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

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