Repair Vs. Replacement
What Is the Warranty on a New Garage Door?
There are three types of garage door warranties available with each varying in length and coverage.
Labor Warranty
This warranty is offered through your garage door installation company and lasts an average of 3–6 months after installation. It covers the cost
associated with improper installation and any defective parts during the warranty period.
Parts Warranty
This is by far the most important warranty that comes with your new garage door. It covers all of the mechanical parts that allow your door to operate and typically coincides with the quality of parts that come with your door. Warranties on different packages can range from one year to lifetime.
Finish Warranty
This warranty refers to the paint system or finish of the garage door and ranges from three years to lifetime. It protects against fading and rusting of the paint system.
Multiply the replacement price by 40%. (This percent decreases as the age of your garage door increases. Refer to the graph for percentage).
Compare this amount to the cost of your repair. If the repair cost is greater, opt for a replacement. If it’s less, choose a repair.
