Most people don't think about their garage door until something breaks. That's when the spring fails, the door won't budge, and suddenly you're stuck. Garage door springs in Mountlake Terrace are the hardest working part of your system, and when they snap, you need a technician fast. Here's what you need to know about springs, why they fail, and how much you'll actually spend to fix them.
Your garage door weighs between 300 and 400 pounds. Without springs, you couldn't open it by hand. Torsion springs are the most common type in residential garages. They're mounted horizontally above the door opening and use stored energy to counterbalance the weight. When you open the door, springs unwind. When you close it, they wind back up. This happens thousands of times over the spring's lifetime.
Extension springs work differently. They run along the sides of the door and stretch when the door opens. Both types eventually wear out because metal fatigues. Springs last between 7 and 9 years under normal use, sometimes longer if you're lucky. That's roughly 10,000 to 15,000 cycles before they fail.
A snapped spring won't just inconvenience you. It can damage your opener, bend the door, or worse. Watch for these warning signs:
The door opens only partway before stopping. Your opener runs but the door won't move. You hear a loud bang or crack from the garage. The door feels heavier than usual when you try to open it manually. There's visible rust or corrosion on the springs themselves.
If you notice any of these, don't keep using the door. Call us for an estimate. A failing spring puts extra strain on your entire system and can cause a cascade of repairs.
Sometimes a spring snaps without warning. If that happens, you're locked out and the door is immovable. That's when same-day repair matters.

Spring replacement cost varies based on spring type, door size, and whether one or both springs need replacing. A single torsion spring typically runs between $200 and $400 in labor and parts. If both springs are worn, expect closer to $400 to $600 total. Extension springs cost slightly less, around $150 to $300 per spring.
These prices include the spring itself and professional installation. We always recommend replacing both springs at the same time, even if only one is broken. When one spring fails, the other is usually close behind. Replacing one now and the other in six months doubles your service costs and creates two separate emergencies.
Don't attempt this yourself. Garage door springs are under extreme tension. A snapped spring can cause serious injury. We've seen DIY attempts go wrong more times than I can count in 15 years on the trucks. Let a professional handle it safely.

You can't prevent springs from aging, but you can slow the process. Keep the door balanced by testing it monthly. Close the door, then pull the emergency cord and try to raise it manually. A balanced door should open smoothly with light pressure. If it's heavy on one side, springs are wearing unevenly.
Lubricate the springs twice a year with a silicone-based garage door lubricant. This reduces friction and extends life. Avoid using WD-40 or general purpose oils. They attract dust and can gum up the mechanism.
Finally, avoid opening and closing the door excessively. Every cycle counts against the spring's lifespan. If you have frequent deliveries or contractors coming in, you'll wear springs faster than a homeowner who uses the door once or twice daily.

How do I know if my garage door spring is broken? The door won't open or opens only halfway. You hear a loud bang or crack. The door feels much heavier when you try lifting it manually. Never ignore these signs. A broken spring affects your entire system.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if they snap during DIY installation. Always hire a licensed technician. The small cost savings isn't worth the risk.
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal residential use. This equals roughly 10,000 to 15,000 open-close cycles. Climate and usage frequency affect lifespan.
Should I replace both springs if only one is broken? Yes. When one spring fails, the other is usually wearing out too. Replacing both at once saves money and prevents a second emergency repair within months.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist to provide lift. Extension springs run along the sides and stretch. Torsion springs are more durable and common in residential garages.
