Frequently Asked Questions

We arrive in a marked window, text when we're on the way, and start with a full diagnostic. The technician tests every subsystem: the operator motor, limit switches, safety photo eyes, edge sensors, control board, and all wiring connections. We photograph what we find, explain it in plain terms, and give you a written quote before any work begins. Once approved, we repair, test every safety function, and leave you with a documented record of the settings and any parts replaced. That's Haven Clause 4: evidence on every job, and Clause 2: arrive on schedule with a named tech.

Most residential gate repairs take between 45 minutes and three hours. A failed LiftMaster operator swap on a standard swing gate in Sunnyvale's Ponderosa neighborhood might run 90 minutes including testing. Tracking down an intermittent short in underground conduit near the Caltrain corridor, where moisture and vibration take their toll, can stretch to half a day. We don't charge by the hour; our written quote is flat. If we hit something unexpected, we explain it, document it, and quote the additional work before proceeding. No scope creep, per Haven Clause 5.

We repair swing gates, sliding gates, cantilever gates, vertical lift gates, and barrier arms from every major manufacturer. Our Sunnyvale team works on residential driveway gates, commercial parking access systems, and multi-tenant entry systems throughout the South Bay. We carry common parts for DoorKing, Elite, LiftMaster, and Mighty Mule operators, and we can source components for discontinued brands. If your gate is custom-fabricated steel from a local welder or an imported aluminum system, we diagnose the electrical and mechanical systems the same way: methodically, with documentation.

We handle the complete gate system, including the low-voltage control wiring, safety device loops, and the power run from your electrical panel to the operator. In Sunnyvale, any new 240V dedicated circuit requires a permit and must be installed by a C-10 licensed electrician. We coordinate that work; our crews include or subcontract the electrical portion as needed, and it's always included in your written scope. You don't manage two contractors. We handle the permit, the inspection, and the documentation that proves it was done to code.

For Sunnyvale's typical residential driveway gates, we most often install LiftMaster and DoorKing operators. LiftMaster's residential line handles the moderate gate weights and cycle counts we see in neighborhoods like Serra and Ortega well, with good warranty support and available parts. DoorKing's commercial-grade units hold up better on multi-tenant properties along El Camino Real or in the Moffett Park office corridor, where gates cycle hundreds of times daily. We don't push one brand; we spec what matches your gate's weight, length, daily cycles, and your preference for smartphone integration or keyed access.

We use OEM parts whenever possible, and we tell you which we're installing before we start. Original Elite or LiftMaster control boards, gear assemblies, and safety sensors carry the manufacturer's warranty and are designed for your operator's exact specifications. In some cases, a quality aftermarket part makes sense for an older unit where OEM is discontinued or prohibitively expensive. We document what we installed, photograph the part markings, and note the warranty terms in your job record. Haven Clause 4 means you have evidence of what was actually done, not just a verbal assurance.

Often yes, though it depends on the manufacturer and how long ago production ended. We maintain relationships with regional distributors and salvage networks that stock discontinued DoorKing and Elite components. For operators more than fifteen years old, we sometimes recommend replacement over repair, not because we can't find parts, but because newer units offer better safety features, smartphone connectivity, and energy efficiency that justify the investment. We explain both options with written pricing for each, and you decide. No upsell pressure, per Haven Clause 5.

Every pro working under our name is required to hold the license and insurance California requires for the work they perform. That means a C-61/D-49 contractor license for gate and door work, general liability insurance, and workers' compensation coverage. We verify these credentials before anyone is dispatched to a Sunnyvale home. Haven Clause 3 is "Verified crews," and we put the license number on your written quote so you can check it yourself with the CSLB. We don't ask you to trust us on our word alone.

Yes, when permits are required. Sunnyvale follows California Building Code and Santa Clara County amendments for automated gate installations. Any new operator installation, structural modification, or electrical circuit addition requires a permit. We handle the application, the plans, the inspection scheduling, and the final sign-off. You receive copies of the approved permit and inspection records with your job documentation. Working without a permit saves nothing; it voids your insurance coverage and creates liability if someone is injured. We don't do it, and we don't work with homeowners who ask us to skip it.

