When a commercial door won’t latch, won’t lock, or drags every time someone walks through it, that’s not a maintenance item you can put off — it’s a security and liability problem sitting at your front entrance. Treco Locksmith & Security provides fast, fully mobile commercial door repair across Burlington, Hamilton, Oakville, Stoney Creek, Milton and the wider Halton region, so a door that’s failing today gets handled today rather than left open overnight.
We’ve been a mobile operation since 2018, which for a commercial customer means one simple thing: we come to you. Whether it’s a storefront on a plaza, an office suite or an industrial service entrance, we arrive with the parts and tools to diagnose the door and, in most cases, repair it on the same visit. With a 5.0 rating across 204 Google reviews, business owners and property managers across the region trust us to get a door working and secure — not to upsell a replacement that isn’t needed.
Storefront, aluminium and steel commercial doors
Commercial doors take abuse that residential doors never see. High traffic, heavy leaves, weather and the occasional forced-entry attempt all wear an opening down over time. We repair both major types of commercial door:
- Aluminium storefront systems — the glass-and-aluminium doors common on retail plazas and offices throughout Burlington and Hamilton. We handle pivots, bottom rails, locks, closers, weatherstripping and the alignment issues that come with daily use.
- Hollow-metal and steel commercial doors and frames — the heavier service and industrial doors on warehouses, back entrances and equipment rooms. If a steel door or frame is too far gone to restore, we’ll tell you and point you to a proper commercial steel doors & frames replacement.
Door closer repair and replacement
A failing door closer is one of the most common — and most underestimated — commercial door problems. When a closer stops pulling the door fully shut, the latch never engages, which means the lock can’t secure the opening at all. That’s a real security gap hiding behind a door that looks closed.
It’s also an accessibility and safety issue. On accessible and fire-rated openings, the door has to close and latch reliably on its own; a closer that slams or fails to close defeats that. We service the commercial closers you’ll find on most local buildings — LCN, Norton and dormakaba among them — adjusting closing and latching speed, replacing worn or leaking units, and getting the door back to closing the way it should. For powered entrances and accessibility upgrades, ask us about automatic door operators.
Alignment, sagging and dragging doors
A door that drags on the floor, sticks in the frame or won’t latch is almost always out of alignment. Worn hinges, loose screws, a sagging frame or a strike that no longer lines up will all throw a heavy commercial door off true. We diagnose the actual cause rather than forcing the door shut and hoping.
Often the fix is re-aligning the door and replacing worn pivots. On high-traffic openings where ordinary butt hinges keep failing, a continuous (piano) hinge spreads the load across the entire height of the door, so it stops sagging and stays aligned far longer. We’ll recommend the hinge solution that matches how hard the door actually gets used.
Latches, strikes, locks and hardware
If the latch doesn’t catch the strike, the door isn’t secure — full stop. We repair and adjust latches, strike plates and mortise hardware so the door locks cleanly every time, and we address the worn locks and cylinders that leave a commercial door rattling loose. Where hardware is failing, we’ll match grade to use: ANSI/BHMA grading exists precisely so commercial openings get hardware rated for commercial traffic, and we fit accordingly rather than dropping in a residential-grade part that won’t last.
Weatherstripping, thresholds, glass and frames
Commercial doors leak air, water and energy when the seals go. We replace weatherstripping and thresholds to reseal the opening, and we repair the aluminium frame issues — bent rails, loose stiles, failed glazing — that come with years of use. A properly sealed, square door doesn’t just save on heating and cooling; it latches and locks the way it’s supposed to.
Break-in repair, re-securing and panic hardware
After a forced entry, the priority is getting you locked up again the same day. We repair the damaged door, frame, strike and hardware and re-secure the opening on the spot, re-keying or replacing any compromised lock or cylinder. If the door or frame can’t be restored to a secure standard, we’ll secure the opening and quote the replacement so you’re never left exposed.
We also service panic (exit) devices and exit hardware, adjusting them so they latch and release correctly and flagging units that need replacement. Reliable exit hardware is both an egress-safety and a security requirement — and on fire-rated openings it has to latch properly to do its job. See our dedicated panic & exit devices page for more.
