How do I get my full screen back into a double hung window?

Hello Mary, Make sure you are using the same screen taken from each window. Don't mix them up. It's like making a puzzle. Over time our homes settle and just the slightest imperfection makes it impossible to fit a square peg into a round hole. Be patient and keep trying. Once you find the right fit, mark the screen for the room it is in and which end is up. So you won't have this same problem next time it's time to rescreen the windows. Good luck. Wishing you all the best.

Mary - If these were the screens from the original frame of the window they will slide into their frame support. If the screens are retro fit screens they will need brackets to hold them in place. Back to the orginanl screens. There is a channel at the top of the window for the screen framw to slide into. On top of the screen there is a small tin arch extending from the screen top. This is the top of the screen that will fit into the channel at the top of your window. On the inside of the screen there are two black tabs that should be facing you on the bottom of the screen. After inserting the screen in the channel push up and pull the screen toward you with the black tabs on the inside of the screen.

As you pull the screen toward you lift up the screen to clear the bottom channel of your window. This is where you will place the bottom of the screen. Your screen is properly install back into your window opening.

You Tube will be a good resource for help also.
