As a door expert witness I am called upon many times a year to evaluate garage door injuries. Garage doors come in many shapes and sizes. Their functions range from basic security of an area to cosmetic concealment. Most doors can be broken down into a few basic styles or categories. Typical modern garage doors for residential applications tend to be predominantly of the overhead sectional variety. That style of door comes in many configurations materials levels of insulation and a wide range of appearance possibilities. They are available as a prefabricated kit or built as a custom design to complement the dacor of any building. Commercial warehouse type installations often dictate higher security requirements. A good choice for this security type of door is the "roll-up" style that resembles a roll top desk type of door. This door can be manufactured with a variety of materials that can be as strong as the adjacent walls making forced entry through this opening very difficult. Other common commercial installations include light weight aluminum single or sectional panel doors. These doors function more for closing off an already secured area than for assuring point security.
The spring is perhaps the most undervalued part of a garage door initially but makes its value known very quickly. Low-cost doors tend to use extension springs. Make sure an internal safety containment cable is included in case of breakage. Springs tend to be the first part of the garage door to need service or replacement. Many springs are tested to operate between 5,000 to 10,000 cycles while some manufacturers make a spring that will last up to 30,000 cycles or more. That s a wide difference in longevity and value when you add it up. Most homeowners use their garage doors up to 3,000 times per-year so a 10,000-cycle spring could break within 3-4 years. Replacement usually costs $150 - $250. Check the manufacturer s warranty on the spring. Never buy a door with only a one-year warranty on the spring.
