Installing a garage door isn't as simple as installing a regular door. Not only can it be difficult, but it can also be dangerous. But if you're handy, you may want to know how to install a garage door yourself.
Installing a manual door is much easier than installing an automatic one because a manual one is so much lighter and doesn't require a motor or cables. But if you find a solid wood door, or another heavy one that you really love, it's going to have to be automatic.
