At Cookson Door Sales, we firmly believe that the installation of a garage door is not a do-it-yourself job. 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. Installations by most homeowners typically span several days and cause much frustration. In addition, incorrect installation can void certain warranties, so we recommend a professional handle the job for you.
