Markham is roughly a 40-minute run from our Mississauga shop — less if a technician is already in the area — so a truck is usually on site the same day.
Emergency board-up, security and make-safe first — permanent repair scheduled after.
Aluminum storefront framing, and which series an opening in Markham takes
Framing is bought by series, and three things separate one from the next: how deep the frame is, where the glass sits in that depth, and how the corners go together. None of it shows from the pavement; all of it sets the price.
The hardware in a storefront entrance, and what goes first
The glass and the framing almost never fail. What wears out on an entrance in Markham is the ironmongery holding the leaf up and pulling it shut, and that is what most storefront service calls turn out to be.
Why a storefront leaks, and it is almost never the glass
Aluminum framing is a drained system, not a sealed one. Water gets past the outer face, runs down an internal gutter behind the glazing pocket and leaves through weeps at the sill. When it shows up inside, one of those three stages has been interrupted — and new glass fixes none of them.
What a 25-year-old Markham storefront needs, and in what order
Most ground-floor elevations we are asked to price in Markham do not need replacing. The useful question at the survey is which three or four things are due now, and in what order.
Supplying a storefront in Markham: the price and the date
We install what we supply and we supply on its own — contractors in Markham who hang their own buy the package cut and prepped to the schedule. Four things move the number more than size does.

Storefronts for the work Markham buildings do
The sectors that dominate Markham — technology campuses, corporate offices, light manufacturing — each put a different kind of traffic through the front of the building.
Technology campuses
A business-park elevation is the whole ground floor — entrance doors, a transom above and a window band running either side, thermally broken where the lobby is heated. Tenant turnover is what brings us back: a new sign, a new cylinder, and often a new entrance in an existing frame.
Light manufacturing
A plant’s storefront is the front office bolted onto a steel building, and the two halves age differently. The framing is usually sound; what lets water in is the joint where aluminum meets precast. The elevation can be rebuilt without touching the production wall behind it.
Retail plazas
This is the opening the system was drawn for: a narrow-stile leaf, the widest glass the opening allows, and a closer sized to the door traffic rather than to the frame. The work happens after close, bay by bay and hoarded overnight, so the store trades in the morning.
Schools & institutions
School and college glazing is a summer job — the elevation comes out and goes back inside one shutdown, because it cannot be phased around a timetable. Wider stiles than a shop uses, because these leaves carry exit devices and take the traffic of a bell.
Condos & property management
A managed building’s ground-floor elevation is the line on the reserve-fund study nobody wants to open. Usually it does not all need replacing: fogged units, a dropped leaf and a failed perimeter joint account for most of it, quoted separately so a board can see what is repair and what is capital.
Hotels & hospitality
A restaurant front is the marketing, so the framing finish matters as much as the glass — dark anodized or powder-coated aluminum, and a leaf that takes a whole evening of traffic. Installation goes in on the nights the kitchen is closed, and that sequence is quoted with the product rather than after it.

Tell us the elevation — its rough width and height, whether the framing is staying, and what your trading hours are, because the sequence is most of the price. A photo from across the street is enough to start. Working from drawings? Send the glazing and door schedules and we quote to them.
Common questions about storefront doors & glass
How much does an aluminum storefront cost?
It depends on the glazed area, the glass make-up, whether the framing is thermally broken, how many doors are in it and what hardware they carry — a single door in existing framing and a rebuilt elevation are not the same order of number, so a "from" price would mislead. Two things move it more than buyers expect: a thermally broken frame, and working after hours to keep the store trading. We measure and send a firm, itemised quote at no charge.
What type of glass is used in a storefront?
Exterior storefronts are almost always glazed with a 1″ sealed insulating unit — two lites around an argon or air cavity — with a low-E coating on one surface and the outer lite tempered where the Ontario Building Code requires safety glazing. Glass in and beside a door is always a safety glazing location. Interior storefront and partition glazing is usually monolithic 6 mm tempered, and laminated glass replaces tempered where security, sound or fragment retention matters.
Is an aluminum storefront better than hollow metal?
They answer different questions. Aluminum carries large areas of glass on slim sightlines, never rusts, takes any anodized or powder-coat finish and is what a customer-facing entrance should be. Hollow metal is stronger, less expensive per opening and the only one of the two that can carry a fire label — which is why the front door is aluminum and the stairwell, the mechanical room and the back exit are steel. Most buildings we work on have both, and we supply both.
