QUICK ANSWER
If water, leaves, or light get under your closed door, the bottom seal is worn. Replacing it is a quick job that keeps the garage cleaner and drier.
The bottom seal is the rubber strip along the bottom edge of the door. It dries and cracks in the sun and gets torn by the floor over time.

Why it matters
A good seal keeps out rain, dust, and bugs, and it protects the bottom of the door from rust. For the sides and top, see weather seal replacement.

What can cause the problem?
A worn sealing strip
The bottom strip can crack, flatten, or pull out of its retainer. A matching replacement depends on the profile and door width.
An uneven bottom edge
A bent section, damaged retainer, or sloping floor can leave a gap that replacing rubber alone will not resolve.

Can a thicker seal fix any gap?
No. A larger profile may not suit the retainer or solve uneven travel or slab issues. The source of the gap should be established before choosing a replacement.
Will this also replace the side seals?
Not unless that work is included in the estimate. Bottom and perimeter seals serve different edges of the opening. Point out every area of concern when discussing the visit.
