How to Replace Alumalite Sliding Window Rollers | DIY Guide (SKU 6008)

If your Alumalite sliding window is hard to open, noisy, or dragging along the track, there’s a good chance the rollers have reached the end of their life. The good news? Replacing them is a very achievable DIY job with basic tools and a bit of care.

In this step-by-step guide, we’ll walk you through how to replace the rollers and carriage on an old Alumalite window sash, using the correct replacement rollers (SKU 6008). This is a common repair that can save you from replacing the entire window and restore smooth operation in under an hour.

What You’ll Need

Before you start, gather the following tools:

Phillips head screwdriver (or driver with Phillips bit)
Rubber mallet or timber block
Pliers or long-nose (pointy-nose) pliers (optional, for stubborn rollers)
Silicone spray or Innox (for seized screws)

🛠 Replacement rollers:
Search SKU 6008 on our website to ensure you have the correct rollers for Alumalite windows.

Step 1: Remove the Sliding Window Sash

Start by removing the sliding sash from the window frame. Once removed, lay it flat on a stable, clean surface. This makes the job safer and helps prevent damage to the glass or frame.

Step 2: Remove the Bottom Window Rail

At each end of the bottom rail, you’ll find fixing screws that hold the frame together.

Carefully unscrew both end screws
Go gently, these screws are structural and important

Tip:
If the screws are seized or difficult to move, spray them with silicone spray or Innox and allow it to soak in. Tighten the screw slightly first, then loosen it. This helps break the bond without snapping the screw.

Step 3: Remove the Rail Carefully

Once the screws are removed, gently slide the bottom rail off the sash.

⚠️ Take care not to damage the glazing vinyl or rubber, this will be reused during reassembly.

Step 4: Install the New Rollers

With the rail removed:

Align the new rollers in the channel
Slide them into position inside the rail

Make sure the rollers sit squarely and move freely within the channel.

Step 5: Refit the Glazing Vinyl

Reinstall the glazing vinyl around the edge of the glass.

To make this easier:

Mix water with a small amount of liquid dishwashing detergent
Lightly spray along the vinyl edge

This lubrication helps the vinyl slide smoothly back into the aluminium rail.

Step 6: Reinstall the Bottom Rail

Using a rubber mallet or timber block:

Gently tap the rail back onto the glass
Work evenly along the entire rail length
Ensure the vinyl stays wrapped around the glass as the frame slides back on

Take your time here, slow and steady prevents damage.

Step 7: Secure the Frame

Once the rail is fully seated:

Reinstall the frame assembly screws into both ends of the aluminium rail
Tighten firmly, but do not overtighten

Your new rollers are now installed and ready to go.

Frequently Asked Questions - Alumalite Window Roller Replacement

What causes Alumalite sliding window rollers to fail?

Over time, dirt, corrosion, flat spots, and general wear can cause Alumalite window rollers to seize or wear unevenly. This leads to windows becoming stiff, noisy, or difficult to slide.

How do I know if my Alumalite window rollers need replacing?

Common signs include:

The window dragging along the track
Grinding or squeaking noises
The sash dropping or sitting unevenly
The window requiring force to open or close

If you notice any of these, worn rollers are often the culprit.

What rollers do I need for an old Alumalite sliding window?

Most older Alumalite sliding windows use roller SKU 6008. You can locate these by searching SKU 6008 or Alumalite rollers directly on our website.

Can I replace Alumalite window rollers myself?

Yes. Replacing rollers on an Alumalite window sash is a DIY-friendly job if you have basic tools and follow the correct steps. Removing the sash and working on a flat surface makes the process much easier and safer.

Do I need to remove the glass to change the rollers?

No, the glass does not need to be removed. The rollers are accessed by removing the bottom rail of the sash while the glass remains in place.

Why should I use detergent and water on the glazing vinyl?

A light spray of water mixed with dishwashing detergent helps the glazing vinyl slide smoothly back into the aluminium rail. This reduces friction and lowers the risk of damaging the vinyl during reinstallation.

What if the screws holding the window rail are seized?

If the screws are tight or seized:

Spray them with silicone spray
Allow time for it to soak in
Slightly tighten the screw first, then loosen it

This method helps prevent stripping or snapping the screw.
