Lock Repairs, Installations, Rekeying & Commercial Door Hardware
CSI Montreal INC. services commercial buildings, storefronts, offices, and multi-unit properties across Greater Montreal, Ottawa, Cornwall, Trois-Rivières, and Quebec City. We also handle commercial doors, frames, and interior renovations.
Practical Lock & Door Hardware Solutions
We work with property managers, business owners, and facility teams to repair worn locks, restore key control, and keep entry and exit doors operating properly.
Repairing jammed cylinders, worn mortise bodies, misaligned latches, and sagging doors before they lock out staff or tenants.
Supplying and fitting commercial-grade cylindrical levers, mortise locksets, deadbolts, and aluminum storefront locks for interior and exterior doors.
Changing lock pin combinations when tenants move out or staff changes occur, and setting up master key hierarchies for multi-door buildings.
Installing and adjusting hydraulic door closers, panic exit bars, continuous hinges, electric strikes, and keypad locks on high-traffic doors.
Commercial Doors, Frames & Interior Renovations
When a door problem goes beyond the lock—such as rusted steel frames, damaged wood doors, or a suite layout change—our renovation crew handles the carpentry and interior work directly.
- Hollow metal and solid-core wood door and frame replacement
- Interior framing, drywall partitions, and acoustic ceilings
