Garage Door Bottom Track Replacement in Dallas, TX
The bottom track (a.k.a. seal retainer) is the aluminum extrusion that holds your door’s weather seal. When it corrodes, bends, or pulls loose, the seal can’t seat against the floor—letting water, rodents, and hot Texas air pour into the garage. Modern retainers also anchor heavier bulb or T‑style rubber seals that boost energy efficiency and meet today’s tighter building codes.
Industry guides recommend replacing the track and seal every 5–10 years, sooner if you notice daylight, drafts, or rust. Ignoring damage risks panel rot, off‑track rollers, and opener strain. Supreme Garage Door Repair delivers turnkey garage door bottom track replacement across Dallas, restoring a tight, level seal in a single visit.
Signs You Need a New Bottom Track
Visible daylight under the closed door
Water, dust, or insects entering along the floor line
Bent or crushed aluminum from vehicle impact
Corroded screws or flaking metal along the retainer
Door shakes or binds at the bottom rollers
If any of these appear, stop operating the door and schedule service—continued use can warp panels or pull the door off its vertical tracks.

Garage Door Bottom Track Replacement - FAQ
Can I just replace the rubber seal and keep the old track?
If the retainer is straight and rust‑free, yes. But a warped or corroded track won’t hold a new seal firmly, and gaps will reappear. We inspect and recommend the right solution.
How long will a new track and seal last?
Quality aluminum retainers and EPDM seals typically last 5–10 years in North Texas climate, provided the door stays balanced and debris is cleared regularly.
Does bottom‑track replacement affect door balance?
Yes. Removing the bottom section changes weight distribution. We always re‑tension springs and verify balance after installation to protect the opener and rollers.
Will a new bottom seal improve energy efficiency?
Absolutely. A tight seal blocks hot air infiltration and keeps conditioned air inside, reducing HVAC load and keeping the garage up to 10 °F cooler in summer on average (DOE studies on weather‑sealing doors).