Check the CSLB license number, confirm active general liability and workers' comp insurance, and ask for a written quote with a flat price before work starts. Then read their reviews, specifically the three-star ones, which tell you more than the fives. In Sunnyvale's competitive market, we've seen unlicensed operators advertising on neighborhood apps who disappear when a gate they "fixed" fails and damages a vehicle. Haven Clause 1, 3, and 4 exist because we've watched what happens when they're ignored. The documentation we provide protects both of us.

Yes, our phone is answered 24 hours a day, seven days a week. A live coordinator takes your call, assesses whether the situation is a true emergency or can be scheduled, and connects you with the local team. A gate that won't open and traps a vehicle inside your property, or a gate stuck open that compromises security, gets priority dispatch. A gate that's simply noisy or slow gets scheduled for the next available appointment. We don't charge extra for after-hours calls, but we do ask that you reserve "emergency" for situations that actually are. Call (669) 900-1904 any time.

A true emergency is a gate that poses an immediate security risk or safety hazard. Gates stuck open overnight in Sunnyvale's commercial zones along Lawrence Expressway, exposing inventory or equipment. A swing gate with a broken weld that's hanging by one hinge and could fall. A sliding gate off its track blocking a fire lane or driveway exit. A gate that won't open and has trapped a resident who needs medical access. Noisy operation, remote control failure when the keypad still works, or cosmetic rust are urgent but not emergent. We'll schedule those promptly, usually within a day or two.

For genuine emergencies, we typically have a technician to your Sunnyvale property the same day you call, often within a few hours depending on current volume and your location relative to our active jobs. Non-urgent repairs are usually scheduled within 24 to 48 hours. We don't promise impossible arrival windows; Haven Clause 2 means we give you a real schedule, a named technician, and a text when they're en route. If we say 2:00 PM, we mean 2:00 PM, not "sometime Tuesday."

Our repair warranty covers parts and labor for one year from the date of service. If a control board we installed fails eleven months later, we replace it at no charge. If a weld we made cracks, we return and fix it. The warranty is in writing on every invoice, with clear terms about what's covered and what isn't. Normal wear, damage from vehicle impact, or modifications by another contractor void coverage, which is standard and fair. Haven Clause 1 means you have this in writing before we start, not a verbal promise you can't enforce.

New installations carry a two-year warranty on our workmanship and the operator manufacturer's warranty on their equipment, typically three to five years for LiftMaster and DoorKing residential units. The gate structure itself, if we fabricated it, carries a ten-year warranty against structural failure under normal use. We document every warranty term in your job folder, including the manufacturer's claim process and our direct service number for any issue. In twelve years, we've learned that a warranty you can't find when you need it is no warranty at all. That's why we put it in writing, every time.

The Haven Standard is the five-clause framework every Vance Gate Repair branch works to. Clause 1: Have it in writing, flat price and scope before work starts. Clause 2: Arrive on schedule, with a named tech and a text when they're en route. Clause 3: Verified crews, licensed and insured, with numbers you can check. Clause 4: Evidence on every job, photos and readings of what we found. Clause 5: No surprises, no upsell, no scope creep. Adrian Vance built this system in 2014 after watching homeowners pay twice for the same problem because no one documented the first repair. It's stamped on every page we produce because it's how we work, not just what we say.

Call us. If the gate isn't operating as quoted, or if something we did isn't right, we return and make it right at no additional charge. We don't hide behind fine print or make you prove we were at fault. Haven Clause 5 is "No surprises," and that includes the surprise of discovering we don't stand behind our work. Our reputation in Sunnyvale, Santa Clara, and Cupertino depends on solving problems, not creating new ones. If we missed something, we want to know, and we want to fix it. That's the only way the 22,000+ gate count means anything.

Our repair and installation warranties are tied to the property and transfer to the new owner automatically. When you sell, leave your documentation folder, the wiring diagrams, and the photographed limit-switch settings for the next homeowner. They'll know exactly what was done, when, and by whom. In Sunnyvale's active real estate market, where homes in West Valley or Lakewood often sell within days of listing, this documentation is a genuine selling point. Buyers and inspectors appreciate a gate system with a clear maintenance history. We've had new owners call us directly, folder in hand, to continue service where the previous owner left off.
