A gap under the garage door in Columbia usually means a worn bottom seal or an uneven door. Both are quick, affordable fixes.

In Columbia, the weather is often part of the story behind a gap under the garage door. Months of freezing winters mean cold snaps brittle springs and road salt corrodes hardware across Howard County — exactly the kind of wear a local tech knows to check first.
