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

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