Mortise Lock Repair in Toronto: local context
Toronto's freeze-thaw winters swell and shrink door frames, and older buildings often have frames that have moved out of square. A repair that ignores the frame will not last, so we assess the whole opening. Typical callers: heritage homeowners, apartment buildings and older storefronts.
What we will and won't do
Fire-rated doors keep their rating: we use listed parts and never drill or cut a rated door beyond its listing.
Frequently asked questions
Can you keep the original knobs?
Often yes. The trim can stay while the working parts are renewed.
Can a mortise lock be repaired or should it be replaced?
Many can be repaired. If a spare part cannot be sourced, a modern mortise body in the same pocket is the usual answer.
Will a new lock fit the old door?
Modern mortise bodies are made to fit standard pockets, so a replacement is often possible without cutting the door.
