We recommend the installation of your garage door by a trained installer. A garage door is the largest moving object in your home and because of the large number of small parts; its installation is highly technical. Connecting the springs can be particularly dangerous and proper installation is critical to the performance of your door. One of the other services a professional installer can provide is the disposal of your old door, if you are replacing a door. Professional installers can typically install a door in a few hours and are careful to make sure safety requirements are met. In addition, incorrect installation can void certain warranties, so we recommend a professional handle the job for you.
