Homeowners across Saint Louis Hills, Princeton Heights, Southampton and Bevo Mill call us for spring repair because we know Shrewsbury. The common drivers locally are pitted galvanized hardware on older doors, mildew and rust on shaded, north-facing doors, swollen, sticking wood doors in summer humidity, and corroded springs and cables in the humid air — and we fix the cause, not just the symptom.
Because Shrewsbury has a warm, humid climate of sultry summers, abundant rainfall, and damp conditions that work hard on metal hardware, the doors here age differently than inland or coastal homes elsewhere. The usual culprits are frequent thunderstorms that drive rain into tracks and seals, salt-tinged coastal air that accelerates rust near the shore, and summer heat and moisture that swell wood doors and seize rollers — exactly what our techs come prepared for.
The calls we get most in Shrewsbury are pitted galvanized hardware on older doors, mildew and rust on shaded, north-facing doors, swollen, sticking wood doors in summer humidity, and corroded springs and cables in the humid air. Each is something our trucks are stocked to fix on the first visit — no waiting on parts.
Garage door springs are the single most-loaded component on the entire system — a typical residential torsion spring stores enough energy to lift a 200-pound door dozens of times a day. When that spring fatigues or snaps, the door becomes unsafe to operate by hand and dangerous to operate with an opener. Our spring repair service replaces broken or worn springs, recalibrates door balance, and verifies the entire counter-weight system so the door lifts evenly and the opener does not strain.
We carry a full inventory of torsion springs, extension springs, and 30,000-cycle high-cycle springs sized for the most common residential door weights nationwide. Most homeowners are running 10,000-cycle springs from a builder install; upgrading to 30,000-cycle springs at replacement time costs only marginally more and triples expected lifespan. Every spring repair includes a full balance test, photo-eye verification, and an opener force/travel calibration.
Spring work is one of the few garage door repairs where DIY genuinely puts you at risk. The torque stored in a fully-wound torsion spring can release a winding bar at high velocity if the bar slips. Our techs are CSLB-licensed and carry liability coverage for spring work; calling a professional almost always costs less than an emergency-room visit.
A failed torsion spring makes a distinct sharp crack that homeowners often mistake for a gunshot or a transformer blowing. Inspect the spring above the door for a visible 2-inch gap between coils.
Door feels twice as heavy
If the door is hard to lift by hand or the opener strains and reverses partway up, the spring is undertensioned, worn, or broken. A balanced door should lift with one hand.
Door drops fast when released
Disconnect the opener and lift the door to chest height. If you let go and it slams down, the spring is no longer counter-weighting the panels correctly.
Opener motor whines but door barely moves
Modern openers protect themselves by reversing under load. A failing spring forces the motor into that protection mode and shortens the opener's life if not corrected.
Visible gap in the torsion spring coil
Healthy torsion springs are wound tight along their full length. Even a half-inch gap between coils indicates a snapped spring — call before attempting to use the door.
Common causes & what we fix
Cycle fatigue
Every open-and-close is one cycle. Builder-grade springs are rated for ~10,000 cycles — roughly 7–10 years of typical use. Heavy users (3+ cycles/day) see failure earlier.
Corrosion from coastal air
Homes in coastal see accelerated corrosion on uncoated springs. Salt-air pitting weakens the wire and triggers premature snaps.
Improper spring sizing
If a builder undersized the original springs for the door weight, the spring runs at higher stress per cycle and fails years early. We size replacements by measured door weight, not guess.
Missing lubrication
Torsion springs need a light coat of oil annually to prevent friction wear between coils. A dry spring fatigues 30–40% faster than a maintained one.
Door imbalance
Sagging panels or off-track travel transfer load unevenly to the springs, accelerating failure on the over-loaded side. Repair work should always include a balance check.

Frequently asked about spring repair
Top questions homeowners searching for Spring Repair near me ask us:
Shrewsbury sits in a warm, humid climate of sultry summers, abundant rainfall, and damp conditions that work hard on metal hardware. That is hard on a door — frequent thunderstorms that drive rain into tracks and seals, salt-tinged coastal air that accelerates rust near the shore, and summer heat and moisture that swell wood doors and seize rollers all accelerate wear on springs, seals, and openers, so the failures we see most here are pitted galvanized hardware on older doors, mildew and rust on shaded, north-facing doors, swollen, sticking wood doors in summer humidity, and corroded springs and cables in the humid air. We size springs and seals for Missouri's humid subtropical region conditions rather than a generic catalog spec.
The call we get most in Shrewsbury is pitted galvanized hardware on older doors. Shrewsbury has mostly suburban single-family homes with attached garages, alongside pockets of older in-town housing, so mildew and rust on shaded, north-facing doors turns up often too. We carry the common parts on the truck for a single-visit fix.
Standard springs are backed 5 years; 30,000-cycle springs for the life of the original homeowner. The 10-year workmanship guarantee covers the install labor itself.
For most households, yes. The extra cost over a standard 10,000-cycle spring is small compared with the labor savings of avoiding two future replacements. We back 30,000-cycle springs for the life of the original homeowner.
We strongly recommend replacing both. Springs on a dual-spring door wear at the same rate, so the second spring is statistically days or weeks from failing. Replacing both at once costs less than two separate dispatches and re-balances the system properly.
Yes — but it will work better. New springs change the door's counter-weight, so we re-program the opener's travel and force limits as part of the visit. This is included in the flat-rate price.
