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

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