Broken glass in St. Catharines: we dispatch 24/7.
St. Catharines is roughly a 80-minute run from our Mississauga shop — less if a technician is already in the area. Planned work, measures and maintenance travel there without difficulty; on a middle-of-the-night emergency we will tell you the drive time on the phone, and what to do to make the opening safe until we arrive.
Emergency board-up, security and make-safe first — permanent repair scheduled after.
The glass that goes back into a commercial opening in St. Catharines
Commercial glazing is a small number of make-ups, not one product, and most openings combine two or three of them. Which one goes back into a broken opening in St. Catharines is settled by three things: where the Ontario Building Code says safety glazing is required, how deep the glazing pocket is in the frame that is staying, and what broke the last one. Safety glazing is certified to CAN/CGSB-12.1, and in or beside a door it is not optional.
Broken glass repair, or replacing the window or door?
Most broken commercial glass in St. Catharines is a glass job. The frame is straight, the anchoring is sound, the hardware still works, and only the lite has failed — so the opening is reglazed and nothing else changes. Replacement earns its place when the thing that failed is the frame: bent or corroded aluminum, a dead thermal break, or a glazing pocket too shallow for the unit the opening now needs. On a door there is a third answer that rarely gets offered — the leaf and frame stay, and the glass and the hardware around it are rebuilt in place.

Glass and windows for the work St. Catharines buildings do
The sectors that dominate St. Catharines — healthcare and social assistance, retail trade, manufacturing — each break their glass in a different way.
Healthcare and social assistance
A taped-up lite in a waiting room is the thing patients photograph. Clinic and hospital glass goes back as the safety glazing it came out as, in hours that do not collide with the clinic list, and is made safe immediately where it cannot.
Retail trade
Shopfronts take the damage: forced entry overnight, a display bay hit from the pavement, a door lite starred by a cart. We board the opening the same night, measure while we are there, and glaze early enough that you trade the next morning.
Manufacturing
Plant glass fails from vibration, impact and heat as often as from forced entry — a cracked vision lite in a shop door, a stressed pane beside a bay. We match the make-up to what broke it rather than putting the same lite back.
Accommodation and food services
Vision panels and interior glazing in a food or pharma plant have to go back in cleanable and properly sealed, and the reglaze has to fit a sanitation window. We work the shutdown rather than asking for one.
Educational services
Schools and campuses run assemblies built decades apart, including wired and early safety glazing that can no longer simply be matched like for like. We replace to what the code asks for now, and we work the breaks and the evenings.
General contractors & new builds
On a live site the glass usually breaks after it is in: another trade catches a lite, or a unit arrives damaged. Replacing it against the glazing schedule without holding up the handover is the whole job.
Broken glass in St. Catharines: board-up first, then the reglaze
If the opening is open to the street, call 800-522-6825 rather than filling this in — the line is answered 24 hours and the board-up comes first. For a cracked lite, a fogged unit or a quote to reglaze, tell us the opening and roughly how big it is.
Common questions about commercial glass & window repair
What can I use to temporarily fix a broken window?
Tape holds fragments together for photographs and nothing else — it does not make an opening secure or weathertight, and it leaves loose glass in a frame above a pavement. The real answer is a board-up: the remaining glass is cleared out, and plywood is cut and fixed into the frame so the building locks tonight. Ours is done with the glazing stops so the frame is not damaged, and the plywood comes out the day the new unit goes in.
Is a broken window an emergency?
Treat it as one if the opening is no longer secure, no longer weathertight, or has glass left in the frame that can still fall. A cracked pane that is intact and above head height can usually wait for a scheduled visit; a shattered storefront at street level cannot, and neither can a fire exit whose glass is gone. The test we use on the phone is simple: can the building be locked and left tonight? If not, it is an emergency and we board it up.
Do you repair glass you did not install?
Yes, and it is most of what we do. We service commercial storefronts, windows, entrance doors and partitions regardless of who supplied them, including framing systems no longer manufactured — those jobs start with identifying the frame and the glazing method before anything is ordered. Because we do the framing side of the trade as well as the glass, when the answer is that the frame has to go we can quote that instead of handing you to another contractor.
