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

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