Door Construction Among doors of the same size, the construction of the door makes a huge difference in price. On the low end you have plain, single-faced steel garage doors which run around $400. Add more features such as insulation, thicker steel, or windows and your costs will obviously go up.
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.
Why Does My Garage Door Stop and Go Back Up? A garage door that stops and goes back up is usually due to malfunctioning infrared sensors. If there is such an issue, you can see one of the sensor lights blinking. Malfunctioning sensors can be caused by a blockage, dirty eyes, loose wires, or just bad sensors in general.
