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

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