To fix a loose aluminium window handle, prise off the cover caps, tighten the two fixing screws and test the handle. If it spins freely or will not lock after tightening, the spindle or gearbox is worn and the handle should be replaced with one that matches the spindle length and screw centres. Door and window handles are things we use every day to enter and exit our homes or let some fresh air in. Unfortunately, this constant use can cause wear and tear, eventually leading to permanent damage.
Having a loose or broken window handle can be a pain. You'll probably still be able to open and close your window unless your locking mechanism is jammed, but you probably won't be able to secure it, so if a strong gust of wind comes along, it will blow open. This is why we put this piece together, explaining how to fix an aluminium window handle.

How Do You Fix a Loose Aluminium Window Handle?
Most loose aluminium window handles just need their two fixing screws tightening. Turn the handle to the open position, prise off the cover caps, tighten the top and bottom screws firmly without overtightening, then refit the caps and test the handle. The job takes around five minutes with a screwdriver.
If your aluminium window handles don't need to be replaced and only need to be tightened, follow the steps below to tighten them.
Step 1: Remove the Screw Cover Caps
Before you can start adjusting anything about your window handles, you will need the right tools, including a screwdriver and, where required, an Allen key, to remove the plastic caps covering the two screws at the top and bottom of the handle. You can do this with a flathead screwdriver or your fingernail if you can.
You might need to set the handle to the open position to gain access to the bottom screw, so do this now before you make any further adjustments. Also, note the handle position before adjusting it so you can return it to the correct position later.
Step 2: Tighten the Top Screw
Once you've removed the plastic cap on the top screw, you can tighten it with your screwdriver. Be wary of making it too tight and stripping the screw; if the area looks corroded or the handle is still hard to turn after tightening, the problem may be inside the mechanism rather than just a loose fixing.
Step 3: Tighten the Bottom Screw
Now you can adjust the bottom screw in a similar fashion while also being careful not to strip the screw. If that does not help, the internal parts may be worn and simple tightening will not fix the handle.
Step 4: Refit the Caps and Test the Handle
After you've tightened both screws, you can replace the plastic caps, and your aluminium window handle should now operate as normal; then test it by opening and closing the window to check that it moves smoothly and feels secure.
How Do You Replace an Aluminium Window Handle?
Remove the cover caps, undo the bottom then top screw and pull the handle and spindle out. Measure the spindle length and screw centres (43mm is most common), buy a matching handle in the correct hand for tilt and turn windows, then fit it, screw it in and test the lock through its full movement.
If the handle of your aluminium window is beyond repair, then it might be a better idea to replace your window handle entirely. In many cases, this is a straightforward DIY job, although the difficulty depends on the handle type and choosing the correct replacement.
Step 1: Remove the Cover Caps
Once again, before adjusting or replacing any part of your window handle, you'll need to remove the plastic caps covering the screws at the top and bottom of your handle.
You can do this with a flathead screwdriver, a fingernail, or any other tool that can lift the plastic caps without damaging them.
Step 2: Undo the Bottom Screw
Once you've removed the plastic caps and gained access to the two screws, you should start by unscrewing the bottom screw. This will prevent the handle from becoming loose and swinging.
Step 3: Undo the Top Screw and Remove the Handle
Unscrew the top screw and remove the handle from your window frame. If the old handle was spinning freely before removal, that usually points to a stripped spindle.
Step 4: Measure the Spindle and Fit the New Handle
Now that you've removed your old window handle, replacing an aluminium window handle usually takes 10-15 minutes.
Before you install the new handle, measure the spindle and screw spacing on the old handle instead of making a guess. Common spindle sizes are 7mm and 8mm, and screw spacing is usually 43mm or 50mm. Check these measurements carefully when choosing replacement handles. Tilt & turn handles are side-specific, so pick the correct left- or right-hand version for the spindle to fit and operate properly. Start with the top screw and line up the hole in the handle with the hole in the window frame. You can either drill or screw the top screw in. Just be careful not to tighten it too much, as you'll end up stripping the screw. A replacement aluminium window handle usually costs between about £10 and £40, so verify the exact sizes before you buy.
Step 5: Secure the Bottom Screw
When the top screw has been tightened, line up the bottom hole of the window handle with the bottom hole of the window frame. On some aluminium windows, the lock connection must line up properly with the spindle so the handle can secure the sash. You can then either drill or screw the bottom screw in.
Step 6: Test the Handle and Refit the Caps
Once both screws have been adequately tightened, test the handle through its full movement to confirm the installation is secure and that the window handle is functioning correctly before you replace the plastic caps that cover the screws, either with the plastic caps from your old handle or new ones if they come with your new window handle. If the old cover plate looked bad, replacing it or fitting the new caps neatly improves the finish. Proper installation also helps improve security and extend the life of the handle. In many cases, replacing just the handle solves the issue without changing the whole window fitting.
Aluminium Window Handle FAQs
Are timber windows cheaper than aluminium windows?
Yes, timber windows are often cheaper than aluminium windows; however, there are good reasons for this, as aluminium windows are much stronger than timber windows, as they will dent or bend if they are damaged, unlike timber window frames that will crack or splinter.
Aluminium windows also don't ever need to be varnished or painted, especially if they have a powder coating, so while timber window frames are cheaper, they aren't always the best option.
Can window hinges be repaired?
Yes, window hinges can be repaired quite easily if you have some experience with DIY projects, but if you don't, it would be a good idea to get a professional in. If the issue affects the locking point or the outside security of the window, or the repair starts to feel too difficult, a professional should inspect it. If you are unsure about the correct replacement, a local shop can sometimes match the old handle for you.
How do you measure the spindle length on a window handle?
Remove the handle and measure the spindle from the flat underside of the handle base, where it sits against the frame, to the tip. Common lengths are 30mm, 35mm and 40mm. Too short and it will not engage the gearbox; too long and the handle will not sit flush. Measure the distance between the two screw holes (the screw centres) at the same time.
Can I use a uPVC window handle on an aluminium window?
Often, yes. Many aluminium casement windows use the same espagnolette-style handles as uPVC windows, with a 7mm square spindle and 43mm screw centres. Check the spindle length, screw centres and handing before buying, as tilt and turn handles and some older aluminium systems use different patterns. Our guide to the different types of aluminium windows explains the main opening styles.
How do you open a locked window handle if you have lost the key?
Many locking window handles use a common key, so a replacement from a hardware shop or locksmith often fits. If not, a locksmith can open the handle without damaging the frame. Avoid forcing the handle, as this can snap the spindle or damage the gearbox, turning a cheap fix into a more costly repair.
What if the window still lets in draughts after fixing the handle?
If the handle is secure but the sash still does not close tightly, the gaskets, hinges or keeps may need attention. Follow our guide to draught proofing aluminium windows, and if water is getting in, see how to stop water leaking from aluminium windows.
