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

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