Ask any garage door technician working the Merrimack Valley what their busiest season is, and the answer is almost always late winter and early spring. In Lawrence, where temperatures regularly swing from the low twenties overnight to the forties during the day, that constant thermal cycling puts garage door springs under relentless stress. The metal expands and contracts repeatedly, and springs that are already near the end of their service life tend to give out right when you need your door most. on a cold Tuesday morning when you're already running late.
If you've never thought much about your garage door springs, now is a good time to get familiar with them. They're the component that does most of the actual work every time your door moves, and when they fail, they fail hard.
Garage doors are heavy. typically anywhere from 150 to 400 pounds depending on the material and size. Springs counterbalance that weight so the opener motor only has to handle a small fraction of the load. Without functioning springs, the door effectively becomes a multi-hundred-pound slab that the opener cannot safely lift.
There are two main types you'll encounter on Lawrence homes:
Torsion springs are mounted horizontally above the door opening and coil around a metal rod. They're the standard on most modern sectional doors and are generally safer and longer-lasting than the alternative. Torsion springs are rated for roughly 10,000 to 20,000 cycles, which translates to about 7 to 14 years of typical use.
Extension springs run alongside the horizontal tracks on either side of the door and work by stretching. You'll find these more often on older homes. and Lawrence has plenty of older housing stock, particularly in neighborhoods like Tower Hill and the North Common area where many of the homes date back to the early and mid-20th century. Extension springs have a shorter lifespan and can snap with significant force when they fail, potentially flying across the garage.
Springs rarely fail without warning. the problem is that most homeowners don't know what to look for. Here's what to watch:
- The door feels unusually heavy when you lift it manually. Disconnect the opener by pulling the red cord and try lifting the door by hand. It should feel relatively light. If it feels like you're lifting dead weight, the spring tension is gone or severely reduced. - The door opens only a few inches and stops. This is the opener detecting excessive resistance and reversing as a safety measure. Often a spring issue. - A visible gap in the spring coil. If you can see the torsion spring above your door and notice a separation in the coil. even a half inch. the spring has snapped. - A loud bang from the garage. This is the most dramatic and unmistakable sign. A snapping torsion spring under tension sounds like a gunshot. If you hear this and the door suddenly won't work, don't investigate. just stop using the door. - The door moves unevenly or one side hangs lower. Especially common when one spring in a two-spring system fails. - Rust or visible corrosion on the coils. In the Merrimack Valley, where Lawrence gets around 40 to 50 inches of precipitation annually including significant snowfall, moisture exposure accelerates rust. Corroded springs are weakened springs.

Look above your garage door when it's closed. If you see a horizontal spring (or pair of springs) running along a bar directly above the door opening, you have torsion springs. If you see springs running horizontally along the upper side tracks. one on each side. those are extension springs.
Homes in Lawrence's older neighborhoods often still have extension spring systems. While these work fine, many homeowners choose to upgrade to torsion springs when it's time to replace, since torsion springs are safer when they break (they stay contained on the bar rather than flying loose) and generally last longer.
Being honest about costs matters. Here's what you should expect to pay in the greater Merrimack Valley:
- Extension spring replacement: Typically $120 to $200 for a standard single door, parts and labor included. - Torsion spring replacement: Usually $150 to $350 per door. If you have a double-car door or need both springs replaced, budget toward the higher end of that range. - Labor: Service call fees in the greater Boston and northeastern Massachusetts area generally run $75 to $150 for the visit, which is typically rolled into the total estimate. - Upgrading from extension to torsion: This conversion costs more. generally $400 to $800. because it involves removing the old extension hardware and installing an entirely new torsion system. It's not required, but it's worth considering if your extension springs are at end of life.
One piece of advice worth emphasizing: always replace both springs at the same time, even if only one has broken. If one spring has hit the end of its life, the other is right behind it. Replacing just the broken one means you'll likely be scheduling another service call within a few months. and paying another labor fee.

This is one area where the honest answer is straightforward: don't do it yourself. Garage door springs are under extreme tension. enough force to cause serious injury or worse if released incorrectly. Professional technicians have specialized winding bars, safety cables, and training that make this work manageable. Without those tools and that experience, the risk isn't worth the savings.
This isn't a liability-driven disclaimer. It's just the reality of working with high-tension hardware. The money you'd save on labor isn't worth a trip to Holy Family Hospital.
If you're in Haverhill, Andover, or Methuen and dealing with the same issue, the advice is identical. this is a job for a trained tech regardless of what town you're in.
A standard torsion spring replacement by an experienced technician typically takes one to two hours. The tech will:
1. Safely release tension from the existing spring(s) 2. Remove the old spring and inspect the cable drums, cables, and hardware for wear 3. Install the correct replacement spring(s) sized for your specific door's weight 4. Re-tension the new springs and test the door balance 5. Lubricate all moving components and do a safety check on the opener's force settings
If the cables or drums are frayed or worn, a good technician will flag those during the visit. Addressing them at the same time saves you from a follow-up call.

Q: How long do garage door springs last in Lawrence's climate? A: Most torsion springs are rated for around 10,000 cycles, which works out to roughly 7 to 10 years with average daily use. Lawrence's climate. with significant temperature swings, heavy snow seasons, and humidity. can accelerate wear, particularly on springs exposed to moisture. If your springs are approaching the 7-year mark, it's worth having a tech take a look before they fail unexpectedly.
Q: Can I still use my garage door if I think the spring is worn but hasn't broken yet? A: Technically yes, but cautiously. A door with a weakening spring puts extra load on the opener motor with every cycle, which can shorten the opener's life as well. If the door feels noticeably heavier than it used to, moves unevenly, or is making new noises, get it inspected soon. Waiting for a full failure usually means a more urgent repair and sometimes additional damage to the opener.
Q: Do I need a permit to replace garage door springs in Lawrence, MA? A: No. spring replacement is considered standard maintenance and repair work, not a structural modification, so it doesn't require a building permit. Full garage door replacements may have different requirements depending on your situation. When in doubt, check with the Lawrence Garage Doors team or the city's building department.
