Correct specification. Professional winding bars. Balance test before the opener is reconnected. Every spring repair guaranteed in Cowarts. Do not run the opener after a spring snap in Cowarts, AL.
The door feels heavier than it used to when you lift it manually in Cowarts — the spring is losing tension and the door weight is progressively shifting to the opener, the cables, and your effort in Cowarts, AL. The opener strains audibly and the door moves more slowly than it should in Cowarts — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Cowarts, AL. Or a spring snapped — you heard the bang and the door won't move in Cowarts. Call Herlihy Garage Doors now for same-day spring repair throughout Cowarts, AL in Cowarts. Do not run the opener and do not attempt to manually lift the door after a spring snap in Cowarts, AL.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Cowarts. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Cowarts, AL. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Cowarts. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Cowarts, AL. The winding cone has four holes designed for professional winding bars of a specific diameter in Cowarts. A winding bar that fits these holes correctly maintains contact throughout the winding process in Cowarts, AL. 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 Cowarts. When it slips, the stored energy releases instantly and the cone rotates at high speed in Cowarts, AL. The improvised tool becomes a projectile in Cowarts. This is not a theoretical risk in Cowarts, AL. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Cowarts.
Herlihy Garage Doors repairs and replaces garage door springs throughout Cowarts, AL in Cowarts. The correct specification is measured from the specific door configuration before any spring is selected in Cowarts, AL. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Cowarts. The balance test confirms the specification is correct before the opener is reconnected in Cowarts, AL. Same-day service available throughout Cowarts in most cases in Cowarts, AL. And every spring repair is guaranteed in Cowarts.
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 Cowarts. An oversprung door can behave dangerously under manual operation in Cowarts, AL. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Cowarts. Neither produces the correctly balanced door that every other component in the system depends on in Cowarts, AL. Herlihy Garage Doors measures the correct specification before any spring is selected in Cowarts.
The spring specification determines the door's balance in Cowarts, AL. The door's balance determines the load the opener, cables, and rollers operate under in Cowarts. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Cowarts, AL. The spring specification is the foundation variable from which everything else in the system's performance follows in Cowarts.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Cowarts, AL. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Cowarts. The winding stores rotational energy in the spring coil in Cowarts, AL. 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 Cowarts. 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 Cowarts, AL. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Cowarts.
Extension springs run horizontally along the upper track sections on each side of the door in Cowarts. They store energy by stretching rather than rotating in Cowarts, AL. When the door closes, the springs extend and store energy in their stretched length in Cowarts. 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 Cowarts, AL. 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 Cowarts. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Cowarts, AL.
Wire diameter determines how much energy the spring stores per turn in Cowarts, AL. A heavier wire diameter stores more energy per turn than a lighter one in Cowarts. Inside diameter determines which shaft size the spring fits on in Cowarts, AL. Length determines the total number of active coils and therefore the total energy storage capacity in Cowarts. 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 Cowarts, AL.
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 Cowarts. Winding it to the correct turn count produces insufficient lifting force in Cowarts, AL. The door is undersprung in Cowarts. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Cowarts, AL. Each coil must be wound tighter than designed to produce the required energy storage in Cowarts. The spring is more likely to fail before its rated cycle life in Cowarts, AL.
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 Cowarts, AL. Door height and cable drum size determine the correct winding turn count in Cowarts. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Cowarts, AL. The specification is calculated, not estimated in Cowarts.
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 Cowarts, AL. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Cowarts. That energy is stored in the spring coil as rotational tension on a steel shaft in Cowarts, AL. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Cowarts. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Cowarts, AL.
The winding cone has four holes sized for professional winding bars of a specific diameter in Cowarts. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Cowarts, AL. The length provides leverage and clearance in Cowarts. The correct diameter fit prevents the bar from shifting in the hole during winding in Cowarts, AL. Any movement of the bar in the hole during winding is a slip hazard in Cowarts.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Cowarts, AL. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Cowarts. The cone rotates rapidly in Cowarts, AL. The tool that was in the hole becomes a projectile in Cowarts. 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 Cowarts, AL. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Cowarts.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Cowarts. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Cowarts, AL. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Cowarts. That positioning is as important as the correct tools in Cowarts, AL.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Cowarts, AL. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Cowarts. They've accumulated the training repetitions that make correct positioning automatic in Cowarts, AL.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Cowarts, AL. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Cowarts. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Cowarts, AL.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Cowarts. The motor runs at a higher load than designed in Cowarts, AL. It produces more heat. It accumulates wear faster in Cowarts. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Cowarts, AL.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Cowarts, AL. The bang is often heard throughout the home in Cowarts. The door either drops if in motion or stays at its current position in Cowarts, AL. The opener runs but the door won't follow in Cowarts. Do not run the opener after a spring snap in Cowarts, AL.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Cowarts. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Cowarts, AL. A visible gap means complete spring failure in Cowarts. The door should not be operated until the spring is replaced in Cowarts, AL.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Cowarts, AL. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Cowarts. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Cowarts, AL.

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