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

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