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

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