North Vancouver Garage Door Guide
Why Daylight Shows Around a Closed Garage Door
A thin, even line at a flexible seal is different from a widening triangular gap or one corner that does not meet the floor. Gaps affect drafts, water, pests, energy use, and security.

Quick answer
Daylight around a closed garage door usually indicates a worn perimeter seal, uneven floor, door misalignment, incorrect track spacing, damaged panel, or insufficient contact at the top or sides. The location and shape of the light gap identify the likely cause.
What to understand first
Bottom gaps often follow floor shape
Older slabs can settle or wear unevenly, leaving low spots.
Side gaps can come from seal wear or track position
The door may sit too far from the jamb or the vinyl stop may have hardened.
Top gaps may reflect header seal or door position
A bowed top section or opener-arm geometry can change contact.
Triangular gaps suggest alignment or structural issues
A crooked door, damaged panel, cable problem, or shifted track needs assessment.
Safe checks and next steps
- Inspect the gap from inside during daylight. Photograph the pattern with the door fully closed.
- Check flexible seals. Look for cracks, flattening, shrinkage, and missing fasteners.
- Confirm the door is level. Compare bottom corners without touching cables or brackets.
- Watch one closing cycle. Note whether the door reaches the floor evenly.
- Avoid forcing excess closure. Do not increase opener force to crush the seal or compensate for alignment.
Do not loosen, wind, cut, or reposition garage door springs, cables, drums, bottom brackets, or loaded track hardware. Stop if the door is heavy, crooked, partly off track, or moving unpredictably.
North Vancouver conditions to consider
Rain and wind make small gaps more noticeable in North Vancouver. Water staining and debris trails can show where air and moisture enter.
For adjacent guidance, review choosing a seal strategy and water entry at the threshold.
When professional service makes sense
Call for service when gaps are uneven, the door is crooked, panels are bent, tracks need adjustment, or replacement seals do not contact correctly.

Frequently asked questions
Can I add thicker weather stripping?
Sometimes, but oversized seals can bind, drag, or hide alignment problems.
Why is there light only at one bottom corner?
The floor may be low, the seal damaged, or the door may not be level.
Will a new door solve an uneven floor gap?
Not by itself. The floor shape may still require a suitable seal or threshold strategy.
