When your door needs Northwest Door extension spring replacement, you want it done safely and right the first time. Typical jobs in your area cost $150-$350, and you approve the price first. Side-mounted extension springs replaced in matched pairs, with safety cables installed. Whether your Northwest Door garage door is a few years old or a few decades, we can diagnose it and tell you honestly whether it is worth repairing.
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.
Is it time for Northwest Door extension spring replacement?
- A stretched, sagging or snapped spring along one of the horizontal tracks

Why this happens
- Metal fatigue from years of stretching
- Rust and worn pulleys

Northwest Door Extension Spring Replacement: frequently asked questions
How much does Northwest Door extension spring replacement cost?
Northwest 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 Northwest 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 Northwest 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 Northwest 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.
