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

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