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

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