Our commercial garage door repair service in Dover, NH comes down to three things: a clear diagnosis, the right parts on the truck, and a door that is balanced and safety-tested when we finish. Repairs for commercial sectional, overhead and service doors.
Safety first: springs and cables hold hundreds of pounds of tension. Don't try to adjust or remove them yourself, and don't run the opener on a door that's crooked or has a broken spring.

Local commercial garage door repair for Dover, NH
Road salt and meltwater dripping off vehicles rust the bottom of tracks, cables and roller stems, which is why cable and roller failures in New Hampshire usually start at floor level.
Close to the coast, salt air speeds up corrosion. Galvanized or coated springs, nylon rollers and stainless hardware hold up better than bare steel.

Commercial Garage Door Repair: frequently asked questions
How much does commercial garage door repair cost in Dover, NH?
Commercial Garage Door Repair typically costs $250-$1,000 including parts and labor, and usually takes 1-4 hours. 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 commercial garage door repair 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 commercial garage door repair 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. Ask for the warranty details in writing with your quote.
Are your technicians licensed and insured?
Our technicians are insured, and where New Hampshire or Dover 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.
