How To Adjust Milgard Sliding Window Rollers

In this video you’re shown how to adjust and clean the rollers on your Milgard windows to keep them operating smoothly.  You should have a basic understanding of simple hand tools to undertake this project.  Remember to wear eye protection and keep pets and small children out of the area when performing this process.

The tools required for this project include:

  1. Flathead screwdriver
  2. Silicone spray
  3. Paper towel
  4. Safety glasses
  5. Gloves

Occasionally, adjustment may be needed to maintain smooth window operation with your Milgard Vinyl Windows.  On the bottom of your window there are two assemblies containing vinyl wheels.  Each assembly has two positions for each wheel.  Using a flathead screwdriver, remove the wheel by snapping it out of the wheel casing.  Raise on lower the wheels to the desired height position and snap the back into place.  Repeat this step on the other wheel assembly.

Once the wheels are snapped back into place, clean your window rollers.  Make sure the wheels roll back and forth and the there’s no dirt or debris in them.  Spray your wheels with a small amount of silicone spray.  Just a quick shot for each one.  Then take a paper towel and wipe down the rollers to insure there’s no excess silicone.  To re-install the window sash, start with the top, slide into place from the bottom, then slide the window back and forth.
