A garage door that won't open is more than frustrating.it's a real problem that can trap your car and derail your whole day. Before you call for a repair, there are several quick checks you can do yourself to pinpoint the issue and potentially save hundreds of dollars on unnecessary service calls.
Start with the simplest fix. Is your remote actually working? Replace the batteries in your remote control first. A dead battery is the most common reason a garage door won't respond to commands, and it costs nothing to rule out.
Next, walk to your garage door opener unit and look for a power light. If there's no light, check that the unit is plugged in and that your outlet has power. Test the outlet with another device like a lamp. If the outlet is dead, you may have tripped a circuit breaker in your electrical panel. Flip it back on and try again.
Still nothing? Check whether your door has a manual release cord hanging from the opener. Pull that cord firmly to disengage the automatic mechanism. You should then be able to lift the door by hand. If you can't lift it at all, your springs are likely broken and you'll need professional help.
Walk the length of your garage door tracks on both sides. Leaves, ice, debris, or even a small fallen object can prevent the door from rolling smoothly. Clear anything blocking the path. In Epsom's snowy winters, ice buildup in the tracks is particularly common. A plastic or wooden scraper (never metal on aluminum tracks) can help.
Check the weather stripping at the bottom of the door. If it's peeling away or damaged, it might be catching on the ground or threshold. A stuck seal can feel like the whole door is broken. You can temporarily trim it back with a utility knife as a quick test. For a permanent fix, see our guide on weather stripping and seals in Epsom to understand whether replacement is needed.
Modern garage doors have infrared sensors near the floor on each side of the opening. These sensors prevent the door from closing if anything is in the way. Dust, spider webs, or misalignment can trigger them to block operation.
Wipe both sensors clean with a soft cloth. Check that they're aligned and facing each other directly. You should see a small green light on each sensor when power is on. If one sensor is dark, it may have come loose or need repositioning. Gently adjust it until both lights are visible.

When you press the remote, does the opener motor hum or make noise? Or is it completely silent? A humming sound without movement often points to a broken spring or stripped gears inside the opener. That requires professional service.
If you hear nothing at all, power to the unit may be the issue. If the motor runs but the door doesn't budge, you're likely dealing with a spring failure. Garage door springs last 7 to 9 years with normal use, and Epsom's freeze-thaw cycles can accelerate wear. Attempting to replace a spring yourself is genuinely dangerous. The tension in these springs is extreme.
If you've checked the remote batteries, cleared the tracks, cleaned the sensors, and confirmed the opener has power, it's time to call a technician. You're likely dealing with a broken spring, damaged opener, or motor failure. Our team at Garage Door Epsom can diagnose the problem during a same-day visit and provide you with an honest cost estimate before we begin any work.
One more thing to check beforehand: if your door is stuck partway open or closed, do not force it. A stuck garage door can be a safety hazard, and forcing it may cause additional damage. Visit our garage door safety guide to understand why forcing a stuck door is risky.

Q: Why is my garage door not working after a power outage? A: After power returns, the opener may need to be reset. Most openers have a reset button on the unit itself. Press it and reprogram your remote following the manual instructions. If that fails, the power surge may have damaged the opener circuitry.
Q: How much does garage door repair cost in Epsom? A: Repair costs range from $150 for a service call and minor fix to $400 for spring replacement. A free estimate from Garage Door Epsom removes guesswork from your budget.
Q: Can I fix a stuck garage door myself? A: Simple fixes like clearing tracks or replacing remote batteries are safe DIY tasks. Spring replacement, motor repair, and sensor realignment should be handled by professionals to avoid injury or further damage.
Q: What should I do if my garage door is stuck halfway? A: Stop attempting to open or close it. Use the manual release cord if needed, then call for professional service. A halfway stuck door signals a serious issue that forced operation can worsen.
Q: How do I know if my garage door spring is broken? A: A broken spring will prevent the door from opening even if the motor runs. You may hear a loud snap or bang when the spring fails. Never attempt to replace it yourself.professional service is essential for safety.
