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

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