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

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