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

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