Pressure Washing 101: Driveways, Decks, and Siding in the Okanagan

After an Okanagan winter and a heavy pollen season, driveways, decks, and siding can look tired and grimy. Pressure washing is one of the most satisfying ways to refresh a property, but the wrong pressure or technique can damage surfaces. Here is what to know before you fire up the wand.

Driveways and concrete

Concrete and paver driveways handle high pressure well, which makes them the easiest place to start. Work in overlapping passes to avoid streaking, and use a surface cleaner attachment for an even finish. Oil stains and stubborn algae may need a degreaser or detergent first.

Decks and wood

Wood is far more delicate. Too much pressure will gouge and splinter the boards. Use a lower pressure, a wider fan tip, and keep the nozzle moving and at a distance. Always go with the grain. For older or softwood decks, sometimes a gentle wash and a brush beats blasting it.

Siding and exterior walls

Vinyl siding cleans up nicely, but you should spray downward, not upward, to avoid forcing water behind the panels. Keep the nozzle well back, and never aim high pressure at windows, vents, or light fixtures. Stucco and certain finishes need a soft wash approach with detergent rather than raw pressure.

• Use the right tip and pressure for each surface
• Keep the nozzle moving to avoid concentrated damage
• Protect plants, lights, and outlets before you start
• Spray siding from above to angle water away from seams

When to hire a pro
