The cost of installing a garage door opener is determined as much by the style of the door as any other price point. Most garage door openers will cost you between $200 and 500 dollars on their own. If you do the installation yourself you may save yourself a significant amount of money, but make sure you know how it’s done or you’ll just cost yourself time and money. Having them installed often runs around $400 all on its own, meaning that between the motor itself and the installation you’ll likely wind up spending around $1000 on your garage door opener.
