How to open a closed window

Have you ever tried to open a stuck casement window a bunch of times yet unfortunately, you were unsuccessful? Maybe, you even got angry and thought about throwing a rock through it!

Well, I am here to tell you that there are actually quite a few reasons why this casement window is actually stuck so before you try shattering it, why don’t we go ahead and try to identify the problem so that we can come up with a less messy and dangerous way fix the problem, shall we?

First and foremost, we have to make sure we have the right equipment. First, I need to start by giving you a little bit of advice before we start. It is much better to do this when the weather is cool and not so hot. Unfortunately, the humidity can cause swelling in the trim of the window making it more difficult to open.


  • Serrated Blade
  • Hammer
  • Block of Wood
  • Towel
  • Putty Knives
  • Lubricant
  • Sandpaper
  • Varnish

How to open a closed window

Step 1:

First, we are going to use our serrated blade. With this, we want to start by tapping or sawing through any of the dry paint. We want to do this from the gap between the sash and frame. To get into the space we can use the hammer to tap the blades handle. Also, we will do this to the exterior side as well.

Step 2:

Next, we will take the block of wood and wrap our towel around it so that we can hold it against the sash.In order to help get any extra dry paint or remaining debris, we can take our hammer and tap the covered block. This can be continued around all the windows edges.

Step 3:

Along the window stop, we will be repeating the “block and hammer” process so therefore it will bind against the sash and this will prevent it all from moving too much.

Step 4:

Moving over to the opposite side of the hinges, we are going to take the head of our putty knife and place it in the lower section, where you will see the crevice in which will be between the sash and the frame. To pry it open you will GENTLY bend the handle of your putty knife. We will continue to do this same thing all the way up to the top and also along the top and bottom edges because we want to break the seal of all the sticky residue in all these spaces so that you will be able to move stiff hinges more easily. If you need additional leverage, you can use two putty knives.

Step 5:

Next, we will take our lubricant in which can be Lithium grease or even a spray lubricant such as WD-40, and spray the hinges. Make sure to tighten up any loose screws that you might see. If the hinges are heavily rusted, it is suggested that we go ahead and remove them so that we can replace them.

Step 6:

No we are going to lubricate the inner gears but first we have to remove the crank’s cover. Doing so will prevent sticking as they turn.

Step 7:

If there is excess paint, we will sand the sections where the sash and frame meet. When finished with that we will apply a varnish to seal it. To further prevent sticking, rub those sections with wax candle.
