How We Work: Process & Technical Standards
What happens between your first call and a gate that works — and the standards we hold every job to.
Most gate problems we are called to fix were built in on day one: a post set too shallow, an operator sized to the limit, a safety device wired to be ignored. Greenbriar Gate Services follows the same sequence on every job, from a hinge replacement to a commercial slide gate, so those mistakes do not happen. This page explains it.
The seven steps of a gate job
| Step | What we do | What you get |
|---|---|---|
| 1. Call and triage | We ask what the gate is doing, how big it is, what kind of operator it has, and how urgent it is. Photos help. | An honest arrival window and, for repairs, the parts loaded on the truck. |
| 2. Site assessment | Measure the opening and the leaves; check slope, drainage and soil; find power and the shortest conduit route; note snow storage, sight lines and where cars will wait. | A design that fits the driveway you actually have. |
| 3. Written estimate | Gate design, material and finish; operator and safety devices; posts and footings; access control; permit needs; price and timeline. | One document you can compare and keep. |
| 4. Scheduling and materials | Custom gates are fabricated; operators and hardware are ordered; permit submitted if required; utilities located before digging. | A start date, and no surprises on it. |
| 5. Installation | Posts and footings first, cured before loading; then the gate hung and aligned; then the operator, safety devices and access control; wiring in conduit. | A gate that is square, plumb and easy to move by hand before it is ever powered. |
| 6. Testing and handover | Full cycles under power; limits and force settings tuned; every safety device tested with the gate moving; remotes, keypads and intercom programmed; manual release demonstrated. | A working gate and the knowledge to live with it. |
| 7. Follow-up | A check-in after the first weeks for installations; seasonal tune-ups available; warranty paperwork registered. | Someone to call who already knows your gate. |
Site assessment and load calculations
Before anything is ordered we work out what the gate will weigh, how the wind will load it, and what the posts have to carry. A 16-foot solid panel on an exposed driveway can see several hundred pounds of wind force, which is why hinge posts on big swing gates are set deeper and in more concrete than the fence line around them. We measure the actual opening rather than the drawing, check that the driveway slope will not let a swing leaf hit the ground as it opens, and decide track versus cantilever from how the driveway drains and where the plow pushes snow.
Installation sequence
- Layout and utilities. Underground utilities are located, then the post positions are staked so the gate sits where the cars need it to be.
- Footings. Holes are dug below the frost line — about 36 to 42 inches in Cuyahoga County — with a gravel base for drainage, and posts are set plumb in concrete. Conduit for power and safety devices goes in the same trench.
- Cure time. We do not hang a gate on green concrete. Posts cure before they carry a load.
- Hanging and alignment. Hinges or rollers are set for the gate's weight with room to adjust; the gate is leveled, the latch aligned, and it is moved by hand until it moves easily — an operator should never be used to overcome a stiff gate.
- Operator and safety devices. The operator is mounted per the manufacturer's geometry, then photo eyes, safety edges and loops are wired and monitored, limits and forces are set, and warning signs go up.
- Access control. Keypads, remotes, intercoms and readers are installed and programmed, with a list of codes and credentials handed to you.
Safety code compliance: UL 325 and ASTM F2200
Automated gates are installed to the current edition of UL 325, the safety standard for gate operators, and the gates themselves are built to ASTM F2200, the construction standard for gates that will be automated. In practical terms that means:
- At least two independent, monitored means of entrapment protection in each direction of travel where a person could be caught — typically photo eyes plus contact edges, in addition to the operator's own obstruction sensing.
- Operators of the correct UL 325 class for the property (residential Class I through restricted-access Class IV).
- No openings in the gate or adjacent fence that a hand or head can pass through in the travel zone; guard screens where needed.
- No protruding rollers, hardware or sharp edges in the path of a person; positive stops on slide gates.
- A manual release, warning placards on both sides, and a clear line of sight or a camera where the gate cannot be seen from the control.
- Local requirements on top: fire-department access, pool-gate hardware, height and setback rules from the city permit.
How we diagnose a malfunctioning opener
Opener troubleshooting is done in a fixed order so we do not replace parts on a hunch. First the gate itself: release the operator and move the gate by hand; if it binds, the problem is mechanical and no electronics will fix it. Then power: incoming voltage, transformer, fuses, and battery condition under load. Then the control board's diagnostics and the limit settings. Then the safety inputs one at a time — a blocked photo eye or a shorted edge will stop a perfectly good operator. Only then the motor, capacitor and drive. Most calls are resolved at step one or four.
Quality benchmarks
| Item | Our standard |
|---|---|
| Gate post footings | Below the local frost line, concrete, drained base; sized for gate weight and wind load |
| Gate alignment | Leaf level and plumb; consistent gap to the ground; latch meets the strike without lifting |
| Hardware rating | Hinges, rollers and operators rated above the gate's weight and width, not at the limit |
| Wiring | Low-voltage and line-voltage in separate conduit; weather-rated connections; drip loops at every box |
| Safety devices | Monitored photo eyes and edges tested with the gate moving; force and limit settings recorded |
| Finish | Welds ground and sealed; cut steel primed; hardware galvanized or stainless |
| Handover | Walkthrough, manual-release demonstration, programmed credentials, written warranty terms |
Warranty-backed workmanship
Our workmanship is guaranteed: if a post moves, a hinge we installed fails, or an operator we installed was set up wrong, we come back and make it right. Operators and hardware carry their manufacturers' warranties, which we register for you and handle if a claim is ever needed. The specific terms are written on your estimate so there is nothing to remember.
Process questions
Do you give a written estimate?
Yes, for every installation and for any repair beyond a straightforward service call. It lists the gate or parts, the operator and safety devices if any, the work included, the price and the timeline. Changes along the way are agreed with you before they happen.
What is covered by the warranty?
Our workmanship — the way the gate is hung, the posts are set and the operator is installed — is guaranteed. Operators and hardware carry their manufacturers' warranties, which we register and handle for you. Ask for the specific terms for your job; they are written on the estimate.
Do you handle permits?
We tell you whether your city requires one, prepare the drawings and measurements the application needs, and can submit it for you. Requirements differ between Parma, Parma Heights, Seven Hills and the other suburbs, so we check each time rather than assume.
