A double garage door covers one of the largest openings on the front of your home and handles more daily use than almost any other moving part of the building. When it is time for a replacement, getting the installation right matters — for safety, for long-term reliability, and for the appearance of your home from the street. Century Garage Door provides professional double garage door installation for residential and commercial properties across all styles, materials, and configurations.

Signs It's Time to Replace Your Double Garage Door
A double garage door that is failing puts a household’s primary vehicle access point out of commission, which makes acting on the warning signs early more important than with a single door. Century Garage Door helps homeowners evaluate their current door honestly and determine when replacement is the right call.
Signs it is time to replace your double garage door:
- Repair costs are recurring frequently, and the total spent is approaching the cost of a full new door and installation.
- The door is more than 15 to 20 years old and experiencing mechanical decline across multiple components simultaneously.
- Significant structural damage to the panels, frame, or bottom section that cannot be corrected through targeted repair.
- The door no longer closes or seals evenly across the full width of the opening, leaving gaps that allow heat, moisture, or pests to enter.
- Matching replacement panels are no longer available for the existing door model, making panel-level repair impractical.
- The existing door lacks modern safety features, including auto-reverse sensors, rolling code access, or properly rated springs for the door’s weight.
- Widespread surface deterioration, including rust, corrosion, or warping that has progressed beyond cosmetic damage and is affecting operation and structural integrity.
If you are uncertain whether repair or replacement is the better decision, Century Garage Door provides free assessments with no obligation before any commitment is made.
Double Garage Door Styles, Materials & Panel Options
Replacing a double garage door is an opportunity to make a meaningful visual and functional upgrade to one of your home’s most prominent exterior features. Century Garage Door installs double doors across all major styles and materials so your replacement fits your home’s architecture, your usage requirements, and your budget.
- Raised panel steel doors are the most widely installed style for double openings and are available in a full range of colors, finishes, and insulation levels. The raised panel profile suits most residential architectural styles and provides a clean, traditional appearance that holds up well over time.
- Flush panel doors offer a smooth, contemporary surface that complements modern and minimalist home designs. They are available with polyurethane insulation for high structural rigidity and thermal performance and are a strong choice for homeowners updating the exterior of a newer construction home.
- Carriage house doors replicate the visual character of traditional swing-out barn doors while operating as a modern overhead sectional system. Across a wide double opening, the carriage house profile creates a significant curb appeal impact and is a popular replacement choice for homes in established residential neighborhoods.
- Steel insulated doors with polystyrene or polyurethane cores are available across all panel styles and are the recommended replacement choice for double doors on attached garages. A wide double opening represents a substantial portion of the home’s thermal envelope, and an insulated door with an appropriate R-value reduces heat gain and lowers the demand on air conditioning systems serving adjacent spaces.
- Aluminum doors are a lightweight, corrosion-resistant option well-suited to properties in coastal or high-humidity environments where salt air exposure accelerates rust on standard steel surfaces. Their lower weight reduces the load on the spring system, which can extend component life in high-use double door applications.
- Wood and wood composite doors are available for homeowners who want a distinctive natural aesthetic across the full width of a double opening. Composite construction provides greater dimensional stability and moisture resistance than solid wood, making it a more practical choice in regions with significant temperature and humidity variation.
Our technicians will walk you through compatible style, material, and panel options based on your opening dimensions, your home’s exterior design, and your budget before any installation is scheduled.
Double Door Openers & Spring Systems
A double garage door is heavier and wider than a single door, which means the opener and spring system must be correctly matched to its specific weight and size to deliver safe, reliable operation. Undersized or incorrectly configured components are a common source of premature opener failure and spring wear on double door systems.
- Opener selection for a double door should account for the door’s weight, drive type, and smart connectivity preferences. Most double doors weigh between 200 and 400 pounds, depending on the material and insulation level, and the opener must be rated to handle that load reliably over tens of thousands of cycles. Belt drive openers are the preferred choice for attached garages where quiet operation inside the home is a priority. Chain drive openers are the most cost-effective option for detached garages or applications where noise is less of a concern. Smart-enabled openers with Wi-Fi connectivity add real-time access alerts, remote open and close capability, and integration with smart home platforms — a meaningful upgrade that is becoming a standard expectation for new door installations.
