Daylight or drafts around the garage door
Urgency

Honest verdict: you can likely DIY this$0–$400Typical repair cost
Likely causes, most common first
- Bottom seal flattened or torn (they're consumables)
- Side/top weatherstop shrunken away from the door
- Slab settled unevenly leaving a corner gap the seal can't span
Do this right now
- Close the door with the lights on inside: mark every daylight line
- Bottom seals slide out of a track — carry the old one to match the profile; larger sizes exist for uneven slabs
DIY or call a pro?
Seals are honest DIY. Call for slab-gap corners needing a threshold ramp, rotted jamb trim behind the weatherstop, or if the door itself is racked — and never touch the springs; that's a specialty trade for good reasons.
