Types of Automatic Gates

We install and service several types of automatic gates for residential and commercial properties in La Mirada. Each gate type offers unique benefits and security features to match different property layouts and access requirements.

Sliding Gates

Sliding gates move horizontally along a track and are perfect for properties with limited space. These gates slide parallel to the fence line, making them ideal for sloped driveways or areas where a swing gate might obstruct traffic. We use high-grade steel rollers and nylon wheels with sealed bearings for smooth, maintenance-free operation.

Swing Gates

Swing gates open like traditional doors, either as single or double panels. We commonly install these in residential settings where space permits the gate to swing inward or outward. Their classic appearance adds elegance to any property entrance. Our swing gate installations include heavy-duty hinges rated for twice the gate's weight, ensuring years of reliable service.

Cantilever Gates

Cantilever gates operate without ground tracks, using rollers mounted on support posts. This design works exceptionally well in areas with debris or uneven ground since there's no track to maintain or clear. Our cantilever systems use industrial-grade aluminum extrusions that won't rust, even during La Mirada's brief rainy season when the city receives most of its 14 inches of annual rainfall.

Vertical Lift Gates

Vertical lift gates move straight up and down, similar to a garage door. We typically install these in commercial or industrial settings where horizontal space is limited. They're excellent for securing loading docks and warehouse entrances. Our vertical lift systems feature counterweight balancing for energy efficiency and reduced motor wear.

Each gate type comes with our comprehensive labor guarantee in addition to manufacturer warranties on all components. 

Key Components of an Automatic Gate

An automatic gate system consists of several essential parts working together to provide secure and convenient access control. Let's examine the main components that make these systems function effectively.

Gate Operator

The gate operator serves as the primary motor that moves the gate. We exclusively install UL325-compliant operators that meet rigorous safety standards. Our team is factory-certified on Apollo, Viking, and FAAC operators, allowing us to provide expert repair and installation services for any brand.

Control Board and Electronics

The control board functions as the gate's brain, processing signals from various inputs. We install weather-resistant NEMA-rated housings to protect these sensitive electronic components from moisture and extreme temperatures. Our technicians receive specialized training in circuit board repair, enabling us to fix most control issues without complete replacement.

Safety Sensors and Devices

Safety features include photo eyes, pressure sensors, and obstruction detection systems. We position these devices strategically to prevent accidents and ensure compliance with safety regulations. All our installations exceed UL325 requirements with redundant safety systems to protect La Mirada's families, where 37% of households have children under 18.

Access Control Components

The access control system may include keypads, card readers, remote controls, or telephone entry systems. We customize these options based on security needs and user preferences. All our access control installations include surge protection and are backed by a parts warranty.

Common Issues and Troubleshooting

Automatic gates can experience various mechanical and electrical issues that affect their performance and reliability. Our licensed technicians quickly diagnose and resolve problems with a high same-day repair rate across La Mirada.

Gate Sensor Troubleshooting

Safety sensors are critical components that prevent accidents and damage. When sensors malfunction, gates may refuse to close or open unexpectedly.

We recommend checking the sensor alignment first. Clean the sensor lenses with a soft cloth to remove dirt and debris that can block the signal. Our repair technicians carry specialized alignment tools that

ensure precise positioning of safety photocells.

Loose wiring connections often cause intermittent sensor failures. We inspect all terminal connections and replace any corroded or damaged wires using only copper conductors with UV-resistant insulation.

Automatic Gate Troubleshooting

Gate operators may struggle with slow operation or complete failure. Dead batteries in the backup system are a common cause of operational issues.

We test the motor's voltage output and replace worn brushes that can cause jerky movement. Our diagnostic equipment can identify electrical issues that standard multimeters miss, allowing for precise repairs rather than costly replacements.

Chain drives require regular tension adjustments to prevent slipping. We check sprockets for wear and alignment to ensure reliable power transfer. All replacement chains are commercial-grade with a tensile strength 50% higher than residential grade.

Driveway Gate Troubleshooting

Track-based gates often develop alignment issues that cause binding or derailing. We adjust roller positions and track heights to restore proper movement. Our adjustments include laser-guided alignment to ensure precise track positioning.

Debris in the track creates obstruction points. Regular cleaning and inspection prevent accumulated dirt from damaging wheels and rollers. We install debris guards on all new installations to minimize maintenance needs.

Remote control problems typically stem from weak batteries or damaged antennas. We test signal strength and reprogram remotes when needed. Our advanced diagnostics can identify frequency interference issues common in dense residential areas.

System-Specific Repairs and Maintenance

Precision Automatic Gate Repair specializes in comprehensive repair services for all components of automated gate systems in La Mirada. Our service vehicles carry over 90% of commonly needed parts, allowing immediate repairs in most cases.

Gate Opener Repair and Maintenance

We service all major brands of gate opener systems, including LiftMaster, DoorKing, and Linear. Our technicians receive annual recertification on all major operator types, ensuring expert service on every call.

Gate motor replacement is one of our most common services. Signs that indicate motor replacement needs include unusual noises, slow operation, or complete failure to open or close. We provide same-day motor replacements with models that feature extended warranties exclusive to our company.

Access Control System Repairs

We repair and program keypad entry systems from basic digital keypads to advanced card readers. Our programming expertise extends to integrating gate systems with home automation platforms like Control4 and Crestron.

Intercom system repairs cover both audio and video units. We fix connection problems, replace damaged speakers, and upgrade outdated systems to modern digital alternatives. Our technicians are certified in structured wiring installation for reliable connectivity.

Safety Mechanism and Sensor Repairs

Safety sensors require precise alignment and regular testing to function correctly. We check and adjust photo eye beams to prevent false triggers and ensure reliable operation. Our technicians use calibrated test equipment to verify correct operation under various conditions.

Our technicians verify proper function of all safety features:

• Pressure sensitivity settings
• Obstacle detection systems
• Automatic reverse mechanisms
• Emergency release systems

We replace damaged sensor units and upgrade older systems to meet current safety standards. All our safety system upgrades include documentation certifying UL325 compliance, important for liability and insurance purposes.

Preventive Measures and Periodic Maintenance

Regular maintenance and preventive care significantly extend the lifespan of automatic gates while reducing repair costs and minimizing unexpected breakdowns. Our maintenance plans include priority service and discounted repair rates.

Routine Preventive Maintenance

We recommend inspecting gate hinges and rollers monthly for proper lubrication and smooth operation.

Our maintenance programs include scheduled service to ensure optimal performance year-round.



The gate's photocells and safety sensors need weekly cleaning with a soft cloth to ensure reliable operation. Our semi-annual maintenance includes complete safety system testing and certification documenting proper operation.

Check the gate operator's chain or belt tension every 3 months. Our technicians use calibrated tension meters to ensure precise adjustment, preventing premature wear and system failure.
