Your garage door relies on springs to lift a structure that weighs 300 to 500 pounds. Most people don't think about how those springs work until something breaks. Understanding the difference between torsion and extension springs helps you know what to expect when repair time comes and why proper installation matters.
A garage door spring system does almost all the heavy lifting. Your opener provides just 10 percent of the effort needed to raise the door. The springs handle the rest, storing and releasing tension thousands of times over their lifespan. This is why a snapped spring feels like a complete failure, even though the door itself may be fine.
Two main spring types exist in residential garage doors: torsion springs and extension springs. Each design carries weight differently and has distinct safety implications. Hillsboro homes use both types depending on door age, frame design, and installation choices.
Torsion springs mount horizontally above your garage door opening. As the door closes, these springs wind up like a clock spring, storing mechanical energy. When the opener pulls the door upward, that stored energy releases gradually, making the lift smooth and controlled.
Most newer installations in the Hillsboro area use torsion springs. They're more durable, quieter, and safer than their extension counterparts. A quality torsion spring lasts 7 to 9 years with normal use. When one fails, the door becomes nearly impossible to open manually because all that weight support vanishes instantly.
Torsion springs require precise installation. The spring must be wound to exact tension for your specific door weight. This is why DIY replacement creates real danger. A wound spring under that much tension can cause serious injury if it slips.
Extension springs run vertically along both sides of your garage door opening. As the door lowers, these springs stretch. As it rises, they contract, pulling the cables that help lift the door. Older homes and some budget installations use extension springs because they cost less upfront.
Extension springs also last 7 to 9 years typically. When one snaps, you'll hear a loud bang and the door will tilt toward the broken side as it tries to open. This imbalance stresses your opener and the remaining spring, accelerating failure of the good spring.
Safety cables run through extension springs for this exact reason. If a spring snaps while the door is open, the cable catches it and prevents the door from crashing down. Still, extension spring failure is more dramatic and disruptive than torsion spring problems.

Look above your garage door from inside the garage. If you see a horizontal metal shaft with a spring coiled around it, you have torsion springs. If you see two springs running vertically on each side of the opening, those are extension springs. This simple check tells you exactly what you're working with.
Some doors use both types in hybrid setups, though this is less common. Your door's design, age, and weight class determine which system works best. When replacement time comes, we can schedule a free quote to review your specific setup and discuss your options.
Torsion springs typically cost more to replace than extension springs because installation requires special tools and expertise. An extension spring replacement may run $150 to $300 per spring. Torsion spring work usually falls between $200 and $400 per spring depending on your door's weight class.
The total cost matters, but so does getting the job right. Improper spring installation leads to premature failure, opener strain, and safety hazards.

Spring work isn't a good DIY project. We've written extensively about why snapped spring repair demands professional help, and that applies equally to planned replacements. The tension stored in a compressed torsion spring or stretched extension springs can cause serious injury if something goes wrong.
Professional technicians use specialized winding bars, calibrated tools, and safety protocols. We also balance your door after installation to ensure smooth operation and even weight distribution.
Your garage door springs deserve the same respect and attention you'd give to any structural component of your home. Get it done right the first time.

How long do garage door springs last? Quality torsion and extension springs typically last 7 to 9 years with normal residential use. Factors like climate, door use frequency, and maintenance affect lifespan. Springs in garages that open and close multiple times daily wear faster than seasonal-use doors.
Can I replace just one spring if only one breaks? We recommend replacing both springs even if only one has failed. Springs degrade together over time. The remaining spring is likely close to failure, and replacing just one creates imbalance and accelerates failure of the good spring.
What's the difference in safety between torsion and extension springs? Torsion springs fail gradually as they lose tension. Extension springs snap suddenly with loud noise and dramatic door tilt. Extension springs include safety cables to catch the door if they break. Both types require professional installation and handling.
How much does spring replacement cost near me? Spring replacement costs in Hillsboro range from $300 to $800 total depending on spring type, door weight, and whether you need one or both springs replaced. We provide a free estimate before any work begins, so you know the exact cost upfront.
