Garage door companies who replace a garage door advertise in the Yellow Pages under the listing "Doors" and offer service to both residential and commercial customers. They come to the house, appraise the garage and existing door and will give you a written estimate that includes the removal of the old door, and installation of the type of new overhead door you've chosen, plus an automatic opener. They also advertise online so you can use a search engine like Bing, Google and Yahoo to find an installation company. Type "install a garage door in (your city)" in the search box or use an online contractor referral service.
If the new garage door is part of a garage spruce up project and you want to paint the garage before the new door is installed, negotiate with the salesman that they'll come and remove the old door and allow time for you to repair and paint before they return to install the new door.
