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

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