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

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