Most homeowners in Lexington think the opener is what lifts their garage door. It isn't. The opener is just a motor. The real work is done by the torsion or extension springs mounted above and alongside your door. they counterbalance hundreds of pounds of door weight so the opener barely has to strain. When those springs are healthy, everything feels effortless. When they start to fail, things get expensive fast.
The good news is that springs rarely fail without warning. There's usually a window. days or weeks. where the signs are visible if you know what to look for. Catching a spring before it breaks is the difference between a straightforward replacement visit and an emergency call with a door stuck halfway up while you're trying to leave for work.
This is especially relevant in Lexington, where the combination of cold winters and humid summers accelerates wear on metal components. Homes in neighborhoods like Follen Heights or the Five Fields area often have two-car garages that see heavy daily use. multiple cycles morning and evening, every day. That adds up faster than most homeowners realize.
Most standard torsion springs are rated for around 10,000 cycles. one cycle being one full open and one full close. If your household opens the garage four times a day, that's roughly 7 to 9 years of life. Heavier doors, like the solid wood carriage-style doors common on some of Lexington's larger Colonials, wear springs faster. High-cycle springs rated for 25,000+ cycles are available and worth the upgrade if you have heavy daily use.
If you bought your home and have no idea when the springs were last replaced, assume they may be due. Springs don't come with a sticker. Check with the previous owners or just ask a technician to assess them during a service call. it's a quick inspection.
Disconnect your opener by pulling the red emergency release cord, then try to lift the door manually to about waist height. A properly balanced door should feel light. almost floating. and should stay in place when you let go at any point in its travel. If it feels heavy, drops when released, or you're straining to lift it, the springs are either worn out or broken. This is the single most reliable field test you can do yourself.
One of the most startling signs of a broken spring is a sound many homeowners describe as a gunshot or a firecracker going off in the garage. That's the spring releasing its stored tension all at once when it snaps. If you hear this. even if it's 2 a.m. don't attempt to operate the door. The spring has failed. Trying to run the opener with a broken spring can destroy the opener motor in seconds.
Torsion springs sit horizontally above your garage door opening. Take a moment to look up at them when the door is closed. A healthy spring is a continuous, tight coil with no interruptions. If you see a gap. a space where the coils have separated. the spring has snapped at that point. This is an unambiguous sign of failure. Do not operate the door.
Most residential garage doors have two springs, one on each side of the torsion bar. When one spring fails while the other still works, the door lifts unevenly. one side rises faster or higher than the other, causing a tilting or twisting motion. This uneven strain quickly damages the cables, the tracks, and the opener itself. If your door looks crooked when moving, stop using it and get it inspected.
Lexington's climate. with its wet springs, humid summers topping 70% humidity in August, and heavy snowfall. creates ideal conditions for rust. A rusty spring is a weakened spring: the corrosion creates micro-fractures in the metal that make it far more likely to snap. If you see orange discoloration or surface rust on your springs, don't wait for them to break. This is a proactive replacement situation. Understanding repair costs ahead of time can help. see our repair cost breakdown for what to expect.
Some noise when a door operates is normal. But if you're hearing new squeaking, grinding, or if the opener sounds like it's working harder than usual, pay attention. These sounds often mean the springs are no longer adequately counterbalancing the door's weight, forcing the opener motor to compensate. Over time this kills the opener. A spring replacement is far cheaper than replacing both the spring and the opener.
If one spring on a two-spring system breaks, most technicians will recommend replacing both at the same time. The logic is straightforward: if one spring has reached the end of its life, the other is likely close behind. Replacing both ensures even tension, balanced door movement, and means you won't be calling again in six months for the second one. It's more cost-efficient in the long run.
This also applies to homeowners in nearby communities like Concord or Winchester who have older homes. matching spring age and tension is critical to balanced operation.
This deserves to be stated plainly: garage door spring replacement is not a homeowner project. Torsion springs are wound under hundreds of pounds of tension. When that energy releases unexpectedly. because of a wrong move, a slipping tool, or an improperly secured bar. the consequences can be severe. Professional technicians use specialized winding bars, safety cables, and know exactly how many turns each spring requires based on door weight and height. Getting this wrong doesn't just mean a broken door. it can mean a serious injury.
If you see any of the signs above, the right call is to stop operating the door and contact a professional. Lexington Garage Doors can typically get to most Lexington locations same-day or next-day for spring failures. Our service area page has full coverage details.
You can extend spring life meaningfully with simple maintenance. Apply a silicone-based lubricant to the springs every three months. a light coat along the coils, not soaking them. Wipe away any dust or debris buildup around the springs and surrounding hardware during each seasonal inspection. And while you're at it, test your door's balance using the manual lift method described above. Catching tension loss early gives you the option to schedule a replacement on your terms rather than in the middle of a February snowstorm.

Q: How do I know if my garage door has torsion springs or extension springs? A: Look above the door when it's closed. If you see a single long spring (or two springs) mounted horizontally along a metal bar above the opening, those are torsion springs. the most common type in homes built in the last 30 years. If you see springs running along the horizontal tracks on each side of the door, those are extension springs. Both types wear out and both require professional replacement.
Q: My opener is still running but the door barely moves. Is that the spring? A: Almost certainly, yes. When a spring breaks, the opener is suddenly trying to lift the full weight of the door. 150 to 300 pounds. without any help. Most modern openers have a built-in force limit and will stop rather than burn out, but they're still under serious strain. Stop pressing the button and call for service. Continued attempts will damage the opener.
Q: How much does a spring replacement typically cost in the Lexington area? A: Costs vary depending on the type of spring, door size, and whether you're replacing one or two. Contact us for an accurate quote. we're straightforward about pricing and won't recommend parts you don't need.
