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

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