Cornell Cookson Rolling Fire Door Inspection & Drop Testing: frequently asked questions
How much does Cornell Cookson rolling fire door inspection & drop testing cost in Colorado?
Cornell Cookson Rolling Fire Door Inspection & Drop Testing typically costs $150-$500 including parts and labor, and usually takes about 1 hour per door. The exact price depends on your door and the parts it needs, and you get it before any work starts. Call (833) 435-8883 for a quote.
Can you do Cornell Cookson rolling fire door inspection & drop testing the same day?
Often, yes. When a technician is available we can usually come the same day, and common parts are carried on the truck. Doors that won't close or have a broken spring are treated as priority calls, and emergency service is available.
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 your city 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.
