When you purchase a new garage door, the existing opener can sometimes be reused. But with so many functions and features built into today’s garage door openers, about 66% of homeowners choose to purchase a new one. The cost for a new opener typically starts around $600 and can increase depending on the opener you choose and its unique features. Openers are also considered to be a capital improvement when installed at the same time as a new door–so there is a tax saving opportunity, as well.
