Is Cornell Cookson rolling fire door inspection & drop testing covered by a warranty?

Our work comes with a 90-day labor warranty on repairs. New parts and doors also carry the manufacturer's warranty, and Cornell Cookson warranty terms vary by product and age. Ask for the warranty details in writing with your quote.

Are your technicians licensed and insured?

Our technicians are insured, and where Colorado or Thornton requires a contractor license for garage door work, the job is done under that license. You're welcome to ask for proof when you book.

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.
