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

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