A seal that leaves daylight at one corner only may be closing onto a slab that dipped or a door that hangs out of level.

Garage Door Weather Seal Replacement in Garland, TX
Your garage door lets in daylight under the bottom edge, water across the slab after a storm, or dust, leaves and insects along the sides. Garage door weather seal replacement renews the bottom seal, the side and top stops and, where the slab dips, the threshold, so the door closes tight again. Call about the seal on your Garland garage door before water and pests settle into the garage.
What you are seeing
Where the seal has failed
A failed seal shows from inside your garage with the door closed and the lights off.
- Light under the door
Daylight along the bottom edge means a seal flattened, torn or shrunk out of contact with the slab.
- Water on the slab
Rain runs in under the door after a storm.
- Dust and leaves
Debris piles in a line just inside the door.
- Pests
Insects, mice or snakes get in through a gap at a corner.
- Stiff, cracked rubber
The seal has hardened and split in the heat.
Loss risk
What a gap under the door lets in
A worn seal turns the gap under your door into an open path for water, pests and heat.
- Water damage
Water on the slab soaks the bottom of stored boxes, drywall and wood along the walls.
- Rotting jambs
Water reaching the wood around the opening softens the jambs and the trim the side stops fasten to.
- Nesting pests
Rodents chew through a split seal and nest in stored belongings.
- Heat and dust
A gapped door lets in summer heat and blowing dust, and warms the wall the garage shares with the house.
Property type
A corner gap on a dipped slab
A new seal alone won't close that gap, because the rubber still can't reach the floor. If your door seals on one side only, call about the seal and the level of the opening together.
Daylight under the door is an open path for the next storm: call to renew the seal before water reaches the walls.

Summer heat and the rubber on a Garland door
A closed garage in summer bakes its rubber seals until they harden, crack and pull away from the slab. If the seal on your Garland garage door feels stiff or shows splits, renewing it keeps the next storm outside.
Repair scope
What a seal replacement covers
Seal work matches the new seal to the door and to the slab it closes on.
- Bottom seal
The worn seal comes out of its retainer, and a new one sized to the retainer profile slides in.
- Retainer
A bent or rusted retainer gets a new length so the seal stays put.
- Side and top stops
Weatherstrip along the jambs and header comes off where it has hardened, split or pulled away, and new strip goes on.
- Threshold
A dipped or uneven slab can take a threshold seal so the door meets a level line.
- Door travel
The close limit and door level line up so the new seal compresses without the door reversing.
Service sequence
From a gapped door to a tight seal
Gaps mapped
Light and water paths show where the seal has failed.

The worn bottom seal and stops come out, and the retainer gets a close look.
New seal fitted
Bottom seal, stops and any threshold go on to match the door and slab.
Close checked
The door closes onto the new seal with no light at the edges, and auto-reverse still works.
Triage order
Why a gapped seal is worth fixing before the next storm
Each storm that runs under your door adds water to the slab and the walls beside it.
A seal job now keeps the fix to rubber and strip instead of jambs, drywall and stored belongings. Call from Garland or anywhere in Dallas County when you see daylight under the door.

Common questions
Garage door weather seal questions in Garland
How do you know the bottom seal needs replacing?
Close the door, switch off the garage lights and look along the bottom edge. Daylight, water marks or a line of debris along the slab show where the seal has failed.
Does a new seal fix a gap at only one corner?
Not always. A gap at one corner can come from a slab that dipped or a door hanging out of level, so the opening and your door level need a look along with the seal.
Can a worn seal let pests into the garage?
Yes. Mice and insects find the gaps a split or shrunken seal leaves, especially at the corners.
A door held by a broken spring is a door waiting to drop.
Call from Garland before a broken spring or cable strips the opener or bends the sections.
