Weather sealing
The small job that matters more here than anywhere: the bottom seal and perimeter stops are the only thing between the garage interior and eight months of wind-driven rain. A garage that takes water at the slab line, or sucks leaves and drafts in under the door, is usually a seal problem, not a door problem.
The signs
- Daylight visible along the bottom when the door is closed
- Water marks or a wet strip inside the slab line after rain
- A bottom seal that's cracked, flattened, or gone hard
- Drafts and leaves blowing in along the edges
What the work looks like
- Bottom seal swap, matched to the door's retainer channel
- Perimeter stop replacement on the sides and header
- A threshold strip on the slab where the drive slopes into the garage: the fix for water running under a good seal
What moves the price
This is the cheap end of garage door work: seal material, a threshold if the slope needs it, and labor. Worth doing before the wet season, not after the water is already inside.
