604-757-2016Proper pressure washing before deck staining is essential for stain adhesion, colour consistency, and long-term durability. Dirt, mildew, old stain residue, and surface oxidation prevent new stain from penetrating the wood properly. Professional pressure washing prepares your deck surface so staining lasts longer, looks better, and protects the wood beneath.

Deck staining contractors know: the quality of surface preparation determines how long your stain lasts. Applying new stain over dirt, mildew, or old finish causes premature peeling and uneven color. WashTech provides professional pressure washing specifically for deck staining preparation, we remove all contaminants, old stain residue, weathered wood fibers, and mildew so new stain penetrates and bonds correctly.
Serving West Vancouver homeowners and deck staining contractors with wood preparation that meets industry standards. Proper prep ensures your stain investment lasts years longer.
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-compliant crew uses precise pressure for each wood species (cedar, redwood, pressure-treated).
We clean 1-2 weeks before staining begins, allowing wood to dry completely while staying contaminant-free.
We use biodegradable mildew treatments that prevent black spots from appearing under new stain within months.

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.
