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

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