New Garage Door Installation in London, Ontario: A Homeowner's Walkthrough
A new garage door is one of the highest-return upgrades a London homeowner can make — it transforms curb appeal, cuts drafts, and quietly boosts resale value. This walkthrough covers everything from choosing a material to what happens on installation day, so you know exactly what you are paying for.
A professional new garage door installation in London, Ontario typically takes 3 to 5 hours for a standard single or double door and costs $1,200 to $3,500+ installed, depending on size, material, insulation, and whether old hardware is removed. A good install includes haul-away of the old door, new tracks, rollers, springs balanced to the door's weight, and a safety test. Get a fixed quote at (226) 781-1003.
When a new door beats another repair
Repairs almost always cost less than replacement — right up until the point where you are fixing one thing after another. Consider a new door when:
- The door is 20+ years old and parts are getting hard to source.
- Repair costs are climbing past roughly half the price of a new door.
- Panels are dented, rotted, rusted, or the door has been hit by a vehicle.
- You want the energy savings and quiet operation of a modern insulated door.
- You are selling and want the curb-appeal lift — new doors return a large share of their cost at resale.

Choosing the right material for London's climate
Material is the single biggest driver of price, looks, and how the door holds up to London winters. Here is the honest comparison.
| Material | Look & durability | Best for |
|---|---|---|
| Steel (insulated) | Low maintenance, dent-resistant grades available | Most London homes — best value |
| Composite / faux wood | Wood look without rot, mid-high cost | Curb appeal without upkeep |
| Real wood | Premium, needs refinishing | Heritage and high-end homes |
| Aluminum & glass | Modern, light, full-view glass | Contemporary builds |
For most London homeowners, an insulated steel door hits the sweet spot of price, durability, and warmth. If you want the wood look near Wortley Village's older streets without the maintenance, composite is worth the premium. Our how to choose a garage door guide goes deeper on styles.
Insulation and R-value: what matters here
If your garage is attached — or you use it as a workshop or gym — insulation is not optional in London. An insulated door keeps the space warmer, cuts noise, and protects the door from warping.
Understanding R-value
R-value measures resistance to heat flow; higher is better. A single-layer non-insulated door is roughly R-0 to R-2. A good insulated steel door runs R-12 to R-18, and premium polyurethane-core doors reach R-18+.
- Detached, unheated garage: R-6 to R-10 is usually plenty.
- Attached garage with rooms above or beside it: aim for R-12 to R-18.
- Heated workshop or gym: go for the highest R-value polyurethane core you can budget.
Polyurethane-core doors are also noticeably quieter and more rigid than polystyrene, which matters if there is a bedroom over the garage.
What happens on installation day
A professional install is more than hanging panels. Here is the sequence a Garage Door London crew follows.
Inside a proper installation
Removal and disposal
The old door, tracks, and springs come down and are hauled away — you should not be left with a pile of scrap. We also inspect the opening for rot or out-of-square framing that could affect the seal.
New tracks, rollers, and hardware
Reusing bent tracks or worn rollers is a false economy. A quality install includes new tracks, nylon rollers for quiet operation, and hinges rated to the door.
Springs balanced to the door
This is where experience shows. Springs must be matched to the exact weight of your new door so it lifts smoothly and the opener is not overworked. A poorly balanced door fails early — the same principle we explain in how long garage door springs last.
Weather sealing and final test
New bottom seal and side weatherstripping keep London's wind and snow out. We finish by cycling the door, testing the auto-reverse safety, and walking you through the warranty. If you are pairing the door with a new opener, our opener replacement guide covers the options.

Most standard installs are completed in a single visit. Ask any installer about warranty before you book — a reputable one stands behind both the manufacturer's coverage on panels and springs and their own workmanship, in writing. See full pricing context in our new garage door cost guide.

Frequently asked questions
A standard single or double door is usually installed in 3 to 5 hours in one visit, including removing and hauling away the old door. Adding a new opener adds about an hour.
Most installed doors run $1,200 to $3,500 in 2026. Insulated steel — the best value for most homes — typically lands at $1,500 to $2,400 for a single and $2,200 to $3,500 for a double. Composite and wood-look doors cost more.
For an attached garage, especially with living space above or beside it, aim for R-12 to R-18. A detached, unheated garage is usually fine at R-6 to R-10. Polyurethane-core doors give the highest R-values and are quieter.
Insulated steel is the best all-round value — durable, low maintenance, and warm. Composite (faux wood) gives the look of wood without rot or refinishing, for a higher price. Real wood is premium but needs regular upkeep.
Yes. A new garage door consistently returns a large share of its cost at resale and is one of the most visible curb-appeal upgrades. See our curb appeal guide for the details.
