Fix a Stuck Window

 

Reasons for a Stuck Window

Fixing a stuck window is not difficult as windows can become stuck for different reasons:

  • Timber framed windows may warp in wet, humid conditions.
  • A stuck window can become difficult to open from a build-up of dirt or too many layers of paint applied over many years.
  • Check around the window, both inside and outside the house to see if there is any obvious cause for the window sticking.

For example, is there a nail or screw driven into the window frame or a lock stopping the window from opening?   All that may be required is to remove these and the window will open.

How to open a stuck window

Method 1

  • Use a utility knife or paint scraper and run the edge of the blade around the edge of the window and window frame, inside and outside the window.
  • Check if the window now opens.

Method 2

  • Take a hammer and small block of wood.
  • Lay the wood against the window frame and with the hammer GENTLY tap the wood around the window frame to free up the window.
  • Check to see if the window opens.

 

Method 3

  • With an sash window (lifts up/down) use a crowbar (also known as a prybar).
  • With a block of wood see if you can pry open the window using a crowbar to gently lever under the lip of the window.
  • The purpose of the block of wood is to prevent damage to the window frame.

 

Stuck Window Preventative Maintenance

Option 1 – Build up dirt in the window track

Often a stuck window is due to a build up of dirt in the tracks over the years.  This is a simple fix.

  • Open the window as far as it will go.
  • Take a tooth-brush or similar hard bristle brush, household cleaner and clean any dirt and grime in the window channels. Allow to dry.
  • Spray the window channel with a silicone lubricant spray. Let the spray dry.
  • Check to see if the window now opens and closes freely.

To maintain the window opening and closing easily clean the window tracks once or twice a year.
