When a garage door spring breaks, homeowners often consider tackling the replacement themselves. After all, how hard can it be? The answer: extremely hard.and potentially deadly. Garage door spring replacement is one of the most dangerous home repair tasks, and there are compelling reasons why it should always be left to trained professionals.
Before discussing the dangers, it's important to understand how garage door springs work. There are two main types:
Torsion Springs Located above the door, torsion springs twist to store energy when the door closes. This stored energy then helps lift the heavy door when you open it. A typical residential torsion spring is wound under 150-300 inch-pounds of torque.enough force to cause serious injury or death if released suddenly.
Extension Springs These springs stretch along the sides of the door and extend when the door closes. While perhaps slightly less dangerous than torsion springs, they're still under significant tension and can cause severe injuries if they break or are mishandled.
Every year, DIY garage door spring replacement leads to emergency room visits and, tragically, fatalities. Here's what makes this job so dangerous:
Extreme Tension The springs on a garage door counterbalance a door that can weigh 150-400 pounds or more. That weight is translated into spring tension. When a spring is wound (torsion) or stretched (extension), it stores an enormous amount of potential energy. Releasing that energy suddenly.which can happen if you make a mistake.can send tools flying, cause the spring to whip violently, or cause the winding bar to slip and strike you.
Specialized Tools Required Proper spring replacement requires specialized winding bars and other tools. Using improvised tools like screwdrivers or regular bars significantly increases the risk of injury. The right tools fit precisely and are designed to handle the forces involved.
Precise Technique Needed Spring replacement isn't just about removing the old spring and installing a new one. The spring must be wound to precisely the right tension.too little and the door won't stay up; too much and you risk damaging the door or opener. Professionals know exactly how many turns are needed based on the door's size, weight, and spring specifications.
Risk of Sudden Release One of the most dangerous moments is when the spring is fully wound and you need to set the tension. If the winding bar slips, the spring can unwind violently, potentially fracturing bones, causing severe lacerations, or worse.
As garage door professionals, we've seen firsthand what can happen when DIY spring replacement goes wrong:
- A homeowner in Torrance was struck in the face when a winding bar slipped, resulting in a broken cheekbone and lost teeth. - A Redondo Beach resident suffered a spiral fracture of the forearm when a torsion spring suddenly unwound. - We've replaced doors damaged when improperly tensioned springs caused the door to crash down unexpectedly.
These aren't isolated incidents.they happen regularly across the country.
Some homeowners attempt DIY spring replacement to save money, but let's look at the real costs:
DIY Approach - Springs: $30-100, Tools (if purchased): $50-100, Risk of injury: Priceless (not in a good way) - Risk of damaging door or opener: Hundreds to thousands in repairs, Time: Several hours if you're inexperienced
Professional Replacement - Total cost including parts and labor: $150-350 typically, Risk of injury: Minimal (professionals have training and insurance) - Risk of damage: Covered by company if it occurs, Time: Usually under an hour
When you factor in the risks and potential additional costs, professional spring replacement is almost always the smarter choice.
If your garage door spring breaks, here's the right approach:
1. Don't try to operate the door. Without functioning springs, the door is much heavier and the opener will strain or fail trying to lift it.
2. If the door is stuck open, disconnect the opener and carefully lower the door manually if possible. Be aware that it will be very heavy.
3. Call a professional. Most garage door companies, including ours, offer same-day service for spring replacement. We stock common spring sizes and can usually complete the repair in a single visit.
4. Don't be tempted to order springs online and do it yourself. The money you save isn't worth the risk.
