Burlington's lakefront location means humidity swells wood frames in summer and Lake Ontario wind chill drives freeze-thaw movement in winter. Older Aldershot homes and newer Millcroft builds both see seasonal latch failures from this annual cycle.
The result is a door that closes cleanly in September but requires extra force — or won't latch at all — by December. This is almost always a frame alignment issue, not a lock or handle problem.
Common Signs of Winter Frame Shift
- Latch doesn't reach the strike — door springs back open
- Visible gap at the top corner of the door
- Door drags or sticks when trying to close
- Lock requires extra force to engage
- Cold air infiltration at the frame edge
Repair vs. Replacement
Most Burlington winter door latch failures are fixable without replacing the door. Strike plate relocation and hinge adjustment address the most common patterns in a single visit. We assess the frame and slab condition before recommending anything and explain what we find.
Full replacement is only necessary when the frame has rotted significantly or the slab has warped beyond adjustment. We tell you honestly which situation you're in.
Prevention Before Next Winter
- Check strike plate alignment in October while the door is still easy
- Tighten all hinge screws — add 3-inch screws into structural framing if the jamb is soft
- Replace flattened weatherstripping before cold arrives
- Lubricate the latch bolt with dry graphite — not WD-40
Common questions
Quick answers to what homeowners and property managers ask most about this problem.
Why does my Burlington door stop latching every winter?
Seasonal frame movement misaligns the latch and strike by a few millimetres. We can usually fix this in a single visit by relocating the strike to where the latch now lands.
Is it worth repairing or should I replace the door?
If the slab and frame are structurally sound, repair is almost always the right path. We assess both on site before recommending replacement.
