Garage doors are made up of multiple sections, and damage to one panel doesn’t always mean you need to replace the entire door.

But can you replace one section of your garage door?



The short answer is yes, in most cases.

However, the process depends on factors like the type of door, the availability of replacement panels, and the extent of the damage.

Let’s explore the details to help you decide.

When Can You Replace a Single Section of a Garage Door?

1. Minor Damage

• Examples: Dents, scratches, or a cracked panel.
• Feasibility: If the damage is confined to one section, replacing it is often a cost-effective solution.

2. Compatible Replacement Panels

• What to Consider: The availability of a matching panel is crucial. Older or custom doors may have discontinued designs, making replacements challenging.

3. Structural Integrity

• Why It Matters: If the damage affects the door’s frame or hinges, replacing a single section might not restore full functionality.

Cost of Replacing a Garage Door Section

The cost varies based on the material, size, and design of the door.

Material Estimated Cost

Steel Panels$150–$300 per section

Aluminium Panels$200–$400 per section

Wooden Panels$250–$500 per section

Custom Panels$500–$1,000+ per section

Additional costs may include labour ($100–$200) and any necessary hardware replacements.

Examples and Case Studies

Case Study 1: Steel Panel Replacement in Auckland

A homeowner in Auckland had a dented bottom panel caused by a bicycle accident.

Case Study 2: Custom Wood Panel in Christchurch

A Christchurch resident needed to replace a section of their custom wooden garage door.

Although expensive, it preserved the door’s unique design.

Case Study 3: Outdated Design in Wellington

In Wellington, a homeowner with an older aluminium door faced difficulty finding a matching panel.

They ultimately opted for a full door replacement at $1,200, as the repair was not feasible.

When Should You Replace the Entire Garage Door?

1. Extensive Damage

• If multiple sections are damaged, a full replacement may be more cost-effective.
• Example: Severe storm damage affecting structural integrity.

2. Age of the Door

• If your door is over 15 years old, consider replacing it for better efficiency and aesthetics.

3. Availability of Parts

• Discontinued designs or unique finishes may make it difficult to find a matching section.

How to Replace a Garage Door Section

1. Identify the Panel

• Note the brand, model, and design specifications. Take photos and measurements to ensure compatibility.

2. Consult a Professional

• While DIY replacements are possible, hiring a professional ensures the job is done safely and correctly.

3. Check for Warranty Coverage

• Some manufacturers offer warranties that may cover the cost of a replacement panel.

DIY vs. Professional Replacement

DIY Replacement

• Pros: Lower cost, more control over the process.
• Cons: Requires tools, time, and knowledge. Mistakes can compromise safety.

Professional Replacement

• Pros: Ensures proper installation and functionality.

FAQs About Garage Door Section Replacement

1. Can all garage door panels be replaced?

Not always. The availability of matching panels depends on the door’s age, design, and manufacturer.

2. How long does it take to replace a section?

Most replacements take 1–2 hours, depending on the complexity of the repair.

3. Will the new section match the rest of the door?

Exact matches may be challenging due to wear, fading, or discontinued designs. Painting or refinishing can help blend the new panel with the existing ones.

Conclusion - Can I Replace One Section of My Garage Door?

In most cases, replacing a single section of your garage door is possible and cost-effective, especially for minor damage or newer models with available replacement panels.

However, for older doors or extensive damage, a full replacement may be the better choice.
