What drives the price
A new garage door is a wide price range because so much depends on the choices you make. A basic single steel door is a very different number from an insulated, windowed, double-wide carriage-style door. Rather than quote a figure that won't match your situation, it's more useful to understand what moves the price.
The honest answer for any specific home is a quote — but knowing the factors below tells you where your project will land and where you can control the cost.
The biggest single cost factors are door size and material. Everything else — windows, insulation, hardware — adjusts the figure from there.
Size: single vs double
Door size is the first big factor. A single-car door is the smaller, lower-cost option. A double-wide door uses considerably more material and is correspondingly more expensive.
If your home has two single doors versus one double opening, that also affects the project — two doors means two of everything, though they're often the same standard sizes.
Material and construction
Steel
The most common choice in Ontario — durable, low-maintenance, and available across a wide price range from budget to premium. Most new doors installed today are steel.
Insulated steel
Steel doors with an insulated core. The clear choice for an attached garage in London — they hold heat far better, which matters through a long winter, and they're quieter and more rigid.
Wood and composite
Wood offers a premium look at a premium price and needs more upkeep. Composite gives a wood-like appearance with less maintenance. Both sit at the higher end.
Aluminum and glass
Modern full-view doors with aluminum frames and glass panels are a distinctive, contemporary look — and a premium-tier cost.
The features that adjust the price
On top of size and material, these choices move the final number:
- Insulation level — higher R-value costs more but pays back in an attached garage
- Windows — adding a row of windows for natural light increases the price
- Style — carriage-house and designer styles cost more than standard panel doors
- Hardware and finishes — decorative handles, hinges, and custom colours add up
- Opener — many homeowners replace the opener at the same time
- Old door removal — disposal of the existing door is usually part of the job
For a London home, insulation is the feature most worth prioritizing. An attached garage with a poorly insulated door loses real heat all winter; a well-insulated door is a comfort and efficiency upgrade, not just an appearance one.
Repair first, or replace?
Before committing to a new door, it's worth confirming you actually need one. If the panels, tracks, and frame are sound and only a spring, opener, or cable has failed, a repair is far cheaper and restores the door fully.
Replacement is the right call when the door is old, multiple panels are damaged, the door is poorly insulated, or you specifically want a new look. If you're unsure, a technician can assess the existing door and give you an honest repair-or-replace recommendation before you spend on a full replacement.
