Preventative maintenance saves you money. This occurs when the door tension is not correct. It puts extra work on the garage door opener, which is not designed to lift weight. The springs do all the lifting, a general test is to lift the door manually, if it’s heavy for you to lift, than it’s heavy for the the opener. We fix this problem with a operator reinforcement bracket, which should be installed on every garage door, and by adjusting the spring tension. Call us today for your preventative maintenance.
