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

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