Hollis homes built around 1979 run wood and early steel doors on worn torsion hardware. We drive out from Londonderry, 13 miles away, to fix them right.
A spring swap on a single door runs different money than a full double-door opener job, and we won't quote either without seeing the door. What we can tell you is what tends to drive the number up in Hollis specifically: the median home here was built around 1979, which means a lot of original hardware is still in place. That's 45-plus-year-old torsion springs, galvanized cable that's never been replaced, and in some cases the old heavier wood-panel doors that newer steel sections don't match in weight. Parts for that era aren't always on the truck, which can mean a second trip if the first one turns up something we didn't expect. With median household income in this area at $156,140, we see more owners choose full replacement over patching old parts once a door's past a certain point - not because the repair is impossible, but because sinking money into 45-year-old rollers and hinges rarely pencils out next to a new door. We'll tell you straight which side of that line your door is on before we start.
What the Fix Involves
On a door this age, the fix usually starts with the torsion spring and the drum, not the opener. Houses built around 1979 were almost always set up with a single torsion spring on a center bracket, sized for a heavier wood or early steel door - not the lighter insulated steel panels sold today. When that spring goes, the door doesn't just stop opening, it can drop fast, because the cable and drum on these older setups weren't built with the safety margins current code expects. We check the drums for wear grooves, the cable for fraying near the bottom bracket, and the track alignment, since 45 years of settling shifts a jamb more than people expect. If the opener's original to the house, it's almost certainly a chain-drive unit without the travel limits and force sensors required in new installs, and that's often the bigger safety issue than the spring itself.
The Symptom
The call we get most from this side of town is a door that's suddenly heavy - it was fine yesterday, and today it won't lift past waist height, or it drops the last foot on its own. That's a broken or badly weakened torsion spring, and on a door built to 1979-era weight specs, it's not something to force past with the opener motor. Running the opener against a broken spring burns out the motor or strips the gear, turning a spring job into a spring-and-opener job. New Hampshire's winters are hard on this hardware too - cold makes steel brittle and springs fail more often in the cold months than the warm ones. If your door's groaning, sagging on one side, or the cable looks loose at the bottom bracket, that's the hardware telling you it's near the end, not a lubrication problem.
The DIY Question
Torsion springs are under real load - enough to break fingers or worse - and we don't recommend touching one without the right bars and clamps, full stop. What you can check yourself: the bottom brackets for rust-through, the track for gaps against the rollers, and whether the door is balanced (it should hold steady at waist height when disconnected from the opener, not slam down or fly up). If it doesn't hold, that's a spring problem, not an opener problem, and it's not a weekend fix. One honest limit on our end - we don't carry every obsolete part for a 1979-era wood door on the truck, so if your door needs a specific discontinued panel rather than a spring or cable, we'll tell you that up front instead of running a parts search on your dime.

How far out is Londonderry Garage Door Pros from Hollis?
About 13 miles. We don't keep a branch in Hollis - we run the truck out from Londonderry for every call, so scheduling depends on the day's route, not a local depot.
Why does a 1979-built house need different parts than a newer one?
Doors from that era were sized and sprung for heavier wood or early steel panels, often with a single center-bracket torsion spring and a chain-drive opener. That hardware doesn't match what's stocked for today's lighter insulated steel doors, so a repair sometimes takes an extra trip to source the right part.
Is it worth replacing an old door instead of repairing it?
Depends on the door. If the panels and track are sound and it's just a spring or cable, repair makes sense. If the opener, track, and spring are all original and failing together, replacement often costs about the same as stacking repairs and gets you current safety features new code expects.
Does winter weather affect spring failures here?
Yes. Cold makes steel more brittle, and torsion springs under tension fail more often in the coldest months. If your door's been sluggish or groaning, it's worth having the spring checked before deep winter rather than during a cold snap.
