Deciding whether to repair or replace your garage door depends on the extent of the damage and the age of the door. Replacement may be more cost-effective if the door is over 15 years old or has significant damage (like warped panels or broken hardware). However, minor issues like a broken spring, misaligned track, or worn rollers can typically be repaired. 

An insulated garage door helps regulate the temperature inside your garage, making it more comfortable year-round. This is especially helpful if you use your garage as a workspace or living space. Insulation also improves energy efficiency, reduces noise, and protects your belongings from extreme weather.
