Answering 24/7. Flat written price before work starts.
Gaps around your Houston garage door? We replace bottom seals and retainers, jamb and header seals, and floor thresholds, usually $100 to $250 for a full perimeter refresh. The payoff in this climate is immediate: drier slab, cooler garage, fewer pests, and a door that closes with a soft thud instead of a clatter.
What this covers
Sealing the biggest gap in the house
A garage door seals on four edges: a rubber astragal along the bottom, vinyl or rubber jamb seals up both sides, a header seal across the top, and optionally a threshold glued to the slab. Texas sun and Gulf humidity harden the rubber, the slab settles a hair, and within a decade most Houston doors are closing onto cracked, flattened seals that stop nothing.
Replacement is matched work: bottom seals come in different profiles, T-ends, bead sizes and retainer styles, and the right one slides into your existing retainer or we fit a new aluminum retainer where the old one is corroded. Side and top seals are cut and nailed or screwed to close the sight lines, and a threshold handles driveways that slope toward the garage.
It is honest, unglamorous work with outsized returns here: a sealed garage runs measurably cooler in a Houston August, keeps wind-driven rain off whatever you store, and removes the half-inch highway roaches and mice were using.

What it costs
Weather seal pricing
Seals are inexpensive parts fitted carefully. Typical installed ranges for Houston homes:
| Bottom seal in existing retainer | $80 to $150 |
|---|---|
| Bottom seal with new retainer | $130 to $220 |
| Jamb and header seal set | $90 to $180 |
| Full perimeter refresh | $150 to $300 |
| Floor threshold, installed | $90 to $170 |
| Rodent-resistant upgrade | add $40 to $90 |
A perimeter refresh is quoted as one flat number after we measure the door. If the real problem is a racked door closing unevenly, we will say so, because new rubber cannot fix crooked steel.

Choices to make
The seals, piece by piece
Bottom seal and retainer
The workhorse: a new rubber astragal in your retainer, or retainer and seal together where aluminum has corroded.
Jamb and header seals
Vinyl or rubber perimeter seals that close the sight-line gaps up the sides and across the top.
Floor threshold
A glued slab-mounted ridge for driveways that slope toward the door or garages that catch sheeting rain.
Rodent-resistant seals
Reinforced bottom and corner guards for garages where mice have already found the standard rubber.
Ways this job shows up
Garage Door Weather Seal Replacement jobs we handle
Bottom seal and retainer
Bottom seal and retainer work is the core job: matched profile, fresh rubber, solid contact across the full width.
Jamb and perimeter seal
Jamb and perimeter sealing closes the side and top gaps that let wind-driven rain and dust trace the door outline.
Threshold seals
Thresholds give sloped driveways a ridge to stop sheeting water before it reaches your stored boxes.
Rodent-resistant seals
Rodent-resistant seals end the chewed-corner cycle in garages where standard rubber keeps losing.
Before you call
Signs your seals are done
- Daylight visible under or beside the closed door from inside the dark garage.
- Water lines or damp patches on the slab after rain, especially at the corners.
- Cracked, flattened or rock-hard rubber along the bottom edge.
- Leaves, dust and insects appearing inside despite the door staying closed.
- A garage noticeably hotter than it used to be through summer afternoons.

Houston conditions
Seals against Houston weather
Fifty inches of rain a year, much of it arriving sideways in storm cells, makes the bottom seal a flood-control device as much as a draft stopper. Slab-on-grade garages across Houston collect water at the door line first, and a proper seal plus threshold is the difference between a damp line and a soaked floor.
Then there is summer: around 94 days a year over 90 degrees, with attached garages soaking heat into the rooms beside them. Fresh perimeter seals will not turn a garage into a cold room, but paired with an insulated door they noticeably cut what the house absorbs.

Straight answers
Questions about garage door weather seal replacement in Houston
Five to ten years is typical here, shorter on south- and west-facing doors that take full sun. Heat hardens the rubber until it cracks rather than compresses, at which point it seals nothing.
Either the slab has settled at that corner, the driveway sheets water toward it, or the door is closing slightly unlevel. A corner-matched bottom seal or a threshold handles the first two; an unlevel door gets rebalanced, not just resealed.
They remove the open invitation. Standard seals close the gaps insects use; rodent-resistant versions add reinforcement where mice chew. Sealing will not evict pests already living inside, but it ends the open door policy.
It helps, measurably, by stopping hot outside air from washing in under and around the door. For a garage you actually work in, the bigger lever is an insulated door, and we will tell you honestly which investment fits your use.
Only when the aluminum is corroded, bent, or the wrong profile for modern seals. If yours is sound, new rubber slides into it and you pay for the seal alone.
A seal protects wood; it cannot resurrect it. Minor softness can be treated and sealed over, but a rotted bottom rail is section-replacement territory, and we will show you that price honestly.
A rubber or vinyl ridge about half an inch tall, glued to the slab where the door closes onto it. Cars roll over it without noticing; sheeting rainwater does not.
A bottom seal is about 30 to 45 minutes; a full perimeter refresh with threshold runs about an hour. Same-visit completion from truck stock is the norm.
