Choosing between a single and double garage door is one of the most important decisions Ottawa homeowners face when planning a garage door replacement. This choice affects not only your budget but also your home’s curb appeal, energy efficiency, and daily convenience for years to come.

Whether you’re upgrading an aging door, renovating your garage, or building new, understanding the key differences between these configurations will help you make the right investment for your home and lifestyle.

Before diving into comparisons, let’s clarify what we’re discussing. A single garage door typically measures 8 to 9 feet wide and 7 to 8 feet high—designed for one vehicle. A double garage door spans approximately 16 feet wide with the same height, covering an opening large enough for two vehicles.

Some homeowners with two-car garages opt for two separate single doors rather than one double door, which introduces another layer of decision-making we’ll explore in detail.

Purchase and Installation Costs

The price difference between single and double garage doors is significant. Here’s what Ottawa homeowners can expect in 2026:

As you can see, a single double door is typically more economical than installing two separate single doors, primarily because you only need one opener system, one set of tracks, and less total labour.

Opener and Hardware Costs

A double garage door requires a more powerful opener due to its weight, but you only purchase one unit. With two single doors, you’ll need two complete opener systems:

• Single opener: $350 – $700 (installed)
• Double door opener: $450 – $900 (installed)
• Two single door openers: $700 – $1,400 (installed)

For quality garage door opener installation, Amigo Door offers Liftmaster Professional openers with smart features and battery backup options suitable for any configuration.

Long-Term Maintenance Considerations

Maintenance costs favour a single double door since there’s only one track system, one opener, and one set of springs to service. Two single doors mean double the components that may eventually need repair or replacement.

However, two single doors may last longer in total because each door opens less frequently—reducing wear cycles per door compared to a double door that opens every time either vehicle comes or goes.

Manoeuvrability and Access

A double garage door provides a wide, unobstructed opening that makes parking two vehicles side by side easier. This is particularly beneficial for:

• Families with larger vehicles like SUVs or trucks
• Homeowners who store boats, trailers, or recreational vehicles
• Those who use their garage as a workshop requiring large equipment access
• Anyone who needs flexibility to angle vehicles or accommodate car seats

Two single doors, conversely, divide your space into defined bays. While this can feel more restrictive, it works well for households where each driver has their designated spot.

Structural Considerations

If you’re converting from one configuration to another, structural modifications may be necessary. Removing a centre post to install a double door requires reinforcing the header beam above—an additional cost ranging from $500 to $1,500 depending on complexity.

For custom garage door projects involving structural changes, professional assessment is essential to ensure building code compliance and structural integrity.

Heat Loss and Temperature Control

Ottawa’s harsh winters make energy efficiency a primary concern. Here’s where the configuration choice significantly impacts your heating bills:

Two single doors offer an advantage because you can open just one door at a time, limiting exposure to cold air. On blustery winter days when temperatures drop to -25°C, this means only half your garage is exposed to the elements.

A double door opens the entire space every time, allowing substantially more cold air to rush in. If your garage is attached to your home or has living space above it, this heat loss affects your whole house.

Insulation Recommendations

Regardless of configuration, Ottawa homes need properly insulated garage doors. Look for:

• Minimum R-12 to R-14 for basic protection
• R-16 to R-18 for optimal performance in our climate
• Polyurethane foam insulation rather than polystyrene for superior thermal efficiency

The traditional premium garage doors available through quality manufacturers feature R-values up to R-18, making them excellent choices for our demanding climate.

Architectural Harmony

Your garage door accounts for nearly 40% of your home’s front façade, making it one of the most impactful design elements. The right choice depends largely on your home’s architectural style:

Double doors work well with:

• Modern and contemporary homes
• Ranch-style houses with wide facades
• Properties where symmetry isn’t the primary design element
• Homes with a single, prominent garage opening

Two single doors complement:

• Traditional and colonial-style homes
• Properties where balanced, symmetrical design is important
• Carriage house aesthetics
• Homes in established Ottawa neighbourhoods with classic architecture

Design Options and Customization

Both configurations offer extensive customization options. Carriage house garage doors are particularly popular in Ottawa, offering vintage charm with modern insulation and performance. These doors work beautifully in both single and double formats.

Popular style choices include:

• Raised panel designs for traditional appeal
• Flush contemporary panels for modern homes
• Window inserts for natural light

Decorative hardware for carriage house aesthetics

Benefits of a Double Garage Door

• Lower initial cost compared to two singles
• Simpler maintenance with one track and opener system
• Maximum accessibility for large vehicles and equipment
• Single remote/app to manage
• Wider design options including full-glass contemporary styles

Benefits of Two Single Doors

• Energy efficiency through selective opening
• Redundancy if one door malfunctions, you still have access
• Privacy control for concealing storage or workshop areas
• Longer lifespan due to reduced cycle counts per door
• Classic aesthetic that suits traditional architecture

Independent operation for households with different schedules

Consider Two Single Doors If:

• You prioritize energy efficiency in our cold climate
• Your home has traditional or colonial architecture
• You want the flexibility to open just one side at a time
• Having backup access if one door fails is important
• You use part of your garage for workshop or storage you’d prefer to keep private

Consider a Double Garage Door If:

• Budget is a primary concern
• You have larger vehicles or need maximum manoeuvrability
• Your home has modern or contemporary styling
• You prefer simpler maintenance with fewer components
• You frequently need the full opening for boats, trailers, or equipment

Consider Your Future Needs

Think beyond today. Will your vehicle needs change? Might you want to convert part of your garage into a home gym or workshop? Are you planning to sell within the next few years? Real estate data consistently shows that garage door replacements offer one of the highest returns on investment among home improvements—often recouping 90% or more of costs at resale.

Whichever configuration you choose, professional garage door installation is essential. Garage door springs operate under extreme tension and can cause serious injury if mishandled. Professional installers ensure:

• Proper balance and alignment
• Correct spring tension for smooth operation
• Safety sensor calibration
• Weather seal installation
• Warranty protection
