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

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