Removing Paint from Commercial Windows in Vancouver: What Works on Glass, Frames and Brick

Why Sandblasting and Window Glass Don't Mix

Abrasive blasting cuts glass. Full stop. That's how frosted and etched glass is made in the first place, so pointing a blast nozzle at a painted window trades a paint problem for a cloudy pane you'll be replacing. Softer media like baking soda or crushed walnut shell are gentler, but they can still haze glass, and they're riskier on panes with tint film or low-e coatings.

So on a storefront, the glass gets masked and the paint on it comes off another way. Flat glass usually responds to a sharp razor scraper held low on wet glass, or to a stripper made for use on glass, tested first in a corner. Glass makers do warn that scraping some tempered panes can leave fine scratches, so that test patch matters. Most of the sandblasting Vancouver storefronts actually need happens around the glass rather than on it: the frames, the lintel above and the brick or stone on either side.

Frames, Mullions and Lintels: Where Blasting Earns Its Place

Steel window frames and lintels on older commercial blocks in Gastown, Chinatown and along Main Street often carry decades of paint, with rust working underneath. Scraping that by hand rarely gets to sound metal. Blasting does, and it leaves a clean surface with enough profile for primer to grip. Bare steel then gets primed the same day, because freshly blasted metal starts to rust quickly in damp Vancouver air.

Aluminum storefront frames are a different call. An anodized finish is part of the metal surface, and abrasive blasting removes it along with the paint. Powder-coated frames can be stripped with gentle media and recoated, but at that point it's worth asking the frame supplier whether refinishing or replacing makes more sense. Before you hire anyone for paint removal Vancouver storefront work, ask what they'd do with your specific frame material. A clear answer tells you a lot.

Brick, Stone and Graffiti Around the Windows

Masonry around storefront windows picks up paint from old signage, mismatched touch-ups and graffiti. Brick is softer than steel, so the work runs at lower pressure with finer media, and the goal is to lift the paint without rounding the brick faces or eating into the mortar joints.

On a busy sidewalk, dust is the bigger issue. Dry blasting next to an open shop door or a café patio is a hard sell, which is why most of this work uses a wet setup. Water knocks the dust down so it falls close to the wall instead of drifting into the store. Our dustless blasting Vancouver setups are built for exactly this kind of tight, occupied frontage.

One more check before stripping any facade: older buildings may be on the City of Vancouver heritage register, and work on a listed exterior can need approval first. It's a short phone call that can save a stop-work order.

Lead Paint on Older Storefronts

Plenty of Vancouver's commercial stock was painted long before lead was phased out of most paints, and those old layers are often still there under the newer ones. Blasting lead paint without controls puts lead dust on the sidewalk, inside the store and on the crew. WorkSafeBC sets the rules for lead exposure on job sites, and they cover testing, containment, protective equipment and how the waste leaves the site.

So a paint sample gets tested before the job is priced if the building is older or the paint history is unknown. If lead turns up, containment gets heavier and disposal gets more involved, and the quote reflects it. Any contractor who wants to start blasting an old storefront without asking about lead is skipping a step that protects you as much as them.

What Storefront Paint Removal Costs

Most residential jobs run $300 to $800 depending on surface size and condition. Commercial storefronts are priced by scope instead, because the blasting itself is often the smaller part of the job. Masking glass properly takes time. So does access, whether that's a ladder, scaffolding or a lift for second-storey windows. Scheduling early mornings or weekends so the business stays open adds hours, and lead testing or heavier containment adds more.

The quickest way to an accurate number is a handful of photos: the full frontage, a close-up of the frames and a shot of the worst paint. With those, a contractor can tell you which parts blasting handles, which parts need hand work, and roughly where the job lands before anyone visits. Ask for a written estimate that lists the surfaces, the method for each and the cleanup plan.
