Maintaining a Sliding Milgard Window

In this video you’re shown how to maintain your Milgard sliding window including window cleaning and window care.  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. Putty knife
  2. Pipe cleaner
  3. A mallet and a soft block of wood
  4. Non-abrasive cloth, soap, and water
  5. Safety glasses
  6. Gloves

The first step to maintaining your sliding window is to slide open the window sash.  On the top of the window, you’ll notice a few tabs, these prevent the sash from being removed from the outside.  Next to remove the sash, be sure that the sliding window is clear of the last tab and the lock is not touching the jam.  Lift up on the sash from the bottom.  Then pull out and down to remove the sash.  You may notice that moisture and debris is present in the window track, this is normal.  Using a putty knife, lift up and remove the track.  Using a non-abrasive cloth along with soap and water, clean the track.  It is important to avoid abrasive chemicals.

To re-install the window sash on your sliding window, slide the track in the grove, sloping it away from you and press down.  Snap the track back into place using a soft block of wood and mallet.  Place the wood at an angle on the track and pound the block along the length of the window track to snap into place.  Install the sash from the top, slide it in from the bottom.  Next, you’ll need to access to the outside of the window to check and clean the weep hole cover and weep hole.  A putty knife and pipe cleaner are needed again.  Using the putty knife, remove the weep hole cover, inspect the cover to insure that the flap is moving.  Use the pipe cleaner to clear the weep hole of excess debris.  Replace the weep cover back into the weep hole.
