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

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