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

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