Fast, Reliable Garage Door Installation Across Westmont
Garage door installation in Westmont typically runs $700–$2,200 for a new door, and most projects are completed in a single day once permits clear. Because Westmont is unincorporated LA County territory, the permitting process flows through LA County Building and Safety rather than a city department — a detail that catches out-of-area contractors who assume standard LA city rules apply.

We’ve been driving to Westmont from Santa Monica for 22 years, and we know the difference. Greg Thompson, our owner and lead technician, has personally installed doors from 108th Street to the edges of Vermont Knolls. These post-war neighborhoods are full of 1940s–1960s tract homes with detached single-car garages built to older dimensions — 7- to 8-foot openings, low headers, and hardware that’s often original to the house. When that legacy equipment fails, you need someone who understands retrofit work, not just standard installs. Call us at (424) 347-8870 for a free estimate — we’ll come out, measure your opening, and tell you exactly what your job requires.
Why Titan Garage Door Solutions Santa Monica Is Westmont’s Preferred Garage Door Installation Company
Our Garage Door Installation team doesn’t treat Westmont like an afterthought on a broader LA route. We’re here regularly because the housing stock demands it — and because our customers here talk to their neighbors. That word-of-mouth shows in our numbers: a 4.9-star average across 439 verified reviews, with Westmont homeowners specifically citing Greg’s willingness to explain header modifications and permitting steps they didn’t know they needed.
Response time to Westmont is typically same-day or next-day for standard installations, and emergency garage door service is available when a failed spring or seized door leaves your home unsecured. We’re familiar with the county’s Lakewood and Gardena district offices for permit filing, so your project doesn’t stall waiting on paperwork that an out-of-area contractor mishandled.
The owner shows up. That’s not a slogan — it’s how we operate. Greg Thompson handles the diagnostic, the measurement, and the install itself. You’re not getting a subcontractor who’s learning your door type on the job. In 22 years, one standard.
Our Garage Door Installation Services in Westmont
New Door Installation
A full new door installation in Westmont starts with understanding what you’re working with. Most homes here were built with 7-foot or 8-foot-wide single-car openings and minimal headroom clearance — dimensions that conflict with modern standard kits. We measure twice, modify framing when necessary, and install a door that fits properly and operates smoothly. Typical cost: $700–$2,200 depending on material, insulation level, and structural modifications needed.
Single Car Door Replacement
Single-car garages dominate Westmont’s residential blocks, and they’re often the most challenging. Narrow openings with low headers require careful track selection and sometimes torsion spring systems configured for constrained spaces. We’ve replaced dozens of these in Westmont — including a 1950s one-piece wood door on 108th Street that had seized completely. The original 7-foot-wide rough opening needed header modification before we could install a new Clopay steel door with modern torsion hardware, bypassing a full frame-out that would have cost thousands more.
Double Car Door Installation
Where double-car garages exist in Westmont — often on corner lots or in small pockets of slightly newer construction — we install 16-foot sectional doors with reinforced tracks and appropriately rated spring systems. These wider spans face stronger wind loads, particularly during Santa Ana events, so we specify heavier-gauge track and robust weatherstripping to prevent panel racking and seal failure.
Custom Garage Door Installation
Carport-to-garage conversions are common in Westmont, and they create some of the most irregular openings we see. Non-standard widths, sloped ceilings, and mixed construction quality mean off-the-shelf doors won’t fit without significant adaptation. Our custom garage door installations address these realities with cut-to-fit panels, specialized track configurations, and hardware selected for your specific structure. We also handle steel doors and wood doors in custom builds, sourced from Clopay, Amarr, and Wayne Dalton product lines.

Trusted Brands We Service in Westmont
Whatever’s on your door, we know it. We’re factory-familiar with eight major brands: LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. For Westmont customers, this means we stock common parts and can source panels, openers, and hardware without extended delays. A failed opener on a 1990s Craftsman system? We can match it or upgrade you to a current LiftMaster or Chamberlain unit. Brittle torsion springs on an older Wayne Dalton door? We carry the replacement and know the wind specification for your span. Fast turnaround matters when your garage is your primary home entry point — which it is for many Westmont residents.
Common Garage Door Installation Problems We See in Westmont Homes
- Narrow openings with low headers. Most Westmont single-car garages were built to 7- or 8-foot widths with minimal headroom. Standard modern door kits assume more generous dimensions, so we frequently modify headers or specify low-headroom track systems to make the install work without major reconstruction.
- Carport conversions with irregular rough openings. DIY or contractor conversions from the 1970s–1990s created non-standard widths and out-of-square frames. Panels bind, tracks flex, and openers strain. We assess whether the opening can be corrected or if a custom door and track package is the practical solution.
- Brittle original hardware from low-humidity cycling. Westmont’s inland position means more extreme Santa Ana wind exposure than coastal communities. Dry, gusty conditions accelerate weatherstripping cracking and cause older torsion springs — already fatigued from decades of thermal cycling — to fail abruptly in fall and winter. We replace with current-spec springs rated for the actual door weight and local wind load.
- UV-degraded bottom seals and painted steel panels. Mild temperatures mean rust is rare here, but direct sun degrades rubber seals and fades factory paint on steel doors. During installation, we upgrade to UV-resistant seals and can discuss color-matched panel options from Clopay and Amarr that hold up longer in exposed conditions.

FAQs — Garage Door Installation in Westmont
Yes — because Westmont is unincorporated LA County, all permitted garage door work must be filed with LA County Building and Safety, not a city department. We handle this paperwork as part of our installation service, routing it through the county’s Lakewood or Gardena district office. Out-of-area contractors often miss this distinction and file incorrectly, causing delays. Call (424) 347-8870 and we’ll confirm whether your specific project requires permitting.
Yes, but the opening typically needs modification first. Most 8-foot Westmont openings have low headers that conflict with modern torsion spring hardware. We modify the header or specify low-headroom track to accommodate a new Clopay or Amarr steel door without a full frame-out. We replaced a seized 1950s one-piece wood door on 108th Street with exactly this approach — new steel door, proper spring system, no unnecessary reconstruction. Call for a free assessment of your opening.
We install and service eight major brands: LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. For Westmont’s older housing stock, we most commonly specify Clopay and Amarr steel doors for durability and Wayne Dalton or LiftMaster opener systems for reliable operation in modified openings. Whatever’s currently on your door, we’ve worked on it. Call (424) 347-8870 to discuss options matched to your budget and structure.
Yes, typically 15–30% more than a standard replacement due to irregular rough openings, out-of-square framing, and non-standard ceiling heights. These conversions are common in Westmont and require custom-cut panels, specialized track, and sometimes structural reinforcement before the door goes in. We assess whether correction or custom fitting is more cost-effective for your specific conversion. Estimates are free — call to have Greg evaluate your situation.
Westmont’s inland position exposes garage doors to stronger Santa Ana wind events than coastal communities, accelerating weatherstripping failure and increasing stress on tracks and springs. Dry, gusty conditions also worsen brittleness in older torsion springs. We specify heavier-gauge track, robust bottom seals, and properly rated spring systems during installation to account for this local load. If your current door rattles or gaps in wind, it’s underspecified for Westmont conditions. Call (424) 347-8870 for an upgrade assessment.
