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

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