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

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