When Should You Replace Your Garage Door Springs?

Most homeowners don’t think about their garage door springs until something goes wrong. But springs don’t last forever — and knowing when to replace them can save you from being stuck in the garage with a broken door and a car you can’t get out.

How Long Do Garage Door Springs Last?

Standard garage door springs are rated for approximately 10,000 cycles. One cycle equals one full open and close. For a household that uses the garage door 4 times a day, that works out to roughly 7 years. Use it more and the springs wear out faster. Live near the coast where salt air corrodes metal? Springs may fail sooner than that estimate suggests.

The 8,000–10,000 Cycle Zone Is When Springs Break

Between 8,000 and 10,000 cycles, your springs are in the high-risk zone. Most spring failures happen in this range — not always at exactly 10,000. Springs don’t give you a warning light. A spring that breaks at 9,200 cycles leaves your car stuck in the garage just the same as one that reaches 10,000. The 8,000-cycle mark is when Castle recommends replacing your springs — not waiting for the failure.

Signs Your Springs May Be Getting Close

• Door feels heavier than usual when lifting manually
• Opener strains, slows down, or sounds different than it used to
• Door doesn’t open all the way, or reverses unexpectedly
• Springs look stretched out, rusty, or have a slight gap forming
• It’s been 7+ years since your last spring replacement
• You use your garage door frequently (more than 4 times a day)

The Coastal Factor

Homes in Carlsbad, Encinitas, Oceanside, La Jolla, Del Mar, and other coastal communities face an additional risk: salt air and marine moisture accelerate corrosion on springs, cables, and metal hardware. Springs in these areas may wear out faster than the typical 7–10 year estimate. If you live within a few miles of the coast, the 8,000-cycle warning zone applies even sooner.

Do You Know How Many Cycles Your Springs Have?

Most homeowners don’t — and that’s normal. If you know how long you’ve had your current springs and roughly how often you use your garage, you can estimate it. Use our Garage Door Spring Cycle Calculator to estimate where your springs stand. If you have a MyQ-enabled LiftMaster or Chamberlain opener, there may be another way to check — the MyQ app’s diagnostics feature can show door cycle data on select openers.

Why You Shouldn’t Wait for the Spring to Break

When a spring breaks, the door typically becomes inoperable — the opener can’t lift the full door weight and will usually just click or move the door a few inches before stopping. In many cases, the vehicle inside the garage is stuck until a technician arrives. Replacing springs proactively before failure is almost always more convenient, and avoids the urgency and stress of an emergency call.

There’s another reason not to wait: some doors use custom spring sizes that aren’t stocked on the truck and have to be ordered from the manufacturer. That can mean a few days without a working garage door while you wait for parts to arrive. When you schedule a replacement proactively, there’s no pressure — you can pick a time that works and avoid the gap entirely. When a spring breaks unexpectedly, you don’t have that option.

What Happens During a Spring Replacement?

A Castle technician will inspect both springs (most doors have two), measure the door, and install the correct replacement springs. We always recommend replacing both springs at the same time — if one has worn out, the other is close behind. Most standard springs are carried on the truck and the job is done in under 90 minutes. If your door requires a custom spring size, we’ll let you know upfront so you can plan around the lead time rather than being caught off guard.
