Garage door installation in Westmont usually runs between $700 and $2,200 for a complete new door, and most homeowners choose a mid-century style that fits the neighborhood’s 1940s – 1960s stucco homes. The real difference in Westmont is space: many garages sit at the end of narrow side driveways or face an alley, so we measure for clearance before recommending any panel or opener. Call Onyx Garage Door Service at (877) 588-8251 for a free estimate, and we’ll come out, measure the opening, check the track condition, and quote you a written price before any work starts.
Why Westmont Homes Are Different
Westmont is an unincorporated pocket of South LA wedged between Inglewood and South Central, where the housing is overwhelmingly mid-century single-story stucco homes built in the post-war boom. Many of these homes have detached or attached one-car garages facing alleys and side driveways rather than the wide front-facing garages of newer suburbs. That alley-and-side-yard orientation, combined with dense lot spacing, means spring, track, and opener problems here are almost always the result of tight clearances and jockeying vehicles in narrow driveways. We regularly see panels with impact dents from a car tapped against the track while backing out, springs that failed early because the door could not travel smoothly in a slightly out-of-square opening, and openers working harder than they should because the door binds against a warped jamb. Westmont’s hot, dry inland South LA summers bake wood doors and stress opener motors, while the morning marine-layer moisture and occasional Santa Ana-driven dust accelerate rust and hinge wear on exposed metal doors facing alleys. Technicians here constantly run into alley-facing garages with no room to swing a full-size door panel and vehicles parked right up against the track, so the job is as much about working in cramped clearances as the door itself. We plan around that: we carry compact lifting equipment, we stage parts on the driveway side, and we schedule work so neighbors still have alley access.
Styles & brands we work with
Our Main Westmont Services
Most homeowners in Westmont call us for one of two reasons: a door that stopped working, or an opener that stopped responding. Both services get a dedicated Westmont page because the local conditions change the diagnosis.
Garage Door Repair in Westmont
Westmont’s alleys and narrow side driveways take a toll on doors. We see broken torsion springs, snapped cables, rollers that have ground themselves flat against bent tracks, and panels with cracks radiating from a single impact point. Because these garages are often older wood or early metal sectional doors, parts can be discontinued, and we’ll tell you honestly whether a repair makes sense or whether a replacement door is the smarter long-term move. The full repair breakdown, local pricing, and same-day options live on our dedicated page: Garage Door Repair in Westmont.
Garage Door Opener Repair in Westmont
Openers in Westmont work hard: the heat stresses circuit boards and capacitors, the dust builds up on the rail and gears, and the narrow clearances mean safety sensors get knocked out of alignment when a car clips a track. Older chain-drive openers from the 1990s and early 2000s are common here, and many can be repaired with brand-specific parts rather than replaced. If your opener is grinding, refusing to close, or reversing for no reason, see the full cost and fix list here: Garage Door Opener Repair in Westmont.

Garage Door Installation in Westmont
Garage door installation in Westmont means working with garage openings that were framed for the original 1940s – 1960s doors, and honestly, some of those frames are no longer square. The heat and morning damp have done their work on the jambs, and a new door on a warped opening will bind, chew its rollers, and stress the opener. That’s exactly why we measure first and install second: we check the header for sag, the jambs for plumb, and the side clearances for the track radius and drum height. Whether you are replacing a rotted wood door on an alley-facing garage or setting up a new opening as part of an ADU conversion, we spec the right panel, track, and hardware for a Westmont lot, not a showroom floor. This page covers the full installation process and what you can expect to pay; the service hub has a complete breakdown of every installation option we offer: Garage Door Installation.
Garage Door Replacement
Signs you need it
You are patching the same cracked panel for the second time, the bottom section is swelling from years of alley-side moisture, or the door is so far out of balance that even new springs never quite smooth it out.
What it costs in Westmont
A full garage door replacement in Westmont typically runs $700 to $2,200 depending on the material, insulation, and whether you keep the existing track.
How we do it
We remove the old door and track, inspect the opening and framing, install the new sections and hardware calibrated to your spring system, then test the full travel so the door seats evenly and quietly.
Garage Door Installation Service
Signs you need it
You have a brand-new framing ready for a garage conversion or ADU, and the opening needs a door and opener that meet current code and fit the actual clearance you have.
What it costs in Westmont
New garage door installation in Westmont starts around $700 for a basic steel model and goes up to $2,200 for insulated, high-cycle hardware and heavier-gauge steel.
How we do it
We measure the rough opening, confirm header and side clearances, supply and mount the track with shims and anchoring that account for the building’s age, then hang the sections and roll the door through its full range to tune the balance.
What Garage Door Installation Costs in Westmont
| Item | Typical range in Westmont |
|---|---|
| New door installation (basic steel, single-car) | $700 – $1,300 |

| Opener installation bundled with a new door | $250 – $550 |
How long does a new garage door installation take in Westmont?
Most residential installations finish in one day, usually four to seven hours depending on the opening condition, whether we replace the track, and how much clearance work is needed on an alley-facing garage. We’ll tell you the timeline before we start.
Can you install a new door on a garage that faces a Westmont alley?
Yes. We install doors on alley-facing garages all over Westmont, and we plan the staging and panel layout around the fact that you have no wide front apron to work from. If the door or opener can’t physically clear the side walls, we’ll tell you before you buy.

What Westmont Customers Say
"Fixed the spring properly and the door works fine. He did leave the old spring and some hardware by the side of the house, and I had to text to ask about hauling it off. They came back for it, just took a couple of days."
— David Kim"Keypad stopped working, which I assumed meant a whole new system. It was the batteries and a reprogram. He charged me the minimum service call and told me how to do it myself next time."
— Sarah Schaefer"Logic board on a 15 year old opener. He was upfront that a new opener would cost less than the board plus labor, and he wasn't wrong. No pressure either way."
