Garage Door Spring Replacement in Haverhill: What Homeowners Need to Know
2026-04-05 6 min read
There's a sound Haverhill homeowners dread. a sharp, sudden bang from inside the garage that rattles the walls. Nine times out of ten, that's a garage door spring letting go. One moment everything works fine; the next, the door won't open, or it opens a few inches and stops. It's one of the most disruptive garage door failures you can experience, and it almost always comes without much warning.
The good news is that springs do show signs of wear before they snap completely. Knowing what to look for. and understanding how Haverhill's climate accelerates spring wear. can help you get ahead of this repair instead of dealing with it as an emergency.
How Garage Door Springs Actually Work
Garage door springs counterbalance the weight of your door, making a 150,300 lb panel manageable for a small electric opener motor. Without functioning springs, the opener is trying to lift the full dead weight of the door. something it was never designed to do. There are two main types:
Torsion springs mount horizontally above the door opening and twist to store and release energy. They're more durable, found in most modern installations in the area, and typically rated for 10,000 to 20,000 cycles. Extension springs run along the horizontal tracks on either side and stretch under tension. They're more common in older homes. and Haverhill has plenty of those, given that the town was founded in 1763 and its housing stock reflects well over two centuries of building history.
The average garage door opens and closes about 1,500 times per year. That math means even a quality spring has a finite lifespan, and that lifespan gets shorter here in the Upper Connecticut River Valley where extreme cold makes metal more brittle every winter.
Warning Signs Your Springs Are Failing
Don't wait for the loud bang. These are the signs that should prompt a call or inspection:
The Door Feels Unusually Heavy
Disconnect your opener and try lifting the door manually to about waist height. A properly balanced door should stay right where you leave it. If it falls back down immediately or feels like you're lifting dead weight, the springs are no longer doing their job. This is often one of the first signs of trouble. and one most homeowners miss because they rely on the opener and never test the door by hand.
Uneven or Lopsided Movement
If your door tilts to one side as it opens, sagging lower on one end, that's a strong signal that one spring has failed while the other is still functioning. On a two-spring torsion system, when one spring breaks, the remaining spring can't evenly distribute the door's weight. The door lifts crookedly, which strains cables, rollers, and the opener.
The Opener Strains, Hums, or Stops Mid-Lift
If your automatic opener seems to struggle, makes unusual noises, or stops before the door is fully open, it's likely compensating for a broken or weak spring. The opener is not designed to handle the door's full weight, and continued use in this condition can burn out the motor or strip the drive gears. turning a spring replacement into a much more expensive job.
A Visible Gap in the Spring Coil
For torsion springs, look above the door at the horizontal shaft. A gap of about two inches or more in the coil means the spring has snapped. The coil should be uniform and continuous. If it isn't, the spring is broken. stop using the door immediately and don't attempt to open it manually.
Rust or Visible Corrosion
Over time, exposure to moisture causes springs to rust, which weakens the metal and shortens their lifespan. In Haverhill, with January and February humidity averaging 87% and snowfall months stretching from October through May, moisture exposure is a year-round reality. A rusty spring is more brittle and prone to snapping. often with no other warning. Inspect your springs periodically for discoloration, surface rust, or any visible stretching.
Why You Should Replace Both Springs at Once
If your garage door runs on a two-spring system and one spring breaks, it's worth replacing both at the same time. Both springs were installed together, have experienced the same number of cycles, and have worn at a similar rate. When one spring breaks, the second is often not far behind. Replacing both restores balanced lifting and reduces the likelihood of a second breakdown just weeks after the first repair. which is exactly the kind of emergency call no one wants to make in the middle of a February snowstorm.

Do Not Attempt This Repair Yourself
This needs to be stated plainly. Garage door springs are under extreme tension. hundreds of pounds of stored mechanical energy. When released improperly, they can cause broken fingers, facial injuries, or far worse. A 150,300 lb door without spring support can drop suddenly and without warning. Even experienced DIYers who are handy with home repairs should leave spring replacement to trained professionals with the right tools and winding bars.
If your spring has snapped, stop using the door entirely. Don't try to force it open manually, and don't keep running the opener. Contact Garage Door Haverhill and we'll get a technician out to assess the situation properly.
How Long Does Spring Replacement Take?
Most spring replacements take between one and two hours when handled by a professional. That includes removing the old springs, selecting the correct replacement matched to your door's weight, installing and tensioning the new springs, and testing door balance and opener performance. If other components were damaged when the spring failed. cables, rollers, or hardware. additional time may be needed to restore the full system safely.

Frequently Asked Questions
Q: How do I know whether I have torsion springs or extension springs? A: Torsion springs are the large coil(s) mounted horizontally on a metal rod directly above the garage door opening. Extension springs run along the horizontal tracks on either side of the door and look like long, stretched coils. Most newer homes have torsion systems; older homes in Haverhill's historic neighborhoods may have extension springs.
Q: My opener still runs when I press the button, but the door barely moves. Is that a spring problem? A: Most likely, yes. When a spring breaks, the opener tries to lift the full weight of the door with no counterbalance help. The motor runs, strains, and may move the door a few inches before the safety mechanism kicks in and stops it. This is a classic broken spring symptom. stop using the door and call for service.
Q: When one spring breaks, does the other one need replacing too? A: In most cases, yes. Both springs experience the same number of cycles and age at the same rate. If one has broken, the other is typically near the end of its life as well. Replacing both at the same time avoids a second service call in the near future and ensures the door lifts evenly without putting undue stress on cables and the opener motor.
