We work with West Vancouver deck staining professionals regularly. They know our cleaning creates surfaces that meet manufacturer prep requirements for warranty coverage.
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.
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).
We use biodegradable mildew treatments that prevent black spots from appearing under new stain within months.
We clean 1-2 weeks before staining begins, allowing wood to dry completely while staying contaminant-free.

New stain won't bond to old finish, dirt, or mildew. It peels within months. Proper surface preparation ensures stain penetrates wood and lasts 3-5 years instead of less than one year.
Ideally 1-2 weeks. This allows wood to dry completely (moisture prevents stain absorption) while staying clean. Staining immediately after washing traps moisture.
Pricing depends on deck size, wood condition, and old finish removal difficulty. We provide free on-site quotes. Call us for more information.
Most reputable staining contractors require proper prep for warranty coverage.
