Short answer: most commercial glass storefronts in Toronto and the GTA cost roughly $75 to $150 per square foot installed in 2026. A small single-unit plaza storefront with one entrance door often lands in the low-to-mid five figures; a large, fully glazed corner unit with double doors and insulated glass can run considerably higher. Below is what actually moves the number — and how to budget so your opening date isn’t derailed by surprises.
What’s included in a storefront price
A storefront quote isn’t just glass. A complete system typically includes the aluminum framing (mullions, transoms and sills), the glass itself, one or more entrance doors with closers and hardware, sealants and flashing, removal of the old storefront if there is one, and installation. Make sure any quote you compare lists the same components — a cheap number that leaves out the doors or the demolition isn’t really cheaper.
The six factors that drive storefront cost
1. Size and layout
Storefronts are priced largely by area, but layout matters too. A simple run of equal-width panels is more economical than a façade with many small lites, curved sections, or a corner that wraps two elevations. Taller storefronts may need heavier mullions or reinforcement to handle wind load.
2. Framing system
Basic aluminum storefront framing is the budget baseline. Thermally broken framing — which separates the inside and outside of the frame to stop heat and cold conducting through — costs more but reduces condensation and keeps the front of the store comfortable in winter. Custom powder-coat colours to match a brand or a plaza specification add a little over standard clear anodized or black.
3. Glass type
Glass is where the biggest choices sit. Tempered safety glass is the standard minimum. Laminated glass adds a tough interlayer that holds the glass together if it’s struck — a strong deterrent to smash-and-grab break-ins. Insulated Low-E units (double-glazed with a heat-reflective coating) cost more again but cut solar heat gain, glare and drafts — valuable on south- and west-facing façades and for restaurants and clinics where comfort matters. Tinted, frosted or film-treated glass adds privacy where needed.
4. Doors and hardware
Each commercial entrance door is a significant line item. Single doors cost less than pairs; heavy-duty closers, cylinder locks and push/pull hardware are standard; and panic hardware may be required depending on your occupancy and the number of people the space holds. If you plan to add automatic door operators or access control later, tell your installer now so the frame and door are prepared for it.
5. Removal, site conditions and access
Replacing an old storefront means careful removal and disposal, and older openings often hide out-of-square masonry or deteriorated sills that need attention. Downtown sites with limited loading access, or units that must stay open during work, can add labour. A proper site measure surfaces these issues before you sign — which is exactly why we quote only after visiting.
6. Permits and drawings
A new or altered storefront usually needs a building permit, and the application needs framing details, glass specifications and sometimes structural verification. Budget for drawings and permit time in your schedule. At Skyline Glass we prepare the technical details as part of the project so the paperwork doesn’t become the bottleneck.
Typical storefront budgets
- Glass replacement in an existing frame: the most economical option — priced per lite, depending on size and glass type.
- Small plaza unit, single door, tempered glass: a straightforward project at the lower end of the per-square-foot range.
- Restaurant or clinic with insulated Low-E glass and double doors: mid-to-upper range, reflecting the glazing and door package.
- Large corner unit, laminated security glass, custom colour: upper range, driven by area, glass and finish.
These are planning ranges to help you budget — your real number comes from a fixed quote after a site measure.
Where it’s worth spending — and where you can save
Worth it: laminated glass if your area has break-in risk (one avoided incident pays for it); insulated Low-E glass on sunny façades (lower cooling bills, less fading of displays, happier staff); and quality door closers and hardware, because the entrance takes more abuse than any other part of the building. Where to save: standard frame colours instead of custom, a simpler panel layout, and reusing a sound existing frame by replacing only the glass when the framing is still in good condition.
Storefront glass and your energy bills
A storefront is often the largest area of glass in a commercial unit, so it has an outsized effect on heating and cooling. Older single-glazed storefronts lose heat in winter and let in heavy solar gain in summer, which means cold drafts at the entrance, overworked HVAC and displays that fade in the sun. Upgrading to thermally broken framing with insulated Low-E glass keeps the front of the store comfortable year-round and reduces energy use — a saving that continues for the life of the lease. For restaurants with front-window seating and clinics with waiting areas near the glass, the comfort benefit alone is often worth the upgrade.
Storefront vs. curtain wall: which do you need?
The terms are sometimes used interchangeably, but they describe different systems. A storefront system is designed for ground-floor openings — typically one storey high — where the framing sits between the floor and the structure above. A curtain wall is a different, heavier system that hangs off the building structure and can run up several storeys, as seen on office towers. Almost every retail, restaurant and clinic unit in a GTA plaza or main street uses a storefront system, which is simpler and more economical to install. If your project is a multi-storey façade, that’s a different conversation to have early with your designer.
Looking after your storefront
Storefronts are low-maintenance, but a little care keeps them performing. Clean the glass and frames regularly to stop dirt and road salt etching the finish; check door closers and pivots every few months, since an entrance that slams or drags wears out quickly; and inspect perimeter sealant annually, especially on sun- and weather-facing elevations. Catching a failed seal or a sagging door early is far cheaper than replacing a damaged frame or a cracked lite later.
How long does a storefront take?
After the site measure and drawing approval, fabrication typically takes 3–6 weeks depending on glass and framing. Installation of a single-unit storefront usually takes one to two days. If you’re working toward an opening date, book the measure as soon as your lease is signed so permits and fabrication run in parallel.
Questions to ask any storefront contractor
- Is the quote fixed, and does it include doors, hardware, removal and disposal?
- What glass is specified — tempered, laminated or insulated Low-E?
- Will you prepare the permit details, and who verifies structure?
- Will you work to my landlord’s tenant criteria?
- Who installs — your own crew or subcontractors? What is the warranty?
