Pre-installation assessment before anything is ordered. Every specification — framing, track, spring, opener — confirmed for the specific opening. Balance test before the opener is commissioned. Every installation guaranteed in Dexter.
You're adding a garage door to a space that doesn't currently have one in Dexter. Before any door is ordered, three assessments determine whether the installation can proceed correctly in the opening as it exists in Dexter, MO. The header framing must have adequate load capacity for the torsion spring assembly that will be mounted to it in Dexter. The headroom clearance above the opening determines which track configurations are physically possible in the space in Dexter, MO. The side room on each side of the opening determines whether standard track and hardware can be positioned correctly in Dexter. Skip any one of these assessments and the consequence is a door that arrives for an opening it can't be correctly installed in, or a door that's installed but performs incorrectly from the first cycle because a constraint that should have been identified before ordering was discovered during installation instead in Dexter, MO. Call Herlihy Garage Doors now for a pre-installation assessment throughout Dexter in Dexter, MO.
Every specification set on installation day determines how this door performs for the next 15 to 20 years in Dexter. The spring specification established at installation is the specification under which the door operates for its entire service life in Dexter, MO. A spring correctly specified at installation produces a door that balances from the first cycle and keeps every connected component — opener, cables, rollers — at its designed operating load in Dexter. A spring incorrectly specified at installation produces a door that accumulates premature wear on every connected component from the first cycle and for every cycle after in Dexter, MO. The track configuration installed is the track configuration the door uses for its service life in Dexter. The opener selected is the opener that runs the door until it's replaced in Dexter, MO. There are no do-overs on installation day specifications without significant cost in Dexter. Getting them right the first time is what matters in Dexter, MO.
Herlihy Garage Doors performs new garage door installations throughout Dexter, MO in Dexter. Complete pre-installation assessment of the opening — framing load capacity, headroom clearance, side room, and electrical access — before any component is ordered in Dexter, MO. Door, track configuration, spring, and opener all selected with confirmed specifications before any equipment is purchased in Dexter. Track system installed from scratch in Dexter, MO. Spring wound to the correct turn count for the new door's specific weight and drum configuration in Dexter. Balance test confirms the specification before the opener is commissioned in Dexter, MO. Every installation guaranteed in Dexter. Built right from the start in Dexter, MO.
A replacement has an existing track to assess, an old door whose weight provides a spring specification reference, and an existing opener mount position in Dexter, MO. A new installation has none of these in Dexter. The track configuration is selected from zero based on the available headroom in Dexter, MO. The spring specification is calculated from zero based on the new door's construction characteristics in Dexter. The opener is selected from zero based on the door weight and the application requirements in Dexter, MO. Every specification is established from scratch in Dexter. The pre-installation assessment is what makes this possible before equipment is ordered in Dexter, MO.
The opening width is measured from the inside face of the finished jamb on each side in Dexter, MO. Standard residential door widths of 8, 9, 10, 16, and 18 feet accommodate most residential openings in Dexter. An opening that doesn't match a standard width within the manufacturer's tolerance requires a custom-manufactured door in Dexter, MO. An opening that measures 15 feet 9 inches wide doesn't accommodate a 16-foot door without framing modification in Dexter.
Headroom is the distance from the top of the door opening to the ceiling or the lowest obstruction above the opening in Dexter. Standard radius track requires approximately 10 to 12 inches of headroom above the door opening in Dexter, MO. Low-headroom track configurations accommodate spaces with as little as 6 to 8 inches in Dexter. A jackshaft opener mounted to the wall beside the door rather than overhead can accommodate even less headroom in specific configurations in Dexter, MO. The headroom measurement is the first constraint that determines which track configurations are compatible with the specific installation in Dexter.
Side room is the clearance available on each side of the opening for the vertical track and the spring end hardware in Dexter, MO. Standard torsion spring installations require approximately 3.75 inches of side room on each side for the vertical track and the end bearing plate in Dexter. Less than this on either side means the standard configuration can't be installed in the correct position without modification in Dexter, MO. Herlihy measures side room on both sides during the pre-installation assessment in Dexter.
The torsion spring assembly is mounted to the header framing above the door opening through the center bearing plate and end bearing plates in Dexter. The header must have adequate load capacity for the spring assembly load in Dexter, MO. A correctly sized residential header — typically a doubled 2x10 or 2x12 for standard opening spans — has adequate capacity in most cases in Dexter. A converted carport, a widened opening, or an original header that was undersized may not in Dexter, MO. Herlihy assesses the header framing as a standard component of every pre-installation assessment in Dexter.
The garage door opener requires a 120-volt electrical outlet within approximately 6 feet of the opener motor unit in Dexter, MO. In a new garage build, this outlet is typically part of the electrical rough-in in Dexter. In a converted carport or other space not originally designed as a garage, the outlet may not exist at the location needed in Dexter, MO. Herlihy confirms electrical access during the pre-installation assessment and advises on any electrical work needed before the installation date in Dexter.
Standard radius track uses a curved section with approximately a 12 to 15-inch radius to transition the door from vertical to horizontal travel in Dexter, MO. It requires 10 to 12 inches of headroom above the door opening in Dexter. It's the most common track configuration in residential installations and carries the broadest range of door weight ratings in Dexter, MO. Compatible with all standard residential opener configurations in Dexter.
Low-headroom track uses a tighter curve radius and a modified horizontal track angle to reduce the headroom requirement to 6 to 8 inches in Dexter. Required when the available headroom is insufficient for standard radius track in Dexter, MO. Requires specific low-headroom hardware including modified end bearing plates and drum configurations that accommodate the different track geometry in Dexter. Herlihy identifies the low-headroom requirement during the headroom measurement in the pre-installation assessment in Dexter, MO.
