Average Cost to Repair or Replace Garage Door Sensors

Having working garage door sensors is crucial for the safe and proper operation of your garage door. These sensors detect when something is blocking the path of the door, signaling it to stop closing and reverse direction to open again. This prevents potential damage or injury from the door trying to force itself shut on an obstruction. If your garage door sensors are malfunctioning or broken, you’ll want to get them repaired or replaced as soon as possible. But what is the average cost for this repair or replacement?

Repair Cost

If your garage door sensors are still intact but not working properly, you may be able to get away with just repairing them. The average cost to repair garage door sensors is $100 to $150. The repair may involve adjusting or tightening wiring connections, replacing batteries, or cleaning and troubleshooting the sensors and wiring to pinpoint the exact problem. Simple fixes like these can sometimes get your sensors fully functional again.

Replacement Cost

If the sensors are too damaged or faulty to be repaired, they will need to be replaced completely. The average cost to replace garage door sensors is $150 to $250. The replacement process involves:

  • Removing the old sensor hardware
  • Installing new sensors and wiring
  • Aligning, adjusting and testing the sensors
  • Making sure the sensors sync properly with the garage door opener

Keep in mind that costs for both repairs and replacements can vary based on your location, the company doing the work, the extent of the issues with your sensors, and whether any other parts need replacement. Contact a professional garage door company to get an exact quote for your specific situation.

Extra Costs

Some additional costs to keep in mind beyond the basic repair or replacement:

  • Service call fee – $50 to $100 fee just for the technician to come assess the problem.
  • Additional sensor replacement – If both your sensors need replacement, it may cost double for parts and labor.
  • Removal of old sensors – This add-on service could cost an additional $25 to $50 depending on difficulty.
  • NEW opener installation – Worst case, the issues may point to a problem with your opener, which costs $500 to $1000+ to replace.

Preventing issues with your garage door sensors through regular maintenance and testing can help you avoid unexpected repair and replacement costs down the road. But even with proper care, sensors may eventually fail. Knowing the average cost to repair or replace them can help you budget and take action when problems pop up. Regular sensor checks, quick fixes to issues, and timely replacement when needed will ensure safe, uninterrupted access to your garage.
