Correct specification. Professional winding bars. Balance test before the opener is reconnected. Every spring repair guaranteed in Pocahontas. Do not run the opener after a spring snap in Pocahontas, IA.
The door feels heavier than it used to when you lift it manually in Pocahontas — the spring is losing tension and the door weight is progressively shifting to the opener, the cables, and your effort in Pocahontas, IA. The opener strains audibly and the door moves more slowly than it should in Pocahontas — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Pocahontas, IA. Or a spring snapped — you heard the bang and the door won't move in Pocahontas. Call Herlihy Garage Doors now for same-day spring repair throughout Pocahontas, IA in Pocahontas. Do not run the opener and do not attempt to manually lift the door after a spring snap in Pocahontas, IA.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Pocahontas. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Pocahontas, IA. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Pocahontas. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Pocahontas, IA. The winding cone has four holes designed for professional winding bars of a specific diameter in Pocahontas. A winding bar that fits these holes correctly maintains contact throughout the winding process in Pocahontas, IA. An improvised tool — a screwdriver, a piece of rebar, anything that doesn't fill the hole correctly — can slip out of the cone at any point in the winding process in Pocahontas. When it slips, the stored energy releases instantly and the cone rotates at high speed in Pocahontas, IA. The improvised tool becomes a projectile in Pocahontas. This is not a theoretical risk in Pocahontas, IA. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Pocahontas.
Herlihy Garage Doors repairs and replaces garage door springs throughout Pocahontas, IA in Pocahontas. The correct specification is measured from the specific door configuration before any spring is selected in Pocahontas, IA. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Pocahontas. The balance test confirms the specification is correct before the opener is reconnected in Pocahontas, IA. Same-day service available throughout Pocahontas in most cases in Pocahontas, IA. And every spring repair is guaranteed in Pocahontas.
A spring replaced with an incorrect specification — wrong wire diameter, wrong inside diameter, or wrong length — produces a door that's either oversprung or undersprung regardless of how correctly it's wound in Pocahontas. An oversprung door can behave dangerously under manual operation in Pocahontas, IA. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Pocahontas. Neither produces the correctly balanced door that every other component in the system depends on in Pocahontas, IA. Herlihy Garage Doors measures the correct specification before any spring is selected in Pocahontas.
The spring specification determines the door's balance in Pocahontas, IA. The door's balance determines the load the opener, cables, and rollers operate under in Pocahontas. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Pocahontas, IA. The spring specification is the foundation variable from which everything else in the system's performance follows in Pocahontas.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Pocahontas, IA. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Pocahontas. The winding stores rotational energy in the spring coil in Pocahontas, IA. When the door opens, the spring unwinds and releases that stored rotational energy through the shaft and drums, lifting the cables and the door in Pocahontas. The spring is wound to a specific tension that produces a lifting force equal to the door's weight at the cable drum attachment points in Pocahontas, IA. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Pocahontas.
Extension springs run horizontally along the upper track sections on each side of the door in Pocahontas. They store energy by stretching rather than rotating in Pocahontas, IA. When the door closes, the springs extend and store energy in their stretched length in Pocahontas. Extension springs can break with significant lateral movement because the stored energy is released along the spring's length rather than through a shaft in Pocahontas, IA. Safety cables threaded through the center of each extension spring are required to contain a broken spring and prevent it from becoming a projectile in Pocahontas. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Pocahontas, IA.
Wire diameter determines how much energy the spring stores per turn in Pocahontas, IA. A heavier wire diameter stores more energy per turn than a lighter one in Pocahontas. Inside diameter determines which shaft size the spring fits on in Pocahontas, IA. Length determines the total number of active coils and therefore the total energy storage capacity in Pocahontas. All three must be correct for the spring to produce the correct counterbalancing force for the specific door when wound to the correct turn count in Pocahontas, IA.