High-lift track extends the vertical section of the track above the standard height before curving to horizontal in Dexter, MO. Used when the garage has high ceilings and the homeowner wants to maximize the overhead space that would otherwise be used by the horizontal track in Dexter. Requires longer vertical track sections and a modified spring specification that accounts for the additional vertical travel distance before the door transitions to horizontal in Dexter, MO.
The track configuration determines the required headroom clearance, the required side room for the specific hardware, the correct spring winding calculation because the turn count changes with door travel distance, and which opener mounting positions are compatible with the specific track geometry in Dexter. Track configuration is selected first because every other major installation specification follows from it in Dexter, MO.
A replacement has an old door and old spring as a starting reference for the new spring specification in Dexter, MO. A new installation has no previous door and no previous spring in Dexter. The spring specification must be calculated entirely from the new door's construction characteristics and the installation's track and cable drum configuration in Dexter, MO. This makes the door weight determination step more critical in a new installation than in any replacement in Dexter.
The new door's weight is calculated from its width, height, steel gauge, insulation type and R-value, and window section configuration in Dexter. Each variable contributes a specific weight to the total in Dexter, MO. The manufacturer's specification sheet for the selected door provides the weight for the specific size and construction combination in Dexter. Herlihy uses the manufacturer's specified weight as the foundation for the spring specification in Dexter, MO.
The cable drum's groove pitch determines how many drum rotations are needed to travel the door's full height in Dexter, MO. The door height determines how many cable wraps are needed for a complete open cycle in Dexter. The drum rotations required for the complete open cycle equals the spring winding turn count required for that door on that drum in Dexter, MO. An incorrect drum specification in the winding calculation produces an incorrect turn count and an incorrectly balanced door from the first cycle in Dexter.
Every Herlihy new installation ends with the balance test before the opener is commissioned in Dexter. Opener disconnected in Dexter, MO. Door manually raised to the halfway position in Dexter. Door released and observed in Dexter, MO. Correct hold at the halfway height confirms the spring specification and winding are correct in Dexter. Rising indicates oversprung in Dexter, MO. Dropping indicates undersprung in Dexter. The winding is adjusted until correct balance is confirmed in Dexter, MO. The opener is not commissioned until the balance test is passed in Dexter.
A correctly specified spring wound to the correct turn count produces a door that balances from the first cycle in Dexter, MO. Every component in the load path — opener motor, drive gear, cables, rollers — operates at its designed load from the first cycle in Dexter. The correct spring specification at installation is the single most important factor in the door system's long-term component life in Dexter, MO.
Standard raised panel steel doors in single or double-layer construction are available in multiple profiles and finishes in Dexter, MO. Appropriate for most residential applications where thermal performance isn't the primary consideration in Dexter. The most cost-effective residential garage door option in Dexter, MO.
Insulated steel doors with polystyrene or polyurethane core construction significantly reduce thermal transfer through the door compared to uninsulated steel in Dexter. Polyurethane-insulated doors produce quieter operation because the foam core absorbs vibration in Dexter, MO. Available in R-values from R-6 to R-18 and above in Dexter. The weight difference from insulation must be accounted for in the spring specification in Dexter, MO.
Carriage house style doors use an overhead sectional mechanism with a traditional swing-door appearance in Dexter, MO. The most popular style for craftsman, colonial, farmhouse, and traditional architectural styles in Dexter. Available in a wide range of panel configurations, hardware styles, and window options in Dexter, MO.
Contemporary garage doors with flush panels, aluminum frames, and full-view glass sections are appropriate for modern, mid-century, and industrial architectural styles in Dexter. Full-view glass section doors provide natural light to the garage interior in Dexter, MO. Significantly heavier than steel panel doors and require specific spring, opener capacity, and track compatibility assessment in Dexter.
Non-standard opening widths and heights require custom-manufactured doors from most major manufacturers in Dexter, MO. Herlihy measures the specific opening and orders correctly sized custom doors where the opening dimensions require it in Dexter.
Chain drive openers are the most cost-effective opener type and are appropriate for detached garages where operational noise level doesn't affect adjacent living spaces in Dexter, MO. The chain mechanism produces more noise than belt or direct drive alternatives in Dexter.
Belt drive openers use a reinforced rubber belt that produces significantly less noise than a chain in Dexter. The correct choice for attached garages where the opener's operational sound travels through shared walls into the home interior in Dexter, MO. The additional cost over chain drive is justified by the noise reduction in every attached garage application in Dexter.
Direct drive openers move the motor unit itself along the rail rather than using a chain or belt in Dexter, MO. They produce less vibration and noise than any chain or belt system in Dexter. The correct choice when minimum opener noise is the highest priority — adjacent to a home office, nursery, or bedroom sharing a wall with the garage in Dexter, MO.
WiFi connectivity for smartphone control and monitoring from any location in Dexter. Battery backup for continued door operation during power outages in Dexter, MO. Automatic close timer that closes the door after a set interval if left open in Dexter. Rolling code security that changes the access code with every activation in Dexter, MO. Including these features from the initial installation costs less than retrofitting them later in Dexter.
The opener must have adequate rated capacity for the door's calculated weight in Dexter, MO. Most standard residential openers are rated for doors up to 150 or 200 pounds in Dexter. A heavier door requires a higher-capacity opener in Dexter, MO. Herlihy matches opener capacity to the new door's weight as a standard step in every new installation opener selection in Dexter.
