Sliding Window Making Noise? Causes & Repair Cost

The sound a sliding window makes as it moves usually tells you which part has worn.

The short answer

A sliding window that screeches, grinds or knocks as it moves usually has worn rollers. A dirty or dented track makes a rough scraping sound instead. If the glass clatters as the shutter moves, the rubber holding it has usually shrunk. Each sound points to a different repair.

The useful distinction

Listen for wheels, track or loose glass

A regular knock that repeats with wheel rotation points to rollers. A scrape that changes at one place belongs to the track or guides. A light clatter from higher in the shutter usually means the glass rubber has shrunk.

Why it happens

Usually one of these 6 things, commonest first. Each one says how to tell, and what we do about it.

  1. Worn rollers screech or knock under an aluminium shutter

    How to tell
    Rollers are the small wheels under the shutter. A high screech means one has stopped turning and is skidding. A soft knock that repeats as you slide means one has worn flat on one side.
    What we do
    We fit a new pair of rollers sized to the shutter. We clean the track first, so old grit does not wear the new pair. The window then slides quietly.

  2. Worn rollers rumble under a heavy uPVC shutter

    How to tell
    A uPVC slider with tired rollers makes a low rumble as it moves. You may also hear the interlock scrape as it closes. The interlock is the edge where the two shutters meet.
    What we do
    We fit rollers matched to your uPVC window system and set the shutter height. At the right height, the interlock meets without scraping.

  3. Grit in the track or worn guides are scraping

    How to tell
    A gritty crunch along the whole track points to packed dirt. A scrape along one side points to worn guides, the parts that keep the shutter straight. A click at the same spot is often a dent in the track.
    What we do
    One repair visit covers the track, the guides and the alignment. We clean the track, smooth a rough spot and reset the guides. Many noisy windows need no new part at all.

  4. The glass clatters because its rubber has shrunk

    How to tell
    The noise comes from the glass, not from the track. It buzzes or clatters as the shutter moves or meets the frame. The rubber at the corners of the glass may show gaps.
    What we do
    We fit new glazing rubber, the strip that holds the glass firm, all round the pane. The glass then sits still while the shutter moves.

  5. The noise comes from more than one place on an aluminium window

    How to tell
    You hear a scrape low down and a rattle higher up. Cleaning the track helped for a few days only.
    What we do
    One aluminium window repair visit covers the full window. We clean and dress the track, check each roller and tighten loose fittings. Any worn part is priced on its own line before we change it.

  6. Metal is grinding on metal because the window is worn out

    How to tell
    The sound is a scrape or a grind, not a squeak. You can see bright bare metal along the track or on the bottom of the shutter. The window is many years old and has been repaired before.
    What we do
    Once the track and the shutter have worn into each other, new rollers only hide it for a while. We fit a new aluminium sliding window in the same opening, and take the old one away.

What you can check first

These checks are safe to do yourself. A photo or a short video of what you find helps us come prepared.

  • Slide the shutter slowly and listen for where the sound comes from: underneath, the side or the glass.
  • Notice whether the sound repeats evenly along the track or happens at one spot.
  • Look at the rubber around the glass for gaps, cracks or missing pieces.
  • Vacuum loose grit out of the track, then slide the shutter again and listen.
  • Do not spray oil on the rollers or the track to quieten them.

Common questions

Is a noisy sliding window a sign that a part is failing?

Often, yes, when the noise is a screech or a grind. A roller that has stopped turning scrapes the track on every slide. Left alone, it wears the track too, which costs more to put right.

Why did my sliding window get noisy after the rains?

Rain water that sits in the track can rust steel rollers. Wet dust also packs into the track and dries hard. We clear the drain holes in the track during a roller job, so water can run out.

Can a recording of the noise help you find the fault?

Yes, a short video with sound helps a lot. A screech, a knock and a clatter each point to a different part. We still check the window on the visit before we change anything.
