Thread: 30yr old Wooden Sliding Window Stuck closed

Take a pry bar to the outside of the window.

Is the outside of the sash painted?

If so, the paint gets in between the the window frame and sash. When it dries, it's like superglue. You need to scribe it with an exacto knife or something and then work into the sash/frame oopening until it is freed.

If it's not painted, I'd say you are dealing with the swelling wood issue, as mentioned above.

Not like a little stuck where it moves in the tracks, but all my might (im a pretty big guy) cannot open this window. I have sort of hit the corners with my fist, i've tried to push the window up and move it, and it wont budge.

Most of what I found online seems to not be for wooden windows. Most refer to wheels or something coming loose. Around here, every window is wood.

I dont think there is any metal in this window. It is original to the house and the house is like 30 years old. I dont think wd40 would help because it is all wood. If it would help, then I can try it, but something about oil and wood doesnt seem right...

and I have heard of using some wood to hammer the window but usually that applies to when a window is stuck open. This is stuck shut... I am not really sure how to "unstuck" it without damaging it. Just by eyeballing the frame, it looks level. Meaning, it is not tilted or anything.

Anyone have a suggestion?

If it 18C outside why the hell you want to open the window, that'll let the cold in.



Oh and only an american/canadian could infer that a 30 year old house is old. We would consider that a new homw over here.

Now that sounds painful.

18C cold?

Jeebus man! That's tanning weather in Canada!

You must be in the UK or jamaica if you think that's cold..............

Try rubbing a candle inside the tracks. It won't help initially opening it, but the more open it gets, the easier it will slide. Once fully open, rub candle in lower section of track. Open and close a few times to get even coating of wax.

If you can't get it to move at all, take a block of wood that will fit in sash channel and lightly smack it with a hammer a couple of times on each side.

Edit: I have heard baby powder will work instead of candle wax, but I have never tried it.

You can either wait, or start prying off the trim around the frame (the part that prevents the moving panel from falling into the room!) From there, get a craft knife and gently slice down the gap between the frame and the window to get it moving. Once it's out, spray with silicone spray, make sure the weights on both sides of the window are still tied, and then like the Haynes manual says, refit is the reverse of removal

Well I dont feel like removing trim pieces yet! I guess Ill have to wait... Will a blowdryer or something spped up the process?

Nope. I had read about that too. It is original paint. So actually it is painted, but not recently.

I live in the cold! I want it cold inside! Over the summer I put tin foil over the window to keep the sun out! We are supposed to get our first snow tomorrow.

You probably live in a house older than either country over here is!
