Pressure Washing, Done Right

Whistler's freeze-thaw cycles and shaded, forested lots are ideal for moss, algae, and lichen, and left alone they make walkways slick and wear surfaces down. We pressure wash driveways, patios, walkways, retaining walls, garage floors, and fences across Whistler, Squamish, and Pemberton.

We match the pressure to the surface: high PSI for concrete, a gentler wide pattern for pavers so the jointing sand stays put, and hot water for oil and rust. For siding and composite decking we switch to soft washing instead, so nothing gets damaged, and all runoff is handled responsibly.

What to Expect from Our Pressure Washing Service

Our pressure washing service is designed to restore hard surfaces to their original condition. We adjust pressure levels based on the surface — concrete driveways can handle high PSI, while wooden decks and pavers require a gentler approach to avoid damage.

Before we start, we assess your property to identify the right technique for each surface. We use commercial-grade equipment with adjustable nozzles and hot water capability for stubborn stains like oil, rust, and embedded dirt. All runoff is managed responsibly.

Common surfaces we pressure wash include driveways, garage floors, walkways, patios, retaining walls, fences, and concrete foundations. For more delicate surfaces like painted siding or composite decking, we recommend our soft washing service instead.

Whistler's Climate and Your Hard Surfaces

The Sea to Sky corridor's freeze-thaw cycles, heavy rainfall, and shaded forest settings create ideal conditions for moss, algae, and lichen growth on hard surfaces. Left untreated, biological growth can make walkways dangerously slippery and accelerate surface deterioration. Annual pressure washing not only improves appearance but extends the life of your driveways, patios, and retaining walls. Properties in Squamish are particularly prone to algae growth due to higher rainfall.

Frequently Asked Questions

What surfaces can you pressure wash?

We pressure wash concrete driveways, walkways, patios, retaining walls, garage floors, fences, and foundations. For softer surfaces like wood decks or painted siding, we use our gentler soft washing method.

Will pressure washing damage my driveway pavers?

No. We adjust the pressure and nozzle for each surface type. Pavers receive a lower PSI setting with a wider spray pattern to clean effectively without disturbing the jointing sand.

How often should I pressure wash my driveway in Whistler?

We recommend annual pressure washing for most Whistler properties. Driveways and walkways in shaded areas or near forests may benefit from twice-yearly cleaning to keep moss and algae under control.
