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

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