Garage Door Sensor Replacement Cost

A garage door sensor is a safety device that prevents the door from closing on a person or object. If your garage door sensor is damaged or malfunctioning, it's important to replace it as soon as possible.

The cost of replacing a garage door sensor varies depending on the type of sensor, the difficulty of the installation, and the location of your home. In general, you can expect to pay between $100 and $300 for a new sensor and installation.

Types of Garage Door Sensors

There are two main types of garage door sensors: contact sensors and infrared sensors.

Contact sensors are mounted on the door frame and the door itself. When the door is closed, the sensors make contact and complete a circuit. If the door is opened, the circuit is broken and the door will not close.
Infrared sensors emit an invisible beam of light across the doorway. When the door is closed, the beam is unbroken. If the door is opened, the beam is broken and the door will not close.

Contact sensors are less expensive than infrared sensors, but they are also more susceptible to damage. Infrared sensors are more expensive, but they are more reliable and less likely to be damaged.

Difficulty of Installation

The difficulty of installing a garage door sensor depends on the type of sensor and the location of your home.

Contact sensors are relatively easy to install. They can be mounted on the door frame and the door itself with screws or adhesive tape.
Infrared sensors are more difficult to install. They need to be aligned precisely so that the beam of light is unbroken when the door is closed.

If you are not comfortable installing a garage door sensor yourself, you can hire a professional to do it for you. The cost of professional installation will vary depending on the type of sensor and the difficulty of the installation.

Location of Your Home

The location of your home can also affect the cost of replacing a garage door sensor. If you live in a remote area, you may have to pay a higher price for installation because the technician will have to travel further.

You can save money on the cost of replacing a garage door sensor by doing it yourself. However, if you are not comfortable installing the sensor yourself, you should hire a professional to do it for you.
