Repair or Replace?
Most garage doors that won't close can be repaired quickly and affordably. The majority of these issues are caused by sensors, limit switches, or minor electronic faults—all of which are fixable. We'll always give you honest advice if replacement is the better option.
Usually a Repair if:
- The issue started suddenly
- Only closing is affected (opening works fine)
- Your door is under 15 years old

Frequently Asked Questions
Why does my garage door start closing then reverse immediately?
This is the classic symptom of misaligned safety sensors. The infrared sensors on either side of the door frame must have a clear line of sight to each other. If they're knocked out of alignment, dirty, or blocked by debris, the system thinks there's an obstruction and reverses the door for safety. Try cleaning the sensor lenses with a soft cloth and checking they're pointing directly at each other.
What does it mean when my garage door stops halfway and won't close further?
This usually points to either a track obstruction, worn rollers causing friction, or incorrect travel limit settings on the motor. The door's safety mechanism kicks in when it detects resistance. Check the tracks for debris, damage, or bent sections. If the tracks look clear, the motor's down-limit switch may need adjusting—this tells the motor how far to travel before stopping.
Why does my garage door close then immediately open again?
This frustrating issue is typically caused by the motor's up-limit switch being set incorrectly. When the door closes, the motor thinks it's hit an obstruction and reverses. This can also happen if the close-force setting is too sensitive. Both are adjustable settings on the motor unit, but we recommend having a professional adjust them as incorrect settings can create genuine safety issues.
Can I fix a garage door that won't close myself?
For sensor issues, absolutely—try cleaning the sensor lenses and realigning them so they face each other perfectly. You'll usually see a small LED light on each sensor that should be solid (not blinking) when aligned. For anything involving the motor, limit switches, control board, or springs, we strongly recommend calling a professional. These components involve electrical systems and high tension mechanisms that can cause injury if handled incorrectly.
How much does it cost to fix a garage door that won't close?
Simple fixes like sensor realignment typically cost £50–£80 for the callout and labour. If it requires a new sensor, control board, or motor adjustment, expect £120–£250 depending on the parts needed. We provide a fixed quote before starting any work, and most repairs are completed in a single visit.
Is this a safety issue I should address urgently?
Yes—a garage door that won't close properly leaves your home unsecured and vulnerable. Additionally, if the sensors are faulty or bypassed, the door may not detect genuine obstructions (like a child or pet), which poses a serious safety risk. We offer same-day repairs across our service areas and can usually get to you within a few hours of your call.
How long does a repair take?
Sensor adjustments take 10–20 minutes. Limit switch adjustments take 20–30 minutes. Component replacements (sensors, control board) typically take 30–60 minutes. We carry common parts on the van to avoid delays, so most repairs are completed in one visit.
