Spring is the best time for a full exterior reset in Kitchener-Waterloo. After 5 months of salt, sand, freeze-thaw cycles, and road grime, most home exteriors are ready for a thorough clean. Here's the right approach for your first spring pressure wash — what to do first, how to do it safely, and how to get the most from the season.
When to Start
In KW, spring pressure washing season typically begins in mid-April when temperatures are consistently above 5°C and the risk of overnight freezing is low. You want surfaces warm enough to dry properly after washing — washing in near-freezing temperatures can leave moisture that re-freezes overnight and causes issues. Late April through May is ideal for most exterior cleaning.
Priority Order for Cleaning
When planning a full exterior spring clean, work top-to-bottom and largest-to-smallest: roof and gutters first (if applicable), then house siding, then hardscape surfaces (driveway, walkways, patio), then decks and fencing last. This order ensures debris from higher surfaces doesn't contaminate already-cleaned lower surfaces.
Driveway and Walkways
Your driveway and walkways accumulate the most visible winter residue. Salt staining, oil marks, tire tracks, and grit are all concentrated here. Start with a degreaser pre-treatment for oil spots, let it dwell, then pressure wash from the street edge back toward the house (directing dirty water away from the cleaned house siding you'll do next). Sidewalks should be approached similarly — they carry municipal road salt from sanding/plowing operations.
Deck and Patio
Decks are at their most vulnerable to organic growth in spring — they've been damp and cold all winter, creating ideal conditions for algae, mould, and mildew. A spring deck wash removes this biological film and is especially important before any deck staining, painting, or sealing work. Use appropriate pressure for the deck material — composite decking requires lower pressure than pressure-treated wood. Natural cedar and redwood are also pressure-washed at lower settings than treated pine.
Pro Tip: Pressure wash your deck with the grain of the wood, not against it. This avoids raising the wood grain and creating a rough texture. For composite decking, check the manufacturer's pressure washing guidelines — some composites have lower pressure limits than you might expect.
House Siding
Vinyl and aluminum siding accumulates winter grime, biological growth, and oxidation. A spring siding wash with appropriate low-to-moderate pressure and a cleaning solution removes this deposit and brightens the entire appearance of the home. For significant algae or mould, this may transition from pressure washing to soft washing territory, depending on the extent.
