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

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