A spring with the correct inside diameter and length but a wire diameter one gauge too light stores less energy per turn than needed in Pocahontas. Winding it to the correct turn count produces insufficient lifting force in Pocahontas, IA. The door is undersprung in Pocahontas. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Pocahontas, IA. Each coil must be wound tighter than designed to produce the required energy storage in Pocahontas. The spring is more likely to fail before its rated cycle life in Pocahontas, IA.
Herlihy Garage Doors determines the correct spring specification through measurement of the existing spring where intact, or through calculation from the door's measured dimensions and construction characteristics where the spring has failed in Pocahontas, IA. Door height and cable drum size determine the correct winding turn count in Pocahontas. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Pocahontas, IA. The specification is calculated, not estimated in Pocahontas.
A standard residential torsion spring for a 200-pound garage door stores approximately 300 to 400 foot-pounds of rotational energy when wound to operating tension in Pocahontas, IA. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Pocahontas. That energy is stored in the spring coil as rotational tension on a steel shaft in Pocahontas, IA. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Pocahontas. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Pocahontas, IA.
The winding cone has four holes sized for professional winding bars of a specific diameter in Pocahontas. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Pocahontas, IA. The length provides leverage and clearance in Pocahontas. The correct diameter fit prevents the bar from shifting in the hole during winding in Pocahontas, IA. Any movement of the bar in the hole during winding is a slip hazard in Pocahontas.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Pocahontas, IA. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Pocahontas. The cone rotates rapidly in Pocahontas, IA. The tool that was in the hole becomes a projectile in Pocahontas. The person holding the tool, whose hands were near the winding cone, is in the path of both the rotating cone and the released tool in Pocahontas, IA. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Pocahontas.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Pocahontas. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Pocahontas, IA. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Pocahontas. That positioning is as important as the correct tools in Pocahontas, IA.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Pocahontas, IA. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Pocahontas. They've accumulated the training repetitions that make correct positioning automatic in Pocahontas, IA.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Pocahontas, IA. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Pocahontas. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Pocahontas, IA.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Pocahontas. The motor runs at a higher load than designed in Pocahontas, IA. It produces more heat. It accumulates wear faster in Pocahontas. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Pocahontas, IA.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Pocahontas, IA. The bang is often heard throughout the home in Pocahontas. The door either drops if in motion or stays at its current position in Pocahontas, IA. The opener runs but the door won't follow in Pocahontas. Do not run the opener after a spring snap in Pocahontas, IA.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Pocahontas. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Pocahontas, IA. A visible gap means complete spring failure in Pocahontas. The door should not be operated until the spring is replaced in Pocahontas, IA.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Pocahontas, IA. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Pocahontas. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Pocahontas, IA.

Opener disconnected. Door manually lifted to halfway position in Pocahontas, IA. Door released and observed in Pocahontas. Holds at halfway — specification confirmed correct in Pocahontas, IA. Rises — oversprung, winding adjusted in Pocahontas. Drops — undersprung, winding adjusted in Pocahontas, IA. Opener reconnected only after balance test confirms correct specification in Pocahontas.
Both springs were installed at the same time and have completed the same number of cycles in Pocahontas, IA. Metal fatigue accumulates proportionally to cycles under stress in Pocahontas. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Pocahontas, IA. The surviving spring is at essentially the same point in its fatigue progression in Pocahontas.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Pocahontas, IA. When the second spring breaks — and at the same fatigue progression it will — the cost is a second call-out charge, a second spring, and potentially a second after-hours charge in Pocahontas. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Pocahontas, IA.
If the surviving spring was replaced recently and has significantly fewer cycles than the broken spring, replacing only the broken spring is the correct approach in Pocahontas. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Pocahontas, IA. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Pocahontas. The specific reasoning is explained clearly in Pocahontas, IA. The homeowner makes the final decision with complete information in Pocahontas. Herlihy never withholds the reasoning or pressures the outcome in Pocahontas, IA.
