Torsion spring

A tightly wound metal coil mounted above the garage door that counterbalances the door’s weight, letting it open and close smoothly. When one breaks—common in West Hollywood’s salty air—your door may feel heavy or refuse to move. Replacing torsion springs requires special tools and safety know-how; our technicians handle this risky job daily with zero surprises.

Extension spring

Long, stretchy springs mounted on either side of the door track that extend and contract to lift the door. Unlike torsion springs, they’re visible and easier to spot when worn or snapped. If yours snaps mid-lift, the door can crash down—dangerous in tight West Hollywood driveways. Always call a pro for replacement.

Track

The metal rails that guide your garage door up and down. Bent or misaligned tracks—often caused by a door hitting the frame—make the door stick, rattle, or derail. In West Hollywood’s older homes, tracks can warp over time. A quick realignment check can save you a costly replacement.

Roller

Small wheels attached to the door’s sides that roll inside the track, keeping the door aligned and reducing friction. Plastic rollers wear out faster in heat and humidity, while steel ones last longer but can squeak. If your door jerks or skips, dried-out rollers are usually the culprit.

Opener

The electric motor that powers your garage door open and shut. Modern openers come with smart features like Wi-Fi control, but older models can strain under heavy doors or fail in power outages. If yours hums but doesn’t move, the opener may need a tune-up or replacement—we’ll diagnose it for free.

Photo-eye sensor

Safety device mounted near the bottom of the door that detects obstructions (like a bike or pet) and reverses the door to prevent crushing. If your door won’t close and flashes a light, the sensors are likely dirty or misaligned—common in dusty West Hollywood garages. A quick wipe often fixes it.

Limit switch

A small control inside the opener that tells the door when to stop opening or closing. If set too tight, the door slams shut; too loose, it won’t fully close. In West Hollywood’s tight spaces, improper limits can damage the door frame or opener. We calibrate them precisely every time.

Weatherstripping

The rubber or vinyl seal along the door’s edges that blocks drafts, dust, and pests. Cracked or missing weatherstripping lets in West Hollywood’s salty air and critters, raising energy bills and damaging the door. Replacing it is a quick, affordable fix that pays off in comfort and savings.

R-value (insulation)

A number measuring how well garage door panels resist heat flow—higher R-values mean better insulation. In West Hollywood’s 90°F summers, an insulated door (R-12 to R-18) keeps your garage cooler and reduces AC costs. Uninsulated doors can turn your garage into an oven; we install top-rated panels for less than you’d expect.

Cable drum

The grooved wheel at the end of the torsion spring that the lift cable wraps around. If the cable slips or the drum cracks, the door can drop suddenly—extremely dangerous. West Hollywood’s older doors often have worn drums; replacing them is part of a spring replacement job.

Bottom seal

The thick rubber strip at the bottom of the door that seals the gap between the door and driveway. A worn seal lets water, dirt, and critters into your garage—especially problematic in West Hollywood’s rainy winters. Replacing it is a 30-minute job that protects your belongings and floors.

Travel module

The electronic brain inside modern openers that controls door movement, safety features, and smart functions. If your opener beeps randomly or the door moves erratically, the travel module may be failing. In West Hollywood, power surges from nearby studios can fry these modules—we replace them fast.

Trolley

The part of the opener that connects to the door and pulls it along the track. If the trolley is loose or detached, the door won’t open or close smoothly. In West Hollywood’s tight garages, trolley issues often stem from misaligned tracks or worn opener chains.

Manual release

A red handle or rope inside the garage that disconnects the door from the opener, letting you open or close it by hand during a power outage or opener failure. If your manual release is stuck or missing, you’re one storm away from being locked out. We always check this during safety inspections.

Bearing plate

The metal plate that holds the torsion spring in place above the door. If the bearing plate cracks or the bolts loosen, the spring can explode—creating a serious hazard. In West Hollywood’s older homes, corrosion weakens these plates over time; we replace them as part of spring jobs.

Strut

A horizontal metal beam reinforcing the door panel to prevent sagging or warping, especially on wide or heavy doors common in West Hollywood’s larger homes. If your door looks wavy or won’t stay aligned, a broken strut is likely to blame. We reinforce or replace struts during door repairs.
