The bottom seal (also called the door sweep) is the rubber strip running across the bottom of your garage door. It creates an airtight barrier against weather, water, insects, and dust. Austin's extreme heat also makes this seal critical for keeping your garage cooler. When it cracks, tears, or wears away, all of those benefits disappear — and replacement is one of the most affordable garage door services available.
Common Causes
How We Fix It
Bottom seal replacement takes 20–45 minutes. We measure your door width, cut the correct length of seal (T-slot, bead, or nail-on type depending on your door), and install it with a tight fit against your specific floor surface.
Frequently Asked Questions
How do I know if I need a new bottom seal?
Hold a light inside the garage at night and look for light visible under the door from outside, or do the reverse. Also look for water lines, bug trails, or dust accumulation near the bottom corners after rain or wind.
What type of bottom seal do I need?
Depends on your door. Most residential doors use a T-slot style where the rubber slides into a retainer track at the bottom of the door. Older doors may use nail-on seals. We bring all types and measure before cutting.
How much does bottom seal replacement cost?
Most bottom seal replacements run $65–$125 depending on door width and seal type. We quote before we start.
Does a new bottom seal help with energy efficiency?
Significantly. Especially in Austin where summer temperatures can hit 100°F+. A tight seal prevents hot air infiltration and keeps your garage (and any adjacent rooms) cooler.
Will a new seal work on an uneven floor?
We select seal types that accommodate minor floor irregularities. For significantly uneven floors, we can recommend a brush-style or flexible seal that creates a better fit on non-level surfaces.
