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

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