Squeaking, Grinding or Banging? What Your Garage Door's Noise Means

Question 01

What is my garage door noise telling me?

Each noise points to a different part. Squeaks are usually dry rollers or hinges. Grinding and scraping mean metal on metal, often dry or worn rollers or a track problem. Rattles are usually loose bolts. Pops and bangs point to springs or cables. Chamberlain, the opener maker, says some noise can't be avoided on the largest door in the home.

What matters is a sound that's new, or one that's getting louder. Find yours in the table and do the safe thing in the third column. If the last column says repair, stop there.

Anything marked repair needs a technician. Thom does garage door repairs right across the Sunshine Coast.

Question 02

Why is my garage door squeaking when it opens?

Usually because the rollers and hinges have dried out. B&D, an Australian door maker, says squeaking often points to rusty springs or hinges that need lubrication, and a good silicone spray can often quiet it. If the squeak comes back after that, B&D's advice is to book a professional service.

Start with a clean. B&D suggests washing the door with water, a soft cloth and a brush before you reach for any spray. Dirt in the tracks and rollers only makes things worse.

Then go light. B&D says to use a silicone spray only and avoid grease. Do the rollers first, then a light coat on the tracks, then a little on the hinges. B&D warns that too much spray builds up dirt, so wipe off the extra. Switch the opener back on and run the door a few times.

Salt air near the beach is hard on these parts. The salt air and rust guide covers which products suit a coastal door and how to slow rust down.

Question 03

What does a grinding or scraping noise mean?

It means metal is rubbing on metal, or the door is catching as it moves. B&D lists dry parts, worn rollers, tracks out of line, loose hardware, bent tracks and rubbish in the track. Merlin, an opener brand, tells owners to stop using the door as soon as they hear grinding or scraping.

Stones and leaves in the track are the easy ones. With the door shut, clear them out and wipe the track with a soft cloth. Steel-Line points out that nylon rollers can crack and chip, and steel ones can bend.

A bent track or a chewed-up roller isn't a DIY fix. Don't try to bend a track back into shape. The whole door rides in it, and the springs and cables are working the entire time. Thom replaces worn rollers and bent track as part of garage door repairs.

Question 04

What does a pop or a loud bang from my garage door mean?

A pop as the door moves can mean a torsion spring is failing. One loud bang usually means a spring or a cable has broken. B&D says a snapping spring often sounds like a firecracker or a gunshot, and that torsion springs are under so much tension you shouldn't inspect or fix them yourself. Stop using the door and call.

The broken spring guide covers what to do while you wait. For the fix itself, Thom does spring repairs across the Sunshine Coast.

A bang every time the door runs is a different story. B&D says it can be loose panels knocking together on a sectional door, or a door that's out of balance. An unbalanced door puts extra strain on the opener and wears parts out early. Get it checked before that happens.

Question 05

Why does my garage door rattle?

Loose hardware, most of the time. B&D says rattling often means nuts, bolts or screws on the door or tracks have come loose, and warns that leaving it can pull the door out of line. Gliderol, another Australian door maker, says bolts and fixings can work loose over time, and to check the track brackets.

With the door shut, you can tighten loose bolts you can see on the track brackets and hinges. Just make them firm. Steel-Line warns against over-tightening.

Question 06

Why is my garage door opener so loud?

First, work out whether it's the door or the opener. Chamberlain suggests closing the door, pulling the manual release and moving the door by hand. It should move smoothly and feel balanced. If it's quiet by hand but loud under power, the noise is most likely coming from the opener or its chain or belt.

Not sure where the release is, or how to hook the door back onto the opener after? The manual release guide walks through it.

Leave the opener's chain or belt alone unless its manual tells you how to oil it. B&D warns that oiling it the wrong way can make the opener noisier and shorten its life.

Motor humming but the door not moving? That's covered in garage door won't open or close. If the opener itself is worn out, garage door motor replacement is the fix.

Question 07

My roller door is squeaky and noisy. How can I fix it?

Start with the guides, the channels the door runs up and down in. Gliderol says to keep them clean by wiping the inside with a rag, and to use only silicone spray there, never oil, grease or other petroleum products. Steel-Line adds that on a roller door, the shinier the tracks, the better it runs.

A roller door's springs sit inside the drum at the top. Gliderol says a roller door that's hard to lift, or drops as it closes, may need its spring tension adjusted, and that's a job for a technician. Heavy roller door and spring tension explains what's going on.

Near the beach, salt and sand build up in roller door guides. A wipe-out now and then, plus a regular garage door service, helps keep the door quiet.

Question 08

When does a noise mean it's time for a service?

When a squeak comes back soon after a clean and a spray, or when the door starts to rattle or sound different from how it used to. A service catches small problems early, before they wear out other parts. Grinding, scraping, pops and bangs are different. Stop using the door and call.

Every service Thom does covers the same five checks: spring tension and balance, roller and track lubrication, hardware tightening, a look at the cables and drums, and a test of the opener and its safety reversal. Then he runs the door by hand and under power to check it's quiet and even.

How often to book depends on how much the door runs and how close you are to the beach. Garage door servicing sets out the intervals. Repairs and servicing are booked as a callout valued between $200 and $300 depending on the door size and the labour involved. The service and repair costs guide explains what the callout covers.

Thom services doors right across the Sunshine Coast, including Mooloolaba and Alexandra Headland, 6am to 6pm, seven days. Call 0402 882 653 or book a callout, and mention the noise you're hearing.