- Spring system selection for a double door is particularly important because the springs carry the full weight of a wider, heavier panel assembly. Most double doors use two torsion springs mounted on a shared shaft above the opening, with each spring sized to carry half of the door’s total weight. Installing a single spring on a double door, or springs that are undersized for the door’s actual weight, places excessive load on each spring and shortens service life significantly. Century Garage Door sizes and installs the correct dual-spring torsion configuration for every double door and offers high-cycle spring upgrades for households where the door is used frequently throughout the day.
Our Double Garage Door Installation Process
Century Garage Door follows a complete, structured installation process for every double door project. Our technicians handle every component from the first measurement to the final safety check, so the door is fully operational and correctly configured before we leave.
Here is what to expect:
- A pre-installation site assessment covering opening width and height, headroom and side room clearance, floor levelness across the full opening width, framing condition, and existing opener compatibility.
- Guidance on style, material, insulation level, spring configuration, and opener type matched to your specific opening dimensions and usage requirements.
- Removal and disposal of the existing door, hardware, and any components not being reused.
- Professional installation of all door panels, track sections, springs, cables, hinges, and mounting hardware to manufacturer specifications across the full double-opening width.
- Bottom seal and full perimeter weatherstripping installation to create a complete barrier at all four sides of the opening.
- Opener installation and integration covering motor unit mounting, drive configuration, safety sensor placement, limit adjustment, and remote and keypad programming.
- Dual-spring tension calibration matched precisely to the door’s total weight and height for safe, balanced operation across the full width of the opening.
- Full safety inspection covering auto-reverse sensor function, door balance across the full panel width, manual release, and limit switch calibration.
- A complete operational walkthrough covering system use, maintenance, and best practices for a double door installation specifically.
Benefits of a New Double Garage Door
A new double garage door replacement delivers improvements across safety, security, energy efficiency, and home appearance that are immediately visible and lasting over time.
Benefits of a new double garage door include:
- Modern auto-reverse sensors and correctly rated springs that restore the safety performance a worn or aging double door system can no longer reliably provide.
- Updated rolling code access technology that eliminates the fixed code vulnerabilities present in older opener systems across both remote and keypad entry points.
- Improved thermal performance through an insulated replacement door that reduces heat gain across the full width of the opening, lowering cooling demand in attached garages.
- A significant curb appeal upgrade, as a wide double door is the most visually prominent element on the front facade of most two-car garage homes.
- Quieter, smoother operation with new springs, rollers, hinges, and hardware that have not been worn through years of daily double door cycling.
- Lower maintenance demands compared to continuing to service an aging system with deteriorating components across a larger, heavier door assembly.
- Increased property value supported by the strong return-on-investment profile of new garage door installation in national remodeling cost benchmarks.

Frequently Asked Questions
How wide is a standard double garage door?
Most double garage doors range from 14 to 18 feet in width and 7 to 8 feet in height for residential applications. The most common residential double door width is 16 feet. Century Garage Door measures your specific opening during the pre-installation assessment to confirm the correct door size before any order is placed.
How many springs does a double garage door need?
Most double garage doors require two torsion springs mounted on a shared shaft above the opening, with each spring sized to carry half of the door’s total weight. A single spring on a double door is an undersized configuration that shortens spring service life and increases the risk of unbalanced door movement. Century Garage Door installs the correct dual-spring configuration for every double door and replaces both springs simultaneously to ensure balanced tension across the full opening width.
Do I need a more powerful opener for a double garage door?
Yes, in most cases. A double door is significantly heavier than a single door, and the opener must be rated to handle that load reliably over a long service life. Most double door installations benefit from a 3/4 to 1.5 horsepower opener, depending on the door’s material, insulation level, and total weight. Century Garage Door will recommend the correctly rated opener for your specific door during the pre-installation assessment.
Can I install a double garage door myself?
Double garage door installation is not a safe DIY project. The door panels are heavy, the spring system operates under significant mechanical tension, and incorrect spring sizing or track alignment creates a serious injury risk and can cause the door to fail during operation. Century Garage Door strongly recommends professional installation for all double door systems.
How long does a double garage door installation take?
Most residential double garage door installations are completed within four to six hours. Projects that include a new opener installation, custom sizing, or structural framing adjustments may take somewhat longer. Our technicians provide a clear time estimate during the pre-installation assessment so you can plan accordingly.
