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

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