Regular Garage Door Maintenance Many homeowners do not realize regular maintenance is necessary to keep their garage door in good condition; making it last longer and operate reliably and safely. Your garage door and opener warranties are contingent on you maintaining your garage door properly. So it is very important to maintain your garage door. You should have your garage door maintained rather than waiting until there is a problem before getting it fixed. Regular maintenance will prevent problems, while more expensive and stressful “repairs” fix problems after they arise. Disscount Door Service is available, often the same day you call, to help you with maintenance as well as repairs and installation of new garage doors and garage door openers.
