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

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