Are your technicians licensed and insured?

Should I repair or replace my garage door?
A good rule of thumb: if the repair costs more than about 50% of a replacement, or the garage door is near the end of its life, replace it. A garage door typically lasts 15 to 30 years. If several panels are damaged, the door is rusted through or rotted, or parts are discontinued, replacing it is often better value. Springs are the exception: a broken spring is always replaced, never repaired. Our free repair vs. replace calculator can help you compare.
