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

Spring wound to the calculated turn count using professional winding bars in Delft Colony. Set screws tightened to correct specification in Delft Colony, CA. Cables reattached to drums with correct tension in Delft Colony.
Opener disconnected. Door manually lifted to halfway position in Delft Colony, CA. Door released and observed in Delft Colony. Holds at halfway — specification confirmed correct in Delft Colony, CA. Rises — oversprung, winding adjusted in Delft Colony. Drops — undersprung, winding adjusted in Delft Colony, CA. Opener reconnected only after balance test confirms correct specification in Delft Colony.
Both springs were installed at the same time and have completed the same number of cycles in Delft Colony, CA. Metal fatigue accumulates proportionally to cycles under stress in Delft Colony. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Delft Colony, CA. The surviving spring is at essentially the same point in its fatigue progression in Delft Colony.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Delft Colony, 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 Delft Colony. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Delft Colony, 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 Delft Colony. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Delft Colony, CA. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Delft Colony. The specific reasoning is explained clearly in Delft Colony, CA. The homeowner makes the final decision with complete information in Delft Colony. Herlihy never withholds the reasoning or pressures the outcome in Delft Colony, CA.
