How to Install Window Cranks

The windows in your home get a lot of use, so chances are that they might need a bit of maintenance from time to time. This could include replacing the window screen or new hardware, such as replacement window cranks. If your crank windows are sticking, a simple fix such as a new crank could solve the issue.

Crank-style windows, such as awning or casement windows, are an ideal source of fresh air and sunlight, making them highly energy efficient. However, like everything else in your home, they get a lot of wear and tear and can experience some issues.

If the issue is not something that you can fix yourself, you might need to consider windows replacement. However, in many cases, a replacement part can remedy the issue. The following blog will give you a brief guide on how to replace window cranks.

Awning & Casement Window Fixes

How to Replace Window Crank

The most common fix is to replace the window crank itself. Following is an instructional guide for replacement window cranks.

Required tools:

  • Flathead screwdriver
  • Hammer
  • Phillips-head screwdriver
  • Replacement window crank mechanism
  • Pry bar
  • Utility Knife


  • Open the window so you can easily remove the arm of the window track
  • Remove the crank cover and handle using a flathead screwdriver
  • Using a pry bar, remove the trim from the bottom of the window
  • Per the directions on the packaging, install the new crank handle
  • Replace the window trim

How to Fix a Window That is Sticking

Following are the steps to fix a window that is sticking when opened or closed.

  • Unscrew the hinge.
  • Remove the window that has been giving you the issue.
  • Shave off one to three millimeters of the edge of the window that is giving your problems. Take care not to shave off too much so as not to leave a gap, which could cause air leakage.
  • Ensure the hinges are secure and tight, and replace the window and hinge.

How to Fix a Broken Handle

Often, when the crank handle needs to be replaced, it will either fail to engage with the lock or not spin when cranked. This is often due to a stripped gear and is easily resolved by installing a new crank, which you need to order.

  • Carefully disconnect the handle of the crank from the guide track and remove the screw.
  • Slowly crank the window open until the guide is flush with the notch on the track.
  • Remove the casement cover by unscrewing the trim mounting screws inside the track.
  • Use a putty knife to pry off the casement cover and window jamb gently. Install the new crank as instructed on the packaging of the new handle.

Still, having issues after trying all the above? It may be time to contact your windows company to see if you, in fact, need to replace your crank windows.
