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

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