Pressure fuzzes wood fiber
High pressure raises and tears soft grain fibers, leaving a fuzzy, damaged surface that no longer takes stain evenly. Wood jobs run at lower PSI with wider fan tips and rely more on chemical dwell time than force.

Deck & Fence Cleaning Cost Calculator — wood-safe pricing, not guesswork.
Turn deck or fence area, wood condition, and brightener treatment cost into an accurate cleaning price. Wood needs lower pressure and different chemistry than concrete pressure washing (or power washing), especially when the job is prep for staining.

Deck & fence cleaning guide
Why wood needs a different approach than concrete
Pre-stain prep is a different job than washing
Removing old finish, tannin bleed, and mill glaze to fully open the grain takes longer and often needs an oxalic acid brightener step after the initial clean, which is why it carries the highest job-type multiplier.
Composite decking has its own rules
Composite boards can scratch or streak under high pressure and generally need a soft wash approach and manufacturer-approved cleaner rather than the same chemistry used on real wood.
Check fasteners and board condition first
Popped nails, spongy boards, and loose railings are liability issues, not cleaning issues. Note them before starting and put them in writing so the customer knows they were pre-existing.
Matching job type to price
Routine wash, graying wash, and pre-stain prep are three different jobs
Routine wash
Removes dirt, pollen, and light surface mildew at close to the full rated production rate. This is a maintenance-frequency job, not a restoration job, and should be priced accordingly.
Graying wash
Weathered, UV-grayed wood needs a stronger cleaner and slower passes to lift oxidized fibers evenly, without over-brightening some boards while leaving others gray.
Pre-stain prep
The customer is paying for a stain-ready surface, not just a clean one. Budget time for a brightener neutralizing rinse and a full dry period before staining can even begin — that dry time is a scheduling constraint, not a labor cost, but it belongs in the customer conversation.
Track the finish, not just the wash
If you also apply stain or sealer, price that as a separate line item using material coverage rates, not folded into the cleaning price above.
