Your garage door relies on springs to lift roughly 300 to 400 pounds with minimal effort from the opener. Two main types exist: torsion springs and extension springs. Torsion springs sit above the door and twist to store energy, while extension springs run horizontally along each side and stretch. Understanding which one your door uses saves money on repairs and prevents costly mistakes down the line.
Torsion springs are the standard in most modern homes, including properties across Dracut and the surrounding North Shore area. These cylindrical coils mount on a metal shaft directly above your garage door opening. When the door closes, the springs wind tighter, storing mechanical energy. When you open the door, that energy releases and helps lift the weight.
One major advantage: torsion springs last longer than their extension counterparts. You can expect seven to nine years of reliable service before replacement becomes necessary. They also fail more safely. When a torsion spring snaps, the door typically stays in place rather than crashing down unexpectedly.
The trade-off is upfront cost. Torsion springs run higher in price than extension springs, but the durability and safety profile justify the investment for most homeowners.
Extension springs work differently. They hang vertically on each side of the door frame and stretch as the door opens. When the door closes, they contract and help pull it down. Older homes and some lighter-duty doors use this design.
Extension springs are cheaper upfront, which explains their appeal. However, they wear faster and present a safety concern. When an extension spring snaps, the door can fall suddenly. Safety cables run alongside these springs to catch the door if failure occurs, but the risk remains higher than with torsion systems.

Look above your garage door. If you see a single horizontal shaft with coils wound around it, you have torsion springs. If you see springs hanging on both sides of the door frame that stretch vertically, you have extension springs.
Don't attempt to inspect closely or touch the springs themselves. Springs under tension can cause serious injury or death if they snap during inspection. Always call a professional to diagnose and repair spring problems.

Torsion spring replacement typically costs $200 to $400 per spring, depending on the quality and size of your door. Extension springs run $75 to $200 per spring. Labor costs remain similar for both types, usually $150 to $300 per service visit in the Dracut region.
If you have a snapped spring and need quick repair, same-day availability matters more than the few dollars you might save by choosing the cheaper option. A broken spring leaves your door inoperable or unsafe, affecting your daily routine and home security.
Springs fail due to normal wear, rust, and metal fatigue. Dracut's humid New England climate accelerates corrosion on steel springs. Poor lubrication also shortens spring life. Regular maintenance, including light lubrication every few months, can extend the years you get from your springs.
Check our maintenance guide for simple steps that protect your entire system.
Never attempt a DIY spring repair. The tension in these components is extreme, and improper handling causes injury. Professional technicians have tools and training to safely handle spring issues.
When springs fail, replacement is almost always the correct choice. Repair isn't practical, and attempting temporary fixes creates safety hazards. Schedule a free quote with Dracut Garage Doors to get an accurate estimate for your specific door type and spring system.
Your garage door's spring type affects cost, safety, and longevity. Torsion springs offer better durability and safer failure characteristics, while extension springs cost less upfront but wear faster. Whichever type you have, professional inspection and maintenance extend its lifespan and protect your investment.
Don't wait for a spring to snap unexpectedly. If your door is more than seven years old, have the springs inspected now. Call (978) 723-4600 or contact us online to arrange a same-day estimate and avoid the emergency service premium that catches most homeowners off guard.
What does a snapped spring sound like? A loud bang or crack, similar to a gunshot, indicates spring failure. The door may stop mid-travel or feel heavier than normal. Stop using the door immediately and call a professional.
Can I replace one spring if only one snaps? No. Springs wear in pairs. Replacing one while leaving an older, weaker spring on the other side creates imbalance and causes premature failure of the remaining spring. Replace both for even operation and safety.
How often should springs be lubricated? Every three to four months. Use a silicone-based garage door lubricant, not WD-40. Light, regular lubrication reduces rust and friction, extending spring life by one to two years.
Are extension springs safer than torsion springs? Torsion springs are safer. They fail more slowly and keep the door from crashing if failure occurs. Extension springs can snap suddenly, though safety cables provide some protection.
What's the typical lifespan of garage door springs? Torsion springs typically last seven to nine years with normal use and maintenance. Extension springs often fail after five to seven years. Climate, humidity, and lubrication affect actual lifespan.
