Deck & Patio Cleaning, pressure matched to the board
Careful restoration for wood, composite and stone living spaces.
Deck & Patio Cleaning — done properly
Decks, patios, pergolas and porches cleaned at the right pressure for the material. We lift the slick green film, graying and mustiness from wood and composite, and prep surfaces properly if you plan to stain or seal.
What deck & patio cleaning is up against in the Northwest
Wood vs. composite
Cedar and pressure-treated lumber want low pressure and a brightener; Trex and composite want detergent and almost no pressure. The wrong call furs the wood or voids the warranty.
That slick green film
Shaded Northwest decks grow an algae film that gets genuinely dangerous when wet. Clearing it is a safety job as much as a looks job.
Prep that respects the next coat
If you are staining or sealing after, the surface has to be cleaned and neutralized correctly or the finish will not take.
Every job, every time
- Wood, composite, Trex, concrete, flagstone
- Railings, spindles and lattice detailed
- Pre-stain / pre-seal prep available
- Furniture moved and replaced
Four steps, no surprises
Identify & test
We confirm the decking material and test an inconspicuous spot to set the pressure and solution.
Apply & dwell
A wood-safe cleaner is applied to the deck, rails, spindles and lattice and left to break down the growth.
Clean at the right pressure
Low pressure for wood, gentle detergent rinse for composite — worked with the grain, board by board.
Brighten & rinse
Wood gets a pH-balancing brightener to restore tone and open the grain for stain; everything is rinsed and the furniture replaced.
Most residential decks run $99–$500 depending on size, height, railing detail and whether a brightener is needed. Add brightening for stain prep at a set per-square-foot rate.

Before you book
Can you clean my composite / Trex deck?
Yes, and it needs the gentle approach. Composite is cleaned with detergent and very low pressure — high pressure can permanently mar the surface and void the warranty.
Do you stain or seal too?
We do the cleaning and brightening prep to a stain-ready standard. We can coordinate the sealing or hand it back to you once the wood has dried out — usually 24 to 48 hours.
Will it get the graying out of my cedar?
Cleaning plus a brightener removes surface graying and mill glaze and brings back a lot of the natural tone. Deep weathering that has gone into the fiber needs sanding, which is outside this service.
