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

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