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

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