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

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