WHAT'S INCLUDED
Deck Washing details, clearly laid out.
Starting at $400, this service is built around a safer, more surface-appropriate process than what most people think of when they hear the word “pressure washing.”
Included
Starting at $400
Deck surface washing
Deck boards, steps, railings, and surrounding deck surfaces are treated with a lower-pressure / chemistry-first approach that better fits the material, the finish on top of it, and the condition the deck is in.
Organic buildup is killed at the root.
Designed around preserving the surface.
Landscaping care throughout the process
Included
Rinse and protect workflow
Surrounding greenery is rinsed and protected throughout the service to help ensure the process stays controlled and safe for nearby landscaping.
Not Included
Specialty stain exclusions
Deck Washing does not include iron stains, oxidation, efflorescence, or oil staining. Those issues may need dedicated specialty treatment.
PROCESS
Deck materials and finishes do not all respond the same way.
Using excessive pressure on deck boards, stairs, and railings can splinter surfaces, strip finishes, dull composite textures, and shorten material life. Glass House uses a softer, chemistry-assisted approach because deck cleaning should be tailored to the material itself — whether the surface is pressure-treated wood, cedar, redwood, painted wood, stained wood, composite, capped composite, or PVC decking.
Assess the material
Different decking materials respond differently, and cedar or more delicate wood surfaces may need even more care than standard decking.
Treat the buildup
The cleaning solution is applied so it can help break down algae, mildew, moss, and grime before the rinse phase.
Rinse more carefully than concrete
Deck surfaces are not treated like driveways. The rinse phase is controlled around the material and the finish the deck needs.
WHY METHOD MATTERS
A cleaner result starts with using the right method for the material.
The method is a majority of the value. Good exterior cleaning is not just about blasting something until it looks lighter.
Too much pressure can damage the surface
Decks are one of the clearest examples of why pressure should not be the default answer for every exterior material. If too much pressure is used, the surface will be stripped permanantly.
Cleaner outdoor living space changes how the property feels
A washed deck can make the backyard feel more usable, more cared for, and more ready for guests.
It is a natural seasonal refresh service
Deck Washing is especially useful before summer gatherings, listings, and after long seasons of pollen and organic buildup.
DECK MATERIALS & FINISHES
Different deck materials and finishes call for different cleaning decisions.
The safest cleaning process depends on what the deck is made from and what is on top of it. That includes pressure-treated wood, cedar, redwood, painted wood, stained wood, resurfaced coatings, composite decking, capped composite decking, and PVC-style boards.
Bare or weathered wood
Wood can be cleaned well, but it is easier to damage than people think. Aggressive pressure can raise grain, rough up fibers, and shorten the life of the surface.
Painted or coated decks
Painted wood and resurfaced deck coatings need a more finish-aware approach. If the coating is already failing, the process has to respect that reality.
Composite-family decks
Composite, capped composite, and PVC-style decking products often have manufacturer-specific care guidance. That is one more reason Glass House leans toward softer, more material-sensitive cleaning instead of defaulting to aggression.

FAQ
Deck Washing questions homeowners ask before booking.
Decks generate a lot of confusion because wood, coatings, composite surfaces, and PVC-style boards do not all behave the same way. The FAQ should make that obvious.
What does Deck Washing remove?
Deck Washing targets algae, mildew, mold, moss, lichen, cobwebs, dirt, pollen, and similar organic buildup on deck surfaces.
Do you clean all deck materials the same way?
No. Pressure-treated wood, cedar, redwood, painted wood, stained wood, resurfaced coatings, composite decking, capped composite decking, and PVC-style decking can all require a different level of care.
Do you pressure wash decks the same way you pressure wash concrete?
No. Decks are treated with a much more careful lower-pressure or no-pressure process than durable flat concrete.
Can painted or stained decks be cleaned?
Yes, but painted, stained, or coated decks need a finish-aware approach. If the coating is failing, peeling, or fragile, the cleaning plan needs to account for that.
Can composite decks be cleaned safely?
Yes. Composite-style decks still need the right chemistry, brush choices, and rinse discipline. They are lower-maintenance than wood, but not maintenance-free.
How often should a deck be washed?
That depends on shade, moisture, tree coverage, pollen, and how quickly the deck shows algae or grime. Many homeowners book before summer use, events, or when the deck starts looking dull or slick.
Material matters
The page is intentionally written to show that a cedar deck, a painted wood deck, and a capped composite deck should not all be treated the same way.
