Of all the sections in garage doors, the bottom one needs to be replaced most often. Since this section is closest to the garage floor, it absorbs the most amount of water and is eaten more frequently by little critters.
30 years Your Garage Door Should Serve You Well for Decades A modern garage door's original panels should last at least 30 years before replacement makes its way onto your to-do list. Garage door openers, on the other hand, will last between 10 and 15 years.
Can I reuse the old rails and parts when installing a new garage door opener? Although your new garage door opener may appear similar in design to your old opener, our recommendation is that you replace the entire opener. This includes mounting hardware, rails, wired door controls and wireless remote devices.
