Stain contractors trust our prep work
We work with West Vancouver deck staining professionals regularly. They know our cleaning creates surfaces that meet manufacturer prep requirements for warranty coverage.
Removes old stain and sealers completely
New stain won't bond over old finishes. Our pressure washing strips away weathered coatings and damaged wood fibers, exposing clean wood that absorbs stain evenly.
Controlled pressure prevents wood damage
Too much pressure creates splinters and "fuzzes" wood grain. Too little leaves contaminants. Our WorkSafeBC certified crew uses precise pressure for each wood species (cedar, redwood, pressure-treated).
Pressure Washing Different Deck Materials
Cedar & Softwood Decks:
- Lower pressure
- Prevents fiber damage
Pressure-Treated Wood
- Removes mill glaze
- Improves stain bonding
Older / Previously Stained Decks
- Controlled pressure + detergents
- Avoids patchy absorption
Timing coordinated with staining schedule
We clean 1-2 weeks before staining begins, allowing wood to dry completely while staying contaminant-free.
Kills mildew at the root
We use biodegradable mildew treatments that prevent black spots from appearing under new stain within months.
