Garage door sensors — Cambridge, MA

Last updated: September 24, 2026

What affects the price

Figuring out what a garage door repair will run depends on a few specific variables. The main factor is whether the issue is mechanical—like a broken spring, frayed cable, or a faulty motor—or if the door panels themselves are damaged. Parts quality and the size or weight of your door also play a role in the total. We don't guess over the internet; a technician assesses your specific setup to provide an exact pricing confirmed free on the call.

About this service

Safety sensors are required on all modern garage doors to prevent the door from closing on people, pets, or objects. If your door hits the floor and immediately reverses, or if it won't move at all, the sensors are the first thing to check. We test the signal integrity and ensure the mounting hardware is secure so your door operates safely. If they have failed due to age or water damage, we provide replacements. Exact pricing confirmed free on the call.
