Fixing Sliding Aluminum Windows: A Comprehensive Guide

The majority of the windows have aluminum frames around the glass, and they roll along an integrated track on tiny plastic wheels. Rust accumulation and wear over time can cause the wheels to seize up. In addition to making the window difficult to open and close, this can also cause the track to become worn out to the point where the window no longer opens or, worse yet, falls out totally if the broken wheels are not replaced.

Here, we demonstrate a quick fix for this problem that should endure for years at a fraction of the price of replacing the window.


The majority of these sliding window designs lift out. If it doesn’t lift out, look for tiny locking lugs at the top on either side that should unscrew, allowing you to lift and pull the object out.

Turn the window upside-down slowly to inspect the tiny nylon plastic wheels. It’s likely that your windows are cracked or clogged with gunk if they haven’t been sliding smoothly.

Then, take a look at the window sill’s real metal track. It’s probably filthy. But more importantly, look for damage and “flat spots”.

These nylon or plastic wheels, which enable the window to roll open and shut, are reasonably priced and incredibly simple to replace. Finding the right size can be the most difficult part. The LEFT and RIGHT wheels, which typically mirror images of one another and move to either end of the window, should be noted.

TIP: Occasionally, spare wheels will be fastened to the tops of the windows. Look at this quickly!

Utilizing a flathead screwdriver, unscrew the old wheels and then lever them out. Use a brush to scrub the window’s bottom thoroughly. Install the replacement wheels while paying attention to the Left and Right positions.


We may now get ready to put in the new window track.

Take a brush and a vacuum and thoroughly clean the entire track area.

The old track should be measured. It’s acceptable if your new track is a fraction of an inch shorter; in fact, it will make installation simpler.

Your measurement should be transferred to the new track section. Cut the track to the proper length using a hacksaw. To smooth the edges of your cut, use a file. With that, we can begin installing.

Install the new window track

Run a thin bead of silicone along the whole length of the bottom of the new track using a caulk gun or silicone in a tube.

Grab your track, loop one end over the old, damaged track, and take care not to bend it. Gently press down on the new track as you lower it until the entire length is covered by the old track. Make sure the space at either end is uniform after it is down.

Enjoy smooth sliding window operation

Make the mess clean, start the kettle, and unwind. If you continue the habit of the occasional vacuum clean and lift the window off for a check at the first sign of the wheels growing stiff, you should not have any more trouble with that annoying stuck sliding window for a number of years.
