What Is Storefront Glass Replacement?
Storefront glass replacement means taking out a broken, cracked or failed panel in a commercial frontage and setting a new, code-compliant lite into the existing frame. On most Toronto retail strips that frame is extruded aluminum storefront framing with a thermal break mullion, glazing beads and rubber gaskets. The glass itself is usually 6mm or 10mm CSA A440 tempered, sometimes SentryGlas laminated, and in a few openings Pyrostop fire-rated glazing where the storefront forms part of an OBC Part 3 fire separation.
The work is different from a house window in three ways. The panels are bigger and heavier, so we use suction lifters, a glass dolly and at least two installers. The glass is almost always safety glass, so it cannot be cut on site and has to be made to size by a fabricator. And the store is losing money while the opening is boarded, so the speed of the permanent install matters as much as the quality.
Types of Storefront Glass We Install
Most frontages we see on Queen West, King West, Ossington and the Danforth use one of four glass types:
- CSA A440 tempered glass, 6-10mm. The standard for storefronts and entrance sidelites. It is about four times stronger than annealed glass and breaks into small cubes instead of shards.
- SentryGlas laminated glass. Two lites bonded with a stiff ionoplast interlayer. When it breaks it stays in the frame, so it slows down a break-in and keeps the store weathertight until we replace it.
- Pyrostop fire-rated glass. Required where glazing forms part of a fire separation under OBC Part 3, often next to exit corridors in mixed-use buildings.
- Low-E coated insulated glass units. Used in heated vestibules and newer storefront systems where energy performance matters. We match the coating with Guardian ClimaGuard, Pilkington OptiTherm or Vitro Solarban 70XL.
When Do You Need Storefront Glass Replaced?
Break-ins are the obvious reason, and they are most of our late-night calls. But a lot of storefront replacements are planned. Here are the situations where replacement, rather than repair, is the right call:
- The panel is shattered or cracked through. Tempered glass cannot be repaired once it has a running crack. It has to come out.
- A thermal stress crack has started from the edge. Common on dark-tinted or partially shaded glass in early spring, when the sun hits a cold panel.
- The landlord or insurer wants laminated glass after a second break-in. Many Yorkville and Queen West leases now require it.
- An inspection flagged annealed glass in a safety zone. Older frontages sometimes still have plain plate glass where code now needs tempered or laminated.
- You are renovating the store. New signage, a new entrance or a change of use under OBC Part 3 can trigger a glass upgrade.
If the damage is a small edge chip, a leaking gasket or a loose glazing stop, you may only need storefront glass repair, which costs much less.
What Drives the Cost of a Storefront Panel?
The published range is $1,200-$5,500 per panel. Where your job lands depends on a few things you can usually check yourself before you call:
| Factor | Lower cost | Higher cost |
|---|---|---|
| Panel size | Under 24 sq ft | Over 48 sq ft |
| Thickness | 6mm tempered | 10mm tempered or laminated |
| Glass type | Standard clear | SentryGlas, low-iron or Pyrostop |
| Access | Ground floor, open sidewalk | Upper floor, lane permit needed |
| Timing | Scheduled install | Same-week custom fabrication |
Sizes are measured as the visible glass, so a 6 ft by 8 ft display window is a 48 sq ft panel. When we quote, every line is separate: glass, labour, sealant, setting blocks and gaskets, any permit and the board-up.
Repair, Replace or Upgrade?
For a shattered or cracked tempered panel, replacement is the only option. The real decision is what to replace it with. In our experience, a store that has been broken into once is likely to be targeted again within a couple of years, so laminated glass on the most exposed panels is often money well spent. For a store that has never had a break-in, matching the existing tempered glass keeps cost down and the frontage looking uniform.
If you are not sure, the crew will show you the options on site and price both on the same quote. You choose, and the adjuster gets the itemised version either way.
How We Protect Your Store During the Swap
Glass is only part of the job. We lay floor protection inside the store, set up a pedestrian barrier on the sidewalk, and keep the old panel in place or boarded until the new one is ready to set. When the new lite goes in, it sits on fresh setting blocks so the weight is carried at the right points, the gaskets are seated all the way round, and the perimeter is sealed with Dow Corning 795. We clean the glass, sweep the sidewalk, and leave with the broken lite and the plywood.
