Widths - in addition to doors coming in a range of styles, they can be found as double-width and single-width styles. There are some serious considerations when opting for one over the other. For example, if a homeowner decides to use a single door that covers the entire opening of a two-car garage they will have to make serious structural modifications to the entry way;
The electronics should also be inspected before or after investing in the cost of replacing the garage door panel to make sure your door will operate properly. The sensors prevent the door from closing on someone's foot or a pet. If they don't work, someone could be injured. Also check to make sure the door opener works, since you could otherwise be locked out of your garage.
Safety Inspections: Garage doors operate under a massive amount of tension. It’s the tension that makes a garage door work properly, but this tension can also pose a threat when the garage door is out of order. To ensure that your garage remains a safe place, we provide an annual, 14-point safety inspection. This can pinpoint problem areas before they spiral out of control and help you prevent costlier repairs after something goes wrong.
Test the door balance. A garage door should require only a few pounds of pressure to move it up and down. If springs wear out and lose their resiliency, a power garage door opener may need to work extra hard to lift the door. This can quickly wear out the motor on the opener. Replacing worn-out springs is usually a job for a professional technician.
Now check the springs. There will be just one on a single-car garage, two on a two-car garage. Roll-up doors are operated by torsion springs, controlled by cables on pulleys. Two-car models can be adjusted by pulling the cable further through the plate above the door, then knotting the end to hold the newly established tension. One-car roll-up door springs should only be adjusted by a professional, as there is such a great amount of tension on the one spring that you could be injured when trying to adjust it yourself. Swing-up door springs are hooked on each side of the door into special notches or holes. To adjust the tension on these springs, simply move the spring hooks to the next notch.
