Some garage door problems can wait until tomorrow. This page is for the ones that can’t.
A spring snaps at ten at night and the door won’t close. Your car is trapped inside the garage and you need to get to work. The door came off its track with the garage wide open, and you can’t secure the house. These situations happen more often than you’d think, and they rarely happen at a convenient time.
Sentinel Garage Door provides emergency garage door repair across San Antonio and surrounding areas. We’re available on Sundays and holidays, and we prioritize calls where safety or home security is at stake. When you call, we answer. And in most cases, we can be there the same day.
Not every garage door problem is an emergency. A squeaky roller or a remote that needs reprogramming can wait for a regular appointment. But some situations need immediate attention because they affect your safety, your security, or your ability to go about your day. Here are the ones we treat as urgent:
An open garage at night is a security risk. Anyone can walk in, access your belongings, and potentially enter your home through the interior door. We treat these calls as high priority.
When a spring snaps, the door becomes too heavy to lift manually. If your vehicle is inside and you need it, this isn’t something that can wait until next week.
An off-track door that’s partially open can’t be closed or secured. It’s also a safety hazard because of the tension stored in the springs and cables. This needs professional handling right away.
A garage door that drops without warning usually means a cable snapped or both springs failed at once. Do not try to operate the door again. This is a serious safety issue.
If the door stopped midway on a car, a bike, or anything else, the panels and tracks may be damaged. Forcing the door from this position risks making the damage worse or causing injury.
If your situation looks like one of these, call us. We’ll let you know what to do immediately and get a technician to you as quickly as possible.
If your garage door just failed and you're waiting for help, these steps keep you safe and prevent additional damage:
Don't press the opener button, and don't try to force the door up or down by hand. Moving a broken door can bend tracks, snap cables, or cause the door to fall.
The red handle hanging from the opener rail disconnects the door from the motor. Pull it toward the door. This prevents the opener from activating accidentally through a remote, a timer, or a smart app.
If the door is stuck open and you can't close it, do what you can to block the opening. Park a car across it, move valuable items inside the house, and lock the interior door that connects the garage to your home. If the door is partially open, clamp locking pliers on the track below the lowest roller to keep it from sliding down.
Don't stand under it, lean against it, or try to push it back into place. A door with broken springs or cables is holding stored energy that can release unexpectedly.
Tell us what you observed. Did you hear a loud bang? Is a cable hanging loose? Is the door crooked or off its track? These details help us arrive with the right parts and assess safety before we start.

We carry the most common repair parts on our trucks, so most emergency jobs get completed in one visit. Here's what we fix during emergency calls:
This is the most common emergency we respond to. A snapped torsion or extension spring makes the door too heavy to lift and leaves it stuck in place. We carry a range of spring sizes and can usually complete a spring repair on the spot, including re-tensioning cables and testing the full system before we leave.
An off-track door often involves a slipped cable, a broken roller, or a loose track bracket. We secure the door, identify what caused it, fix the underlying issue, and guide the door back into the tracks. If the springs also need attention, we handle that as part of the same visit.
A broken cable makes the door unbalanced and potentially dangerous. We replace the cable, inspect the drums, and verify spring tension to make sure everything is properly balanced before testing. Learn more about our garage door cable repair service.
When the opener motor dies, the gears strip, or the logic board fails at the worst possible time, we diagnose and repair it on-site. If the opener is beyond saving, we can install a replacement the same day in most cases. See our opener repair and opener replacement pages for more details.
A car backing into the door, a storm, or a falling object can bend panels or tracks to the point where the door can't operate. Depending on the severity, we either repair the damage on-site or arrange a full door replacement if the damage is beyond repair.
Emergency garage door repair is stressful. You’re dealing with a problem you didn’t expect, at a time you didn’t plan for, and you need someone you can trust to show up and fix it properly. Here’s what we bring to every emergency call:
We actually answer the phone. When you call Sentinel, you reach a real person who understands garage doors. Not a call center, not a voicemail that gets checked Monday morning. We pick up, assess your situation, and give you a realistic timeline.
We’re available on Sundays and holidays. Garage doors don’t wait for business hours, and neither do we. If your door breaks on a Sunday morning or a holiday weekend, we’re still working.
We carry common parts on every truck. Torsion springs, extension springs, cables, rollers, opener components, and track hardware. Most emergency repairs get completed in a single visit because we don’t need to order parts and come back.
We quote before we start. Emergency doesn’t mean surprise pricing. We assess the situation, explain what needs to happen, and give you a clear price before we pick up a tool. You approve the work first. Always.
We’re local. Sentinel Garage Door is based in the northwest San Antonio area. We’re not dispatching from another city. We’re already nearby, which means faster response times for emergency calls.
We provide same-day emergency garage door repair when availability allows, including Sundays and holidays. Calls involving a door that cannot be secured, a trapped vehicle, or another safety concern are prioritized. When you call, we’ll give you a realistic response time based on our current schedule and your location in the San Antonio area.
Don’t wait for it to get worse. If your garage door is broken, stuck open, or creating a safety issue, call Sentinel Garage Door. We’re local, we answer the phone, and we prioritize emergency calls.
