Your garage door has reached the point where another repair no longer feels worth it.

Maybe the bottom panel is rusting.

Maybe the door shakes every time it opens.

Maybe the springs, rollers, tracks, and opener have all started showing their age at the same time.

So you start pricing replacement and immediately notice a major difference between a single-car garage door and a double-car garage door.

A 2-car door costs more.

That part is obvious.

What is less obvious is that the added cost is not simply because yo u are buying twice as much steel.

A wider garage door needs different reinforcement, heavier spring balancing, stronger hardware, more careful installation, and in Florida wind-load considerations that can become increasingly important as the opening gets larger.

For Jacksonville homeowners in 2026, a typical installed single-car garage door may fall roughly around $700 to $2,200, while double-car doors commonly move into the $1,200 to $3,000+ range, depending on insulation, wind rating, material, design, and installation requirements. Florida-wide pricing can climb considerably higher for premium impact-rated or architectural doors.

So what exactly are you paying for?

How Big Is a 1-Car Garage Door?

A standard single-car garage door is commonly:

8 or 9 feet wide by 7 feet tall.

That is enough space for one typical vehicle and creates a relatively manageable opening for the garage-door system to support.

Because the door is narrower, it generally requires:

• Less panel material
• Lighter spring balancing
• Fewer or lighter reinforcement struts
• Shorter tracks and structural spans
• Less labor to maneuver during installation

That usually makes a single-car garage door the simpler and less expensive replacement.

Florida pricing guides for 2026 put many standard single-car steel doors around $950 to $1,600 installed, with wind- or hurricane-rated versions often reaching approximately $1,400 to $2,200 depending on specifications.

Jacksonville and North Florida can sometimes fall below South Florida pricing because local wind and impact requirements differ by location and property conditions.

How Big Is a 2-Car Garage Door?

A typical double-car garage door is approximately:

16 feet wide by 7 feet tall.

Some are 18 feet wide or taller.

That additional width changes the engineering.

A wide garage door has a much larger surface exposed to wind pressure. It also has a longer unsupported span across each panel.

Without sufficient reinforcement, the door can flex considerably more than a narrower single-car door.

That is why wide doors may need:

• Additional horizontal reinforcement struts
• Heavier tracks
• Stronger hinges
• Higher-capacity spring systems
• More robust jamb attachments
• Different wind-load engineering

Florida product-approval documents show that the gauge and quantity of steel reinforcement can change according to both the door height and required wind-load resistance.

That is one reason a 2-car garage door should not simply be viewed as a larger version of the same product.

How Much Does a 2-Car Door Cost?

Current 2026 Florida pricing puts many standard 16- to 18-foot steel garage doors around $1,400 to $2,500 installed.

Wind-rated double-car doors may run approximately $2,000 to $5,000, while higher-end insulated, impact-rated, wood, glass, or custom architectural doors can rise substantially beyond that.

That means a basic example might look like this:

Single-car standard steel door: $950-$1,600
Double-car standard steel door: $1,400-$2,500
Single-car hurricane-rated door: $1,400-$2,200
Double-car hurricane-rated door: $2,200-$3,500+

Those are starting ranges not guaranteed Jacksonville quotes.

The final number depends heavily on the exact opening, product approval, insulation level, finish, hardware, opener, and structural requirements.

Why Isn’t a 2-Car Door Exactly Twice the Price?

This works both ways.

A double door usually uses close to twice the panel area.

But the installation does not necessarily require twice the labor.

A technician is already traveling to the property.

The old door is already being removed.

Tools are already set up.

The opener and electrical connection may already exist.

So a 2-car door may cost substantially more than a single door without necessarily costing exactly twice as much.

However, wide doors can require heavier hardware and more reinforcement, which pushes the price back upward.

That is why pricing does not scale perfectly by square footage.

The Springs Are Different

Garage door springs are not one-size-fits-all.

They are selected to counterbalance the actual weight of the door.

A larger insulated double-car door may weigh considerably more than a basic single-car steel door.

That means the replacement may need:

• Larger torsion springs
• Two springs instead of one
• Different drums
• Stronger cables
• Different spring-cycle ratings

A reputable replacement quote should include a spring system correctly matched to the new door rather than simply reusing old springs because they happen to fit.

Current Florida installation pricing commonly includes a new spring system as part of a complete door replacement.

That matters because a beautifully installed new door with incorrectly sized springs will not operate correctly.

Can You Reuse the Existing Garage Door Opener?

Sometimes.

Replacing the garage door does not automatically mean the opener needs replacement.

If your existing opener is relatively new, reliable, compatible, and properly sized, it may continue working with the new door.

