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

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