From the first phone call to the final safety test, Sommer opener gear & sprocket replacement in Ashton-Sandy Spring, MD follows a simple process: diagnose, quote, repair, test. Stripped drive gears replaced so the motor moves the door again. Whether your Sommer opener is a few years old or a few decades, we can diagnose it and tell you honestly whether it is worth repairing. Sommer openers, made in Germany, put the motor on a carriage that travels along the rail instead of hanging from the ceiling, so servicing them is a little different from a conventional opener.

Sommer Opener Gear & Sprocket Replacement: frequently asked questions
How much does Sommer opener gear & sprocket replacement cost in Ashton-Sandy Spring, MD?

Can you do Sommer opener gear & sprocket replacement 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 Sommer opener gear & sprocket replacement 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 Sommer 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 Maryland or Ashton-Sandy Spring 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 opener?
A good rule of thumb: if the repair costs more than about 50% of a replacement, or the opener is near the end of its life, replace it. Most openers last 10 to 15 years. If yours is older than that, lacks photo eyes or rolling-code security, or needs a logic board or motor, a new opener 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.
