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

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