Serving Fallston, MD and nearby towns
The swing from hot, humid summers to freezing winters in Maryland is hard on spring steel. Rust shortens spring life, and the first cold snap is when a worn spring tends to break.
Close to the coast, salt air speeds up corrosion. Galvanized or coated springs, nylon rollers and stainless hardware hold up better than bare steel.

CHI Overhead Doors Extension Spring Replacement: frequently asked questions
How much does CHI Overhead Doors extension spring replacement cost in Fallston, MD?
CHI Overhead Doors Extension Spring Replacement typically costs $150-$350 including parts and labor, and usually takes 1-1.5 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 CHI Overhead Doors extension spring 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 CHI Overhead Doors extension spring 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 CHI Overhead Doors 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 Fallston 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 garage door?
A good rule of thumb: if the repair costs more than about 50% of a replacement, or the garage door is near the end of its life, replace it. A garage door typically lasts 15 to 30 years. If several panels are damaged, the door is rusted through or rotted, or parts are discontinued, replacing it 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.
