Power Washing Strata Buildings: 7 Reasons to Set a Regular Schedule

Power washing doesn’t get much attention until someone brings it up at an AGM, usually right after a resident complains about the black streaks running down the parkade entrance or the algae creeping up the north wall. If you sit on a strata council, you already know the building’s exterior says a lot before anyone even steps inside. It’s one of the simplest ways to keep a strata property looking cared for, but most councils only think about it once a problem shows up. A regular power washing schedule does more than keep things looking tidy. It protects the building, keeps walkways safer, and can save your strata real money down the road.

Here’s what we’ll cover:

• What counts as power washing (and what doesn’t)
• Why strata councils are on the hook for this
• What happens when you skip it
• How often a strata building should schedule power washing
• What a proper power washing schedule actually covers
• Picking a contractor your council can trust

What Counts as Power Washing (And What Doesn’t)

People throw around “power washing,” “power scrubbing,” and “power sweeping” like they’re the same thing. They’re not. Power washing uses pressurized, and sometimes heated, water to blast dirt, algae, gum, and grime off hard surfaces like concrete, stucco, and pavers. Power scrubbing adds a rotating brush for stubborn stains, usually in parkades. Power sweeping is a dry method that clears loose debris before either of those happens.

For most strata buildings, a good exterior maintenance plan uses all three at different points in the year. But when councils talk about brightening up the entryway, the sidewalks, or the building’s siding, that’s almost always what they mean.

Why Strata Councils Are on the Hook for This

Under BC’s Strata Property Act, strata corporations are generally responsible for maintaining common property, and that includes the exterior of the building. The Province of BC’s guidance on repair duties is clear that councils need to maintain, repair, and renew assets like building envelopes, parkades, and landscaping, not just react when something breaks.

That’s not just a legal box to check. A depreciation report will eventually flag deferred exterior cleaning as deferred maintenance, and owners tend to notice a dirty building long before they read a depreciation report. Keeping a documented power washing schedule gives your council something concrete to point to when owners ask what’s being done with their strata fees.

We put together more general guidance for councils on this in our strata building cleaning and maintenance services page, if you want the fuller picture beyond just this one piece of it.

What Happens When You Skip It

Concrete, stucco, and siding all hold onto moisture, and moisture is what mold, mildew, and algae need to take hold. The EPA’s guide on mold and moisture is a good reminder that mold damages whatever it’s growing on, and the longer it sits, the worse that damage gets. On a strata building, that shows up as stained stucco, degraded sealant, and surfaces that age faster than they should.

There’s a safety angle too. Algae on a ramp or a shaded walkway gets slick fast, especially through a Vancouver winter. For a council, that’s not just a maintenance issue, it’s a liability issue. Regular power washing is part of basic commercial property maintenance, right alongside snow removal and lighting checks, because it directly affects how safe the property is to walk through.

How Often Should a Strata Building Schedule Power Washing?

There’s no single answer, since it depends on exposure, shade, and traffic. As a general rule, we tell strata councils:

• Full building exterior (siding, stucco, entryways): once or twice a year
• High-traffic walkways and entrances: quarterly
• Parkade ramps and drive aisles: quarterly to monthly, depending on the season
• Garbage and recycling areas: monthly, at minimum

Buildings in shaded spots, or anything close to trees, usually need it more often because moisture just doesn’t dry off the same way. If your building backs onto a forested area or gets a lot of rain runoff, lean toward the higher end of these ranges.

What a Proper Power Washing Schedule Actually Covers

A one-off power wash before the annual general meeting looks nice for a week and then fades. A real schedule covers the building systematically:

• Main entryways and lobby approach
• Sidewalks and common walkways
• Parkade ramps, entrances, and stairwells
• Garbage, recycling, and loading areas
• Exterior siding, stucco, and trim

One note for councils: balconies and patios are often limited common property, and responsibility for cleaning them can fall to individual owners depending on your bylaws. It’s worth confirming that before you assume those areas are covered under a common property contract.

Picking a Power Washing Contractor Your Council Can Trust

Not every pressure washer belongs on a strata building. High-pressure water on the wrong surface can strip sealant, force water behind siding, or damage landscaping. A council should be asking any prospective contractor about their experience specifically with strata and commercial properties, not just residential driveways.
