Gap Under the Garage Door — Columbus
Daylight, snow, water or salt slurry coming in under a closed door.
What it usually means in Columbus
Check the concrete before you buy another seal. Road salt plus repeated freeze-thaw spalls and pits the apron immediately outside the door, and once that threshold is no longer flat there is nothing for a bottom seal to seal against - which is why owners here replace the rubber twice and stay draughty. The other local cause is glacial-till clay under the slab moving with the moisture, leaving the floor out of flat. If the gap is in the middle rather than at an end, look down rather than at the door.
