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

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