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

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