Fix garage door sensor — Sunnyvale, CA
Last updated: September 24, 2026
What affects the price
When you call for a quote, the final number depends on a few specific factors. First, we need to know the extent of the damage—is it a simple spring replacement or a full door replacement? The materials you choose, like steel versus wood, and the complexity of the hardware or opener system, will also shift the total. If parts are specialized or if the track needs significant realignment, that impacts labor hours. We evaluate your specific setup to provide an accurate estimate. Exact pricing confirmed free on the call.
About this service
Safety sensors are the small photo-eye units located near the ground on both sides of the door. If they are misaligned, dirty, or damaged, the door will refuse to close as a safety precaution. We troubleshoot the wiring and realign the lenses to ensure the system functions reliably. The cost is typically a standard service call fee unless replacement parts are needed, with exact pricing confirmed free on the call.