But this deserves more attention with a 2-car door.

A larger insulated or wind-rated garage door may be heavier than the door being removed.

That does not mean the opener should lift the full weight—the spring system should counterbalance most of it—but the opener still needs to be compatible with the new setup.

Florida cost guides suggest replacing an incompatible opener can add roughly $350 to $650 or more, depending on model and features.

This is also a convenient time to consider:

• Wi-Fi control
• Battery backup
• Quiet belt drive
• Camera integration
• New safety sensors

If the opener is already 12 or 15 years old, combining both replacements may make more sense than paying for another service visit a year later.

A 2-Car Door Is Harder to Physically Install

Installation logistics matter.

A 9-foot door section is relatively manageable.

A 16- or 18-foot section is another story.

The panels are longer, heavier, and more awkward to move through a driveway and garage.

Installers need adequate workspace.

That means homeowners should generally:

• Move vehicles out of the garage
• Clear storage away from the tracks
• Remove bicycles and shelving near the opening
• Provide clear access to the opener
• Keep children and pets away from the work area

For a double door, installers may need substantially more open floor and driveway space simply to stage the new sections safely.

A crowded garage can slow the installation even when the door itself is straightforward.

Florida Wind Ratings Change the Conversation

For Jacksonville homeowners, the garage door is not merely cosmetic.

It is a large exterior opening that must be matched to applicable wind-load requirements.

Florida product approvals distinguish between single- and double-car door configurations and list specific positive and negative design pressures for approved systems.

That means you should not shop only by:

“I need a 16×7 door.”

The contractor also needs to determine the appropriate design pressure and approved product configuration for the property.

A wider door can require different reinforcement than the same model in a narrow opening.

The tracks, brackets, fasteners, jamb attachments, and reinforcement are part of that approved system.

That is particularly important during storm season.

Wind-Rated and Impact-Rated Are Not the Same

This is another area where homeowners can accidentally compare the wrong quotes.

One contractor may quote a wind-rated door.

Another may quote an impact-rated door.

The second estimate may be considerably higher.

That does not necessarily mean the contractor is overcharging.

Florida product approvals clearly distinguish doors that meet specified wind pressures from configurations that also qualify as impact resistant.

Ask each contractor to provide the exact:

• Manufacturer
• Model
• Florida Product Approval number
• Design pressure
• Impact rating, if applicable
• Insulation value

Otherwise, you may be comparing two very different products.

What Happens to the Old Door?

Do not automatically assume disposal is included.

Many full-service contractors include removal and haul-away.

Others add a separate fee.

Current Florida pricing examples put old-door haul-away at around $50 to $75 in some installations.

This is a small expense compared with the door itself, but it is exactly the kind of charge that can make the final invoice higher than the estimate you thought you accepted.

Ask before signing:

“Does this price include removal and disposal of my old door?”

Should You Replace Two Single Doors With One Double Door?

That is a completely different project.

Some garages have two separate single-car doors divided by a structural center column.

Homeowners occasionally want to remove that center support and install one large double door.

That is not simply a garage-door replacement.

The center section may be supporting structural loads from the wall or roof above.

Removing it can require:

• Structural engineering
• A new header
• Framing modifications
• Exterior finish repair
• Electrical changes
• Permits and inspections

Do not let a garage-door installer simply remove a center post without determining whether it is structural.

The convenience of a wider opening can be attractive, but the conversion can cost far more than replacing two existing single doors.

Which Replacement Usually Makes More Sense?

If you already have a single-car opening, replacing it with another correctly sized single-car door is typically straightforward.

If you already have a double opening, replacing it with another double door is usually simpler than altering the structure.

The real decision is often about specifications:

Basic or insulated?

Wind-rated or impact-rated?

Standard steel or premium design?

Reuse the opener or replace it?

Those choices often affect cost more than the installation labor itself.

The Bottom Line

A 1-car garage door replacement is usually the cheaper and easier project.

For 2026, homeowners may see many single-car replacements starting around $950 to $1,600 for standard steel, while double-car replacements commonly run around $1,400 to $2,500, with wind-rated and premium systems increasing both ranges.

But don’t choose a garage door based on width and price alone.

For a Jacksonville home, verify:

The wind rating.

The reinforcement.

The spring system.

The opener compatibility.

The product approval.

The haul-away cost.

And exactly what installation work is included.

Because the real difference between a 1-car and 2-car garage door isn’t simply eight extra feet of steel.

A wider opening means more load, more reinforcement, heavier hardware—and more reason to make sure the entire door system is designed to work together.
