Garage Door Won't Open? Troubleshoot Before You Call in South Houston
2026-06-13 7 min read
A customer called last Tuesday morning saying her garage door wouldn't open, and she was already late for work. Before we rolled the truck, I walked her through three quick checks over the phone. One of them fixed it. That's the honest approach I take: help you troubleshoot first, then schedule repair if you need it. If your garage door is stuck or not working in South Houston, here's what you should know.
Check These Things First
Your garage door might not be broken at all. Start simple.
Look at the remote batteries. Sounds obvious, but weak batteries are the number one reason a door won't open. Replace them and try again. If that works, you saved yourself a service call.
Check the wall button. Press it firmly and hold for a second. If the door opens from the wall button but not the remote, the remote needs new batteries or the receiver is failing. If neither works, move to the next step.
Look at the safety sensors. Walk along the bottom of your garage door opening. You'll see two small photo eyes, one on each side, usually 6 inches up from the ground. If either sensor is blocked by dust, cobwebs, or misaligned, the door won't close as a safety measure. Some doors also won't open if sensors are broken. Clean them gently with a soft cloth. Make sure both sensors have a clear line of sight.
Test the door by hand. Unplug the opener from the wall outlet. Try to lift the door manually. A working door should glide up smoothly with minimal effort. If it's heavy, stuck, or makes grinding sounds, you have a mechanical problem. That's when you call us.
When Your Garage Door Is Actually Broken
Not every stuck or not working door is a quick fix. If you've checked the items above and the door still won't budge, one of these issues is likely the cause.
Broken springs. Garage door springs last 7 to 9 years in South Houston's humid climate. When they snap, the door becomes extremely heavy and won't open, even with the motor running. You'll hear a loud bang if a spring breaks. Never try to force a broken spring door open; you risk serious injury. This is the most common repair we handle, and it's worth the investment because springs are critical safety components.
Damaged or derailed tracks. If the door moves partway then stops, or if you hear grinding metal sounds, the tracks might be bent or the rollers jumped the track. This usually requires professional adjustment or replacement.
Opener motor failure. If the remote and wall button both fail, and the safety sensors are clear, your opener motor may be dying. See our guide on whether your garage door opener needs replacement in South Houston for more detail.

What Repair Costs Look Like
Honest answer: it depends on what's broken. A safety sensor cleaning or battery replacement is free if you do it yourself. A spring replacement typically runs $200 to $400 per spring, depending on the door size and spring type. Opener repairs range from $150 to $600.

Frequently Asked Questions
Why won't my garage door open but the light comes on? The opener motor is likely running, but the door isn't moving. This usually means broken springs, a snapped cable, or a derailed track. The motor is working; something mechanical is preventing motion. Have it inspected professionally.
How do I know if my garage door sensors are broken? If the door closes partway then reverses, or won't close at all, the sensors may be misaligned or dirty. Clean them first. If the issue persists, the sensors need replacement, which typically costs $100 to $200.
Can I use my garage door if one spring is broken? No. A broken spring makes the door extremely heavy and unsafe to operate. The motor can't lift it properly, and manual operation risks crushing injury. Don't use the door until the spring is replaced.
How long does a garage door repair usually take? Most repairs take 30 minutes to 2 hours. Spring replacement and opener repair are typically fastest. If tracks are damaged, the job may take longer. We'll give you a time estimate when you call.
Is it cheaper to repair or replace my garage door? Repair is almost always cheaper unless the door is over 15 years old and needs multiple fixes. A new door runs $800 to $3,500. If your repair is under $400, repair makes sense. We'll advise you honestly either way.
