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

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