Torsion spring
A tightly wound metal coil mounted above the garage door that counterbalances the door’s weight, letting it open and close smoothly. Unlike extension springs, torsion springs twist instead of stretch, making them safer and longer-lasting. If yours snaps, the door can crash down—call a pro immediately. Learn the difference between springs before you DIY.
Extension spring
A long, stretched spring running parallel to the door tracks that helps lift the door by extending and contracting. These springs are cheaper but wear out faster and can snap dangerously. They’re common on older Westport homes and often need replacement every 7–12 years.
Track
The metal rails—usually two vertical and one horizontal—that guide your garage door up and down. Bent or misaligned tracks cause jerky movement or gaps that let in cold Westport winters. A pro can realign or replace tracks to keep your door running straight.
Roller
Small wheels attached to the door’s sides that roll inside the tracks, carrying the door’s weight as it moves. Nylon rollers last longer than steel in Westport’s salty coastal air, but they wear out over time and can squeak loudly before failing.
Opener
The electric motor that powers your garage door’s movement, mounted on the ceiling or wall. Choose between chain-drive (cheaper but noisy) or belt-drive (smoother and quieter) models. Compare your opener options before upgrading.
Photo-eye sensor
The small infrared beam near the bottom of your garage door that stops the door from closing if it detects an obstacle. Westport’s damp air can fog the lenses—clean them monthly and test by waving a broom in front to ensure safety.
Limit switch
A safety setting inside the opener that tells it when to stop the door from opening or closing. If your door stops too early or won’t close fully, the limit switch may need adjustment—best left to a pro to avoid damage or injury.
Weatherstripping
The rubber or vinyl seal along the sides and bottom of your garage door that blocks drafts, pests, and rain. Westport’s coastal humidity and winter winds make high-quality weatherstripping a must—replace cracked strips to save on heating bills.
R-value (insulation)
A number showing how well garage-door insulation resists heat flow; higher R-values mean better insulation. For Westport’s variable climate, an R-12 to R-16 door keeps your garage warmer in winter and cooler in summer, cutting energy costs.
Cable drum
The round spool that winds and unwinds the lift cable as the door opens and closes. If the drum is cracked or the cable slips, the door can drop suddenly—replace both at the same time for safety.
Bottom seal
The thick rubber strip at the very bottom of your garage door that seals the gap between the door and the driveway. Over time, it cracks or flattens, letting water and critters inside. Replace it every few years to keep your garage dry.
Travel module
The electronic brain inside modern openers that controls door movement, speed, and safety features. If your opener acts erratically, the travel module may need reprogramming or replacement—our Westport techs can diagnose it fast.
Trolley
The part that connects the garage door to the opener’s drive system, moving the door along the track. If the trolley is loose or misaligned, the door may jerk or refuse to open—tightening or realigning it restores smooth operation.
Manual release
The red cord or handle inside your garage that disconnects the door from the opener in a power outage or emergency. Pull it gently to operate the door by hand; remember to re-engage the opener afterward to avoid damage.

Frequently Asked Questions

Why does my Westport garage door make a grinding noise only in winter, and is it serious?

Cold air thickens the grease in your torsion spring or opener gears, causing a grinding sound. If it’s a spring, the noise often precedes failure—schedule a spring inspection before it snaps. A quick lube with garage-door grease can quiet things down temporarily.

How often should I replace the weatherstripping on my Westport garage door facing the Long Island Sound?

Check your bottom seal every 6 months—salt air and UV rays degrade rubber fast. If it’s cracked, flattened, or peeling, replace it to block drafts and keep critters out. A pro can install a marine-grade seal built for coastal climates.

Can I adjust the photo-eye sensors myself if my Westport garage door won’t close on foggy mornings?

Clean the lenses first with a dry cloth—salt spray and fog obscure them quickly. If cleaning doesn’t help, the sensors may need realignment; misaligned beams can trick the opener into thinking there’s an obstacle. Call us for a quick fix before school traffic piles up.
