When You Need Automatic Gate Repair
Electric Gate Repair systems in Sunnyvale face specific challenges, including moisture-related corrosion from the Bay and wear on older gear assemblies. We see these systems fail in predictable ways. If you notice any of the following, your gate likely requires a professional inspection:
- Photo-eye failure: The gate reverses unexpectedly or will not close. This often happens when the infrared beam (the safety sensor) is misaligned by even an inch or when the lens is clouded by dust or moisture.
- Limit switch issues: The gate travels too far, hitting the catch post or the ground. This indicates the internal limit switch-the component that tells the motor where to stop-has slipped or failed.
- Grinding or screeching noises: This usually points to a failing gear box or a lack of lubrication in the main drive assembly. If left unaddressed, this can lead to motor burnout.
- Electrical or control board faults: The gate remains unresponsive to remotes or keypads. In older systems, we often find that the circuit board has suffered moisture damage or has been tripped by a power surge.
- Chain or belt tension problems: The chain is sagging or the belt is slipping, causing jerky movement. We see this often in Sunnyvale properties with high-traffic commercial-grade openers.
Safety Warning: Automatic gate systems involve high-voltage wiring (often 120V) and high-tension chains or belts that can cause serious injury if mishandled. Do not attempt to adjust the motor limits or open the control box if you are not trained in electrical safety. If your gate is stuck in an unsafe position, call (669) 900-1904 for immediate assistance from a trained technician.
Our Automatic Gate Repair Process

We believe that a repair is only as good as the record left behind. Our process is designed to ensure you understand exactly what happened to your gate and what we did to fix it. We follow these steps on every job:
- System Diagnostic: We test the motor, the logic board, and the safety devices. We identify the root cause rather than just treating the symptom.
- Written Scope and Price: Under Clause 1 of the Haven Standard, we provide a written price before any work starts. There are no surprises and no “call for pricing” after the fact.
- The Repair: We perform the necessary work, whether that is soldering a new relay on a circuit board, replacing a worn gear, or realigning a photo-eye. We work on all major brands, including LiftMaster, DoorKing, and Elite.
- Photo Documentation: Under Clause 4 (Evidence on every job), we provide a documented photo record of every adjustment. We show you what we found, what we replaced, and how the new settings look.
- 365-Day Done Right Promise: We stand by our work. If the repair is not right, we make it right within one year at no additional charge.

FAQs - Automatic Gate Repair

How quickly can you fix my gate in Sunnyvale?
We prioritize urgent repairs and often provide same-day service for critical gate failures. Because we are locally based, we can dispatch a technician to most parts of Sunnyvale efficiently. Call (669) 900-1904 to check our current schedule.
Is it cheaper to repair my gate motor or replace it?
In many cases, repairing the existing motor is the more cost-effective choice, especially if the motor is a high-quality unit from a brand like FAAC, BFT, or Viking. We only recommend replacement if the cost of parts and labor exceeds the value of a new unit or if the motor is obsolete. We provide a written analysis of the repair versus replacement cost before you make any decisions.
Do you work on my specific gate brand?
Yes, we service nine major automation brands, including LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Our technicians are trained on the specific wiring diagrams and board layouts for these manufacturers, which is why we can provide a documented photo record of our work on every visit.
Why does my gate move slowly or stop halfway?
This is often a sign of a failing capacitor, a Gate Realignment issue, or a restriction in the gate track. If the capacitor is failing, the motor lacks the starting torque to move the gate efficiently. If the track is dirty or the wheels are worn, the motor hits an obstruction sensor and stops for safety. We diagnose these issues by checking the current draw on the motor and inspecting the physical path of the gate.
If you have questions about your specific gate system, call (669) 900-1904. We are available 24/7 to discuss your repair needs and provide a clear, written estimate for the work required. Our team is ready to assist you with any Gate Repair in Sunnyvale needs you may have, ensuring your property remains secure and accessible.
