Overhead Door Extension Spring Replacement is one of the most common calls we get. A technician will explain what is wrong and what it will cost before starting, and test the door before leaving. Side-mounted extension springs replaced in matched pairs, with safety cables installed. Our technicians service Overhead Door garage doors regularly and know where the model and date labels are, which makes ordering the right part quicker. Overhead Door traces its roots to C.G. Johnson, who invented the upward-acting garage door in 1921. The company builds residential and commercial doors and openers.
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.
Signs you need Overhead Door extension spring replacement
- A stretched, sagging or snapped spring along one of the horizontal tracks
- The door lifts unevenly or sits crooked
- A missing or broken safety cable through the spring
- Pulleys squealing or wobbling
Common causes
- Metal fatigue from years of stretching
- Rust and worn pulleys
- Mismatched springs from an earlier repair
Safe checks before you call

Overhead Door Extension Spring Replacement in Lilburn, GA
Humidity in Georgia puts a thin layer of rust on spring coils, and that friction wears springs out early. Coated or galvanized springs last noticeably longer here.
Close to the coast, salt air speeds up corrosion. Galvanized or coated springs, nylon rollers and stainless hardware hold up better than bare steel.

Overhead Door Extension Spring Replacement: frequently asked questions
How much does Overhead Door extension spring replacement cost in Lilburn, GA?
Overhead Door 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 Overhead Door 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 Overhead Door 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 Overhead Door 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 Georgia or Lilburn 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.
