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

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