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

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