From the first phone call to the final safety test, Martin Door extension spring replacement in your area follows a simple process: diagnose, quote, repair, test. Side-mounted extension springs replaced in matched pairs, with safety cables installed. We work on Martin Door garage doors of every age, from older models to current lines, and carry or can source compatible parts.
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 Martin 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
Why this happens
- Metal fatigue from years of stretching
- Rust and worn pulleys
- Mismatched springs from an earlier repair
Safe checks before you call
- Make sure each extension spring has a safety cable running through it. That cable keeps a snapped spring from flying across the garage.
- Look at the pulleys and cables for fraying.
- Don't try to stretch or re-hook an extension spring under tension.
Still stuck? Our free symptom checker and troubleshooting wizard walk you through it step by step.

Martin Door Extension Spring Replacement: frequently asked questions
How much does Martin Door extension spring replacement cost?
Martin 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 Martin 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 Martin 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 Martin 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 your state or 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 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.
