Frequently Asked Questions
Gate installation costs vary based on gate type, materials, and property layout. A basic sliding gate with operator typically starts around $3,000 to $5,000 for residential properties, while custom steel or wood gates with advanced access control can range from $7,000 to $15,000 or more. We provide free on-site estimates so you get an accurate quote for your specific project.
Most residential gate installations are completed in 1 to 3 days, depending on the complexity. A straightforward sliding gate with an existing post and power source can often be done in a single day. Custom fabrication, concrete work, or access control integration may extend the timeline to a week. We always provide a clear schedule before work begins.
If your gate operator is under 10 years old and the gate frame is structurally sound, repair is usually the better option. Common repairs like replacing a motor, control board, or safety sensors are far less expensive than a full replacement. However, if the gate has significant rust, structural damage, or an outdated operator that no longer has parts available, replacement may be more cost-effective in the long run. We'll give you an honest assessment either way.
Sliding gates move horizontally along a track or rail, making them ideal for driveways with limited space or uphill slopes. Swing gates open inward or outward like a door and require clearance in front of or behind the gate. Sliding gates are generally better for commercial properties and tight spaces, while swing gates offer a more traditional look and work well on flat, wide driveways. Our technicians can evaluate your property and recommend the best option.
Yes. We offer 24/7 emergency gate repair service throughout Los Angeles County and surrounding areas. If your gate is stuck open, closed, or malfunctioning, call us at (626) 421-7250 and we'll dispatch a technician as quickly as possible. Most emergency repairs are resolved the same day.
We are authorized dealers for all major gate operator brands, including LiftMaster, DoorKing (DKS), Viking Access Systems, FAAC, Nice, All-O-Matic, HySecurity, USAutomatic, Mighty Mule (GTO), and more. We'll recommend the right operator based on your gate size, usage frequency, and budget. All installations include full manufacturer warranty coverage.
We recommend professional maintenance at least once a year for residential gates and twice a year for commercial gates with heavy daily use. Regular servicing includes lubricating moving parts, checking safety sensors, inspecting wiring and connections, testing the operator, and adjusting limit switches. Routine maintenance prevents costly breakdowns and extends the life of your system. Check out our gate maintenance guide for tips you can do between service visits.
