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

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