If you hire a professional to install a garage door opener that you have already purchased, installation charges will be on average between 175-250 depending on the manufacturer of the opener. We, however, carry professional-grade openers at an affordable cost and are not generally available at most retail stores. If you purchase an opener with installation, the openers will, on average, range from about 350-700 depending on the model, drive mechanism, and size and weight of the garage door. We often have promotions for free installation with the purchase of one of our garage door openers, so there would not be a charge on top in this case.
