Professional garage door dealers and installers can typically install a garage door in a few hours and are careful to make sure safety requirements are met. Installations by most homeowners or business owners typically span several days and cause much frustration. In addition, incorrect installation can void certain warranties, so we recommend a trained garage door installer to handle the job for you. One of the other services a professional garage door dealer can provide is the disposal of your old garage door if you are replacing a door.
