Is Cornell Cookson rolling steel door repair covered by a warranty?

Are your technicians licensed and insured?

Should I repair or replace my commercial door?
A good rule of thumb: if the repair costs more than about 50% of a replacement, or the commercial door is near the end of its life, replace it. Commercial doors are rated by cycles. If the door has reached its rated cycle life, has several damaged sections, or parts are no longer made, replacing it is often cheaper over the next few years. Springs are the exception: a broken spring is always replaced, never repaired. Our free repair vs. replace calculator can help you compare.
