Deck Cleaning Ottawa: How to Prep Wood Decks for Staining
Grey, weathered decks need more than a quick rinse before staining. Learn how professional deck cleaning restores wood and helps stain last longer.
A grey, weathered deck isn't just an eyesore—it's a sign that UV rays and Ottawa's freeze-thaw cycles have broken down the wood's surface fibers. If you're planning to stain or seal your deck this season, proper cleaning is the single biggest factor in how long that finish will last.
Why a Garden Hose Isn't Enough
Weathered wood develops a fuzzy, oxidized "grey" layer of dead fibers on the surface. A hose rinse only moves surface dirt around—it doesn't remove this layer, which means stain applied on top won't bond properly and will peel or flake within a season.
Our Deck Cleaning Process
- Debris & Furniture Clearing: We clear the deck surface so every board gets even treatment.
- Wood-Safe Cleaning Solution: A specialized cleaner lifts mildew, algae, and grey oxidation without the splintering risk of high PSI.
- Controlled-Pressure Rinse: We use low-pressure, wide-fan tips calibrated for wood—not the narrow, damaging tips used on concrete.
- Brightening Treatment: For older decks, a wood brightener neutralizes the cleaner and restores the wood's natural color before staining.
Composite vs. Wood Decks
Composite decking doesn't need staining, but it still collects mold, pollen, and grime in its textured surface. We adjust pressure and cleaning solution specifically for composite materials to avoid damaging the cap layer.
When to Clean Before Staining
Clean your deck and let it dry for 48 hours minimum before applying stain or sealant. Rushing this step is the most common reason DIY staining jobs fail. Spring and early fall—when humidity is lower—are the best windows for deck staining in Ottawa.
Pricing & Service Areas
Deck cleaning starts at $199 for a standard residential deck. We serve Ottawa, Kanata, Orleans, Barrhaven, Nepean, and Stittsville. Ask about combining deck cleaning with your spring driveway and patio pressure washing.

Not with the right equipment. We use low-pressure, wide-fan tips and wood-safe solutions specifically calibrated for wood to avoid splintering or gouging.
