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

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