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

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