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

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