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

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