Everything You Need to Know Before Buying a New Garage Door
Replacing a garage door is one of the highest-return home improvement projects available — real estate data consistently shows garage door replacement among the top three projects for ROI at resale, outperforming kitchen and bathroom remodels in curb appeal impact per dollar. ENTRANCIO guides every client through a structured selection process to ensure the door they install is the right door for their architecture, climate, and lifestyle — not just the door that was in stock.
Step 1: Determine Your Door Size
Garage door size is defined by the opening width and height. Standard sizes in Southern California:
| Configuration | Standard Width | Standard Height |
|---|---|---|
| Single car | 8' or 9' | 7' or 8' |
| Double car (two-car) | 16' | 7' or 8' |
| Oversized / RV | 10'–18' | 8'–14' |
| Triple car | 24' | 7' or 8' |
ENTRANCIO measures every opening before any order is placed — never rely on a previous owner's stated dimensions for a custom door.
Step 2: Choose Your Material
Steel Garage Doors
The most widely installed material in Southern California. Steel is durable, low-maintenance, and available in a broad range of panel styles and finishes. Single-skin steel (no insulation) suits garages used purely for vehicle storage. Double-skin insulated steel (polyurethane or polystyrene core) is appropriate for attached garages and climate-sensitive spaces. Steel back (full two-skin) construction provides maximum rigidity and the highest R-values available in a standard door.
Best for: most residential applications across Los Angeles and Orange County.
Aluminum Garage Doors
Aluminum is lighter than steel, corrosion-proof, and the preferred structural material for full-view glass door frames. Thermally broken aluminum extrusions are required for Title 24 compliance in California's conditioned garage spaces. Available in powder coat and anodized finishes in any color.
Best for: contemporary architecture, full-view glass doors, coastal properties in Malibu, Manhattan Beach, and Newport Beach.
Wood Garage Doors
Real wood delivers warmth and authenticity no other material replicates. Common species: Western Red Cedar (natural resistance to rot and insects), Redwood (similar properties), Hemlock (accepts stain evenly), and imported Meranti (dense, stable). Wood doors require annual or biennial sealing and painting — a maintenance commitment that pays dividends in authentic character.
Best for: carriage house style, craftsman architecture, and luxury estate projects where material authenticity is non-negotiable.
Composite Wood Garage Doors
Engineered composite — wood fiber or polymer blended into a substrate — provides the visual character of real wood with significantly reduced maintenance. Will not warp, crack, or split under Southern California's thermal cycling. The leading composite door lines are Clopay Canyon Ridge and Amarr Heritage.
Best for: homeowners who want a wood aesthetic without the maintenance commitment.
Fiberglass Garage Doors
Fiberglass is lightweight, corrosion-resistant, and can be manufactured with a realistic wood-grain texture. Less common in Southern California but an excellent choice for extreme coastal environments where steel and wood both require additional protection.
Step 3: Insulation — Do You Need It?
In Southern California's climate, garage door insulation is relevant in specific scenarios:
- Attached garage with living space above or beside it: insulated door significantly reduces HVAC load and noise transfer
- Converted or conditioned garage (gym, studio, home office): insulated door required for comfort and Title 24 compliance
- Valley locations (San Fernando Valley, Santa Clarita, Antelope Valley) with summer temperatures exceeding 100°F: insulation meaningfully reduces interior temperature
- Detached garage used for storage only: insulation provides minimal practical benefit
R-value guide: R-6 to R-10 (polystyrene, budget-tier), R-12 to R-17 (polyurethane, standard), R-18+ (polyurethane with steel-back construction, premium).
Step 4: Panel Style
See our complete panel style comparison guide for a full breakdown. The summary for new installation decisions:
- Contemporary home: long panel, flush (pole back), or full-view glass
- Traditional or craftsman home: short panel, raised-center panel, or carriage house
- Farmhouse: carriage house in composite or real wood
- Mediterranean or Spanish: raised-center in smooth steel or carriage house with arch windows
- Modern minimalist: flush (pole back) aluminum composite or Corten steel
Step 5: Color Selection
Garage door color is a permanent architectural decision — color affects the perceived width, height, and character of the entire facade.
- Match the trim color: the safest choice — the door reads as part of the envelope
- Match the siding color: makes the door disappear — appropriate for minimalist designs
- Accent color: a contrasting door (deep charcoal on a white house, warm cedar on a grey contemporary) creates a focal point
- Dark colors in inland climates: matte dark colors absorb heat — specify a door with high insulation if choosing black, charcoal, or dark brown in the San Fernando Valley or Inland Empire
ENTRANCIO provides photorealistic color visualization on your actual facade photograph before any order is placed.
Step 6: Window Inserts
Garage door windows add natural light, architectural interest, and — with the right glass selection — privacy:
- Clear glass: maximum light, no privacy
- Tinted glass: reduces heat gain and glare while maintaining outward visibility
- Frosted / obscure glass: diffused light with full privacy
- Decorative glass: reed, rain, and seeded textures for craftsman and traditional doors
- Insulated glass units (IGU): dual pane for maximum thermal performance
Window placement options: top panel only (most common), every panel, or alternating panels. ENTRANCIO includes window visualization in the design consultation.

Frequently Asked Questions: New Garage Door Installation
How long does garage door installation take?
A standard garage door replacement — removing the old door and installing a new sectional door with opener — takes 3–5 hours for a single technician team. Two-car door replacements take 4–6 hours. Custom or oversized doors may require a full day. ENTRANCIO schedules installations Monday through Saturday and completes most residential replacements in a single visit.
Do I need a permit to replace a garage door in Los Angeles?
In most Los Angeles County and Orange County jurisdictions, replacing a garage door with a same-size door does not require a permit. If the opening is being widened, the header is being modified, or a fire-rated door is being installed, a permit is typically required. ENTRANCIO's team is familiar with local requirements across all of our service area and advises clients accordingly at the estimate stage.
Can a garage door be installed on an existing opener?
Usually yes, provided the existing opener is compatible with the new door's weight, size, and spring system. ENTRANCIO evaluates the existing opener during the site measurement visit and advises whether it can be retained or should be replaced. If the opener is over 12 years old, replacing it simultaneously with the door is often cost-effective and avoids a return visit.
