If you manage a commercial building, strip mall, apartment complex, or industrial property anywhere in Metro Vancouver, you already know the coastal climate doesn’t do your exterior any favours. Rain, moss, algae, and diesel soot build up faster here than almost anywhere else in Canada — and unlike a homeowner who can clean whenever it’s convenient, a property manager has tenants, lease terms, insurance, and liability to think about. So how often does a commercial property actually need to be pressure washed? The honest answer is “it depends which surface you’re asking about.” This guide breaks down a realistic schedule for every part of a commercial site.
Why Commercial Exterior Cleaning Isn’t the Same as Residential
A homeowner who skips a year of house washing ends up with green siding — not ideal, but not a liability. A commercial property is different. Slick moss on a sidewalk or entrance ramp is a slip-and-fall claim waiting to happen. Grimy storefront glass and a moss-streaked facade tell every customer walking in that the business (or the building manager) isn’t paying attention. And a lot of commercial leases and strata bylaws actually specify minimum standards for exterior upkeep. That’s why commercial pressure washing tends to run on a real maintenance schedule instead of “whenever it starts to look bad.”
How Often Should You Book Commercial Pressure Washing?
Building exteriors and siding
Most low-rise commercial buildings, retail plazas, and industrial units in Metro Vancouver need a full exterior wash once or twice a year. North-facing walls and anything shaded by trees or neighbouring buildings collect algae faster and may need a second pass. Buildings right along the coast or near a creek see more moisture in the air and usually land on the higher end of that range.

Parkades and underground parking
Underground and covered parkades don’t get rained on, but they still need attention — tire residue, oil drips, salt tracked in during winter, and general grime build up on the concrete floor and get ground into it by traffic. Most strata and commercial parkades we service get washed once or twice a year, with high-traffic visitor stalls and entrance ramps sometimes done more often since they’re the first thing a visitor sees.
Sidewalks, entrances, and walkways
These take the most abuse and need the most frequent attention, especially through our wet fall and winter months when moss and algae get a head start on any concrete that doesn’t dry out between rains. A quarterly cleaning for main entrances and heavily walked paths is a reasonable baseline for liability reasons alone — a clean, dry-looking walkway is a lot less likely to cause a fall than one with a green film on it.
Asphalt lots and loading areas
Asphalt doesn’t grow moss the way concrete does, but oil stains, gum, and general grime accumulate in loading zones and parking stalls. Property managers looking into asphalt cleaners for a parking lot are usually dealing with oil staining near loading docks or garbage areas — an annual cleaning of those specific high-traffic spots, rather than the whole lot, is usually the most cost-effective approach.
What a Full Commercial Exterior Cleaning Service Should Include
- Building walls and siding (soft washing, not just a blast of pressure)
- Storefront and window glass
- Parkade floors and ramps
- Sidewalks, entrances, and stairwells
- Dumpster enclosures and loading areas
- Graffiti removal on painted or unpainted surfaces
A good commercial provider will scope this out with you first rather than quoting a flat number sight unseen — a single-storey retail unit and a six-storey mixed-use building need very different equipment and time on site. If your maintenance plan also covers glass, our window cleaning service is usually bundled into the same visit to save you a second trip charge.
Graffiti: The One Job That Can’t Wait for a Schedule
Every other item on this list can sit on a calendar. Graffiti can’t — the longer a tag sits on a storefront or wall, the more likely it is to attract more of it, and most municipalities and strata corporations expect it removed within days, not months.
We treat graffiti calls separately from a regular maintenance schedule — they get prioritized ahead of routine work because the cost of leaving it up (to the property’s image and to attracting more of it) climbs every day it’s visible.
Commercial vs. Residential Pressure Washing: What Actually Changes
Beyond the surfaces themselves, commercial jobs differ from a house wash in a few practical ways. The equipment runs bigger volumes of water over larger areas, so jobs are scheduled in blocks rather than squeezed between other stops. Work usually happens early morning, evening, or weekends to stay out of the way of tenants, staff, and customers. And because commercial clients need proof of insurance, scheduled invoicing, and sometimes a signed maintenance agreement for their records, the paperwork side of a commercial account looks more like a service contract than a one-off booking. If your property also needs its parking lot or entrance concrete addressed separately from the building itself, our driveway and concrete cleaning service covers that on its own or alongside a full exterior visit.
FAQ
How much does commercial pressure washing cost?
It depends on square footage, how many surface types are involved (walls, parkade, sidewalks, glass), and how often you book. Because every commercial site is different, we scope each one individually rather than quoting a flat rate — request a quote and we’ll walk the property with you.
Do you work around business hours?
Yes. Most commercial accounts are scheduled early morning, evening, or on weekends specifically so we’re not in the way of customers, tenants, or deliveries.
Can you handle graffiti removal on short notice?
Yes — graffiti calls get prioritized ahead of routine scheduled work because of how quickly it needs to come down.
Do I need to sign a long-term maintenance contract?
No. We can do a single visit or set up a recurring schedule (quarterly, semi-annual, or annual depending on the surface), whichever fits how your property is managed.
