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