In our Experienced Local Team Westport, we've seen this problem again and again: a homeowner wakes up, hits the opener button, and nothing happens. The door won't budge. Nine times out of ten, it's a snapped garage door spring. Springs are the hardest working part of your system, and when they fail, your door becomes a 400-pound paperweight. This guide covers what you need to know about garage door springs in Westport and when to call for help.
Garage door springs are under constant tension. A single torsion spring can hold up to 200 pounds of force, and it cycles thousands of times per year. Over time, metal fatigues. Most residential springs last 7 to 9 years with normal use, not longer.
Westport winters accelerate the process. Cold temperatures make metal brittle. Salt air corrodes the coils. Temperature swings cause expansion and contraction that weakens the metal from the inside. If your spring was installed 8 or more years ago, failure isn't a question of if but when.
Extension springs (the type that run along the sides of the door) tend to fail faster than torsion springs because they take more direct stress. Both types will eventually snap, and when they do, the door drops hard and fast.
Torsion springs mount horizontally above the door opening. They're the workhorses. One snapped torsion spring can stop the whole system, even if you have two springs installed. They're expensive to replace but last longer.
Extension springs run vertically along each track. They're cheaper to install but wear out sooner, especially in our salt-heavy climate. You'll often find two of them working together, which means one failure puts extra load on the other.

A loud bang or crack from the garage is the classic warning. Sometimes you'll hear a sound like a gunshot. That's the spring breaking.
Before it breaks completely, watch for these red flags: the door moves slowly or jerks when opening, the door closes too fast (springs losing tension), or the door sits slightly off-balance even when closed. If you see the door sagging on one side, a spring on that side is weakening.
Never try to open a door with a broken spring manually. The tension release is violent and unpredictable. A snapped spring can cause serious injury.
Our garage door maintenance guide for Westport covers routine inspections that catch spring wear before it becomes an emergency. A technician can spot wear patterns and recommend replacement before failure.
Spring replacement isn't cheap, but it's non-negotiable. A single torsion spring replacement runs between $200 and $400 in parts and labor, depending on the spring type and door weight. If you have two torsion springs and both are original equipment, expect them both to fail within a year of each other. Replace both at once. The cost per spring drops slightly when doing a pair.
Extension springs are cheaper, usually $100 to $200 per spring installed, but again, replace them in pairs so you don't overload the remaining spring.
Labor is the bigger chunk of that cost. Spring replacement requires specialized tools and training. It's a two-person job at minimum. For a detailed breakdown of what you're paying for, check our honest garage door cost and pricing guide for Westport.
Garage Door Westport handles spring replacement as part of our full repair and maintenance services. We stock common spring sizes and can often provide same-day service for snapped springs. We'll inspect the rest of your door while we're there. Rollers, cables, and the opener itself can wear out at the same time as springs. A complete inspection catches problems before they strand you.
Schedule a free quote for spring replacement and we'll assess whether both springs need replacing or if one will hold a while longer.
You can't prevent springs from wearing out, but you can slow it down. Regular lubrication reduces friction and heat buildup. Keeping your garage reasonably climate-controlled during winter helps too. Our lubrication and inspection guide walks through what homeowners can do between service calls.
Most importantly, don't ignore warning signs. A slow-moving door or uneven opening isn't a minor annoyance. It's your spring telling you it's near the end. Call us before it breaks, and you'll avoid the emergency service markup.
Spring failure happens fast and without warning. If your door is struggling or you hear noise, contact Garage Door Westport now. We serve all of Westport and the surrounding areas with same-day estimates and quick turnaround.

How long do garage door springs last? Most torsion springs last 7 to 9 years under normal residential use. Westport's salt air and winter cold can shorten that to 5 to 7 years. Extension springs typically fail sooner, often within 5 to 8 years. Cycle count matters more than calendar years.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and training. The tension is dangerous. Improper installation can cause injury or damage to the opener and door. Always hire a professional technician to handle spring work.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and use rotational force. Extension springs stretch along the door tracks. Torsion springs last longer and handle heavier doors better, but cost more. Extension springs are cheaper but wear faster.
Do both springs need replacing at the same time? If one torsion spring fails, replace both. The second spring is near the end of its life too, and you'll avoid a second failure weeks later. For extension springs, replacing the pair prevents overload on the remaining spring.
Is spring replacement covered by warranty? Most warranties cover defects within the first year, not normal wear. Springs are wear items. Some service plans include spring replacement as part of annual maintenance. Ask about coverage when you call for an estimate.
