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

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