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

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