Why it matters here

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.

What's included

Every job, every time

  • Wood, composite, Trex, concrete, flagstone
  • Railings, spindles and lattice detailed
  • Pre-stain / pre-seal prep available
  • Furniture moved and replaced
How it works

Four steps, no surprises

01

Identify & test

We confirm the decking material and test an inconspicuous spot to set the pressure and solution.

02

Apply & dwell

A wood-safe cleaner is applied to the deck, rails, spindles and lattice and left to break down the growth.

03

Clean at the right pressure

Low pressure for wood, gentle detergent rinse for composite — worked with the grain, board by board.

04

Brighten & rinse

Wood gets a pH-balancing brightener to restore tone and open the grain for stain; everything is rinsed and the furniture replaced.

What it costs

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.

Deck & Patio Cleaning FAQ

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.
