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

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