Green or black growth and slippery spots
  • Stain that is peeling or worn through
  • Dark spots under planters and furniture
  • Mildew between composite boards

Why it gets dirty

  • Sun breaking down the wood surface (it turns gray)
  • Shade, leaves and moisture feeding mildew
  • Old stain or sealer wearing unevenly
  • Pollen and dirt trapped in the gaps

Easy upkeep between cleanings

  • Clear the gaps between boards with a putty knife so water drains
  • Sweep often and keep leaves off the deck
  • Move planters and rugs now and then
  • Check for loose boards, nails and soft spots before anyone washes it

Not sure what you're looking at? The free stain identifier and safe pressure guide explain each stain and surface.

Why more pressure isn’t better

  • Furry, gouged wood and lap marks from too much pressure
  • Water and grime blasted onto the house siding
  • Using chlorine bleach on wood, which can damage fibers and fasteners
  • Washing composite decking in a way that voids its warranty

Deck Cleaning: frequently asked questions

How much does deck cleaning cost in SeaTac, WA?

Deck Cleaning typically costs $250-$600 for a typical 200-400 sq ft deck, and usually takes 2-4 hours. The exact price depends on the size and condition, and you get it before any work starts. Call (555) 010-0000 for a free quote.

Do you use high pressure for deck cleaning?

Deck Cleaning is done with low-pressure wash with wood cleaner. Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.

Is deck cleaning safe for my plants and pets?

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.

How often should I schedule deck cleaning?

Once a year. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.

What if it rains on the day?

Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
