Introduction

Pressure washing is one of the fastest ways to refresh your home’s exterior — but it’s also one of the easiest to get wrong. Too much force, the wrong nozzle, or cleaning the wrong surface can lead to cracks, scratches, or water damage.

For Invermere homeowners, the question isn’t “should I pressure wash?” but “what’s safe to pressure wash, and what isn’t?”

Surfaces that are safe to pressure wash

  • Concrete driveways and sidewalks → Durable enough for higher PSI.

  • Stone pavers → With the correct nozzle setting.

  • Vinyl siding → Safe at low pressure with the right angle.

  • Decking (composite or well-sealed wood) → Only at low settings, with even passes.

Surfaces that are not safe to pressure wash

  • Wood siding or older decks → Can splinter or strip away protective finishes.

  • Asphalt shingles → Pressure can tear granules off and shorten roof life.

  • Windows and screens → High-pressure jets can shatter glass or warp frames.

  • Delicate masonry or painted surfaces → Risk of etching and peeling.

Why Invermere homes are unique

Mountain dust, lake spray, and heavy seasonal pollen make pressure washing tempting — but the mix of surfaces on local cottages and condos means caution is essential. A professional crew knows how to adjust PSI, select the right nozzle, and protect vulnerable surfaces.

Final Thoughts

Pressure washing can make a huge difference to your home’s curb appeal — but only if it’s done safely. For Invermere homeowners, the trick is knowing which surfaces are safe to tackle and which require professional care. With the right tools and expertise, you’ll get spotless results without the risks.
