No guessing, no unnecessary charges. Sunline Garage Doors provides honest diagnosis and same-day repair across Anaheim and Orange County.

What's Your Garage Door Doing?

My Garage Door Won't Open

This is the most common call we get. If your door won't budge or only lifts a few inches and stops, the most likely cause is a broken spring. The spring is what does the heavy lifting — without it, your opener can't raise the door on its own. Other possible causes include a disconnected trolley, a dead opener motor, or a stripped gear inside the opener. Send us a photo of the spring area above your door and we can usually tell you right away.

My Garage Door Won't Close

If your door goes up fine but won't come back down, or reverses immediately after touching the floor, the issue is usually your safety sensors. These are the small sensors at the bottom of the door tracks on each side. If they're misaligned, dirty, or blocked by something, the door thinks there's an obstruction and refuses to close. It could also be a force setting issue on the opener. This is often a quick fix.Free estimates with no pressure. We send you photos and explain what's going on before any work starts.

My Garage Door Is Making Noise

Grinding, squealing, rattling, popping, or scraping — none of these are normal. A noisy garage door usually means worn rollers that need replacing, dry hinges and hardware that need lubrication, a chain drive opener that's loosened over time, or in some cases a spring that's close to failing. The type of noise tells us a lot. If you can send us a short video with the sound, we can often diagnose it without a visit.

My Garage Door Opens Crooked or Gets Stuck

If one side of the door lifts while the other side drags, or the door jams partway up, you likely have a cable that slipped off the drum, a broken cable on one side, bent tracks, or worn rollers that are no longer sitting in the track properly. Don't keep operating the door — running it while it's crooked can make the problem worse and more expensive to fix.

My Garage Door Opener Runs But the Door Doesn't Move

If you hear the motor running but the door isn't going anywhere, the issue is usually between the opener and the door — not the opener itself. A stripped gear inside the opener, a broken belt or chain, or a disconnected trolley carriage are the most common causes. It could also be a broken spring making the door too heavy for the opener to lift. We'll check the opener and the door to find the real problem.

My Garage Door Remote or Wall Button Stopped Working

Before you assume the opener is broken, try a few things: replace the remote battery, check if the wall button works (or vice versa), and make sure the opener is plugged in and the outlet has power. If none of that works, it could be a logic board issue in the opener, a wiring problem, or the remote needs reprogramming. Contact us and describe what's happening — this is sometimes a quick fix we can walk you through over text.

Not Sure What's Wrong? Here's How We Help.

You don't need to diagnose it yourself. Here's how it works when you contact Sunline Garage Doors:

Step 1 — Tell us what's happening. Call, or text us. Describe what the door is doing in your own words. "It won't open," "it's making a loud noise," "it's stuck halfway" — that's all we need to start.

Step 2 — Send us a photo or video. A quick photo of the door, the springs, the opener, or a short video showing the problem helps us diagnose the issue before we come out. This means we show up prepared with the right parts and can give you an accurate estimate upfront.

Step 3 — We diagnose and give you an honest estimate. We'll tell you what we think is going on based on your photos. When we arrive, we confirm the diagnosis and give you a price before we start any work. No surprises.

Step 4 — We fix it. Most repairs are completed the same day in about one to two hours. After the repair, we test the door, lubricate the moving parts, and inspect the rest of the system to make sure nothing else is about to fail.

Frequently Asked Questions

Q: How do I know if my garage door spring is broken?

A: If your door won't open, feels extremely heavy, or you heard a loud bang from the garage, you probably have a broken spring. Look above the door — if you see a visible gap or separation in the metal coil, that's a snapped spring. Don't try to force the door open.

Q: Why is my garage door so loud all of a sudden?

A: Sudden noise usually means worn rollers, dry hardware, or a spring that's under stress. If it's a new grinding or scraping sound, something may have come loose or shifted. Send us a video with the sound and we can usually tell you what's going on.

Q: Can you diagnose the problem from a photo?

A: In most cases, yes. A clear photo of the spring area, the tracks, or the opener tells us a lot. A short video of the door trying to open or close is even better. This is why we ask for photos before we come out — it saves you time and lets us come prepared.

Q: How much does garage door repair cost?

A: It depends entirely on what's wrong. A sensor realignment is a quick fix. A double spring replacement is a bigger job. Rather than guess, send us photos and we'll give you an honest estimate based on your specific situation. No hidden fees.

Q: Should I try to fix my garage door myself?

A: For anything involving springs, cables, or tracks — no. These components are under extreme tension and are dangerous to work with without proper tools and training. Sensor alignment or remote reprogramming you can sometimes handle yourself, and we're happy to walk you through it over text if it's a simple fix.

Q: Do I need a new garage door or just a repair?

A: Most of the time it's a repair. Broken springs, worn cables, faulty openers — these are all fixable without replacing the whole door. We'll always recommend a repair over a replacement if the repair makes sense. We'll only suggest a new door if the damage is too extensive or the door is at the end of its lifespan.
