Garage Door Spring Repair Marathon, FL
Homeowners across Marathon and the surrounding area call us for spring repair because we know Marathon. The common drivers locally are corroded bottom brackets on older coastal doors, degraded weatherstripping from constant UV and salt, intermittent sensors fouled by morning damp, and salt-pitted spring coils that fail early near the coast — and we fix the cause, not just the symptom.
Ask any Marathon tech and they'll tell you the climate decides what fails. Year-round heat and humidity, frequent tropical downpours, and salt-tinged moisture that never lets metal fully dry brings storm-season wind that stresses panels and bottom seals, relentless UV and salt that degrade rubber weatherstripping, and constant humidity that swells wood doors and rusts steel hardware, year after year.
Run down the service log for Marathon and the same repairs repeat: corroded bottom brackets on older coastal doors, degraded weatherstripping from constant UV and salt, intermittent sensors fouled by morning damp, and salt-pitted spring coils that fail early near the coast. We carry every part needed to close them out in one trip.
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.
Signs you need spring repair
Loud bang from the garage
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.
