Garage door installations typically take some serious ladder work with fairly heavy objects. Genie
One question almost everyone has when looking at smart garage doors is what installation looks like -- and how hard it is. That depends what kind of smart garage door you get. Retrofits replace or add onto your current garage door electronics, and are a very easy DIY project.
However, there's a trick to retrofits: They don't work on every garage door brands, they are limited by garage door design and they may not work with garage doors that are a few decades old. Unfortunately, that puts them out of the running for quite a few homeowners.
The other option is a full smart garage door kit, which doesn't replace the door itself but rather replaces the garage door motor and usually some of its tracking. These kits are rated for height (usually the standard 7-foot garage door) but may come with extension options. The motors also have horsepower ratings that should match the needs of your garage door (check your old motor for details).
A full garage door kit is also a DIY project but only if you're comfortable around ladders and somewhat heavy metal tracks that need to be installed on the ceiling. That can be a lot of work for one or even two people, but you do have the option to look up local garage door services to see what they charge for an installation.
