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

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