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

Both springs were installed at the same time and have completed the same number of cycles in Fortville, IN. Metal fatigue accumulates proportionally to cycles under stress in Fortville. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Fortville, IN. The surviving spring is at essentially the same point in its fatigue progression in Fortville.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Fortville, IN. 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 Fortville. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Fortville, IN.
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 Fortville. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Fortville, IN. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Fortville. The specific reasoning is explained clearly in Fortville, IN. The homeowner makes the final decision with complete information in Fortville. Herlihy never withholds the reasoning or pressures the outcome in Fortville, IN.
