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

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