Topic tags/keywords: window crank casing screw holes filler

Hey guys,

I have a crank-style window that is broken and was wondering if you could help.

The problem was that when you turned the crank, the mechanism wobbled and the window would get stuck.

I opened the window manually, disengaged the crank arm, and unscrewed the mechanism from the bottom of the window casing. I then cleaned and lubricated everything.

The problem is that the window casing itself is made out of plastic, and the screw holes are completely stripped and/or stretched.

I tried using wall plugs but that didn’t do much.

So now, how do I screw the mechanism back into the window casing? I have to follow the hole pattern on the mechanism (use the same screw holes) and shifting it to one side is not an option.

Is there some sort of filler I can use and then re-screw into that?

Thanks guys

Is this a vinyl window? Crank window = casement or awning or hopper window?
And I am assuming the window casing reference is for the window sash or is it the the actual jamb/frame of the window?
A paste epoxy or bondo may work if it’s a vinyl window. The problem with vinyl windows is that the frames are extrusions and normally hollow. This can make it difficult to repair.

Hi Gary, thanks for the response. Sorry that I do not know the correct names of all the window parts.

Yes I guess it must be made of vinyl. And yes it is hollow once you puncture through the vinyl; there are two thin layers of it close together, then a hollow cavity underneath.

Can you recommend a good name brand of epoxy that i can try?

Thanks again

I have West Systems on hand with a fiber thickener. I know there are paste epoxies that you can knead together but I have never used them. Maybe someone else can give a suggestion that a big box store may have.
Can you drill out the hardware/mechanism to fit a bigger diameter screw? This will give some more bite into the existing stripped out hole. If this is possible use a stainless screw.

I’m thinking marine epoxy putty will do the job nicely. A brand name doesn’t come to Mind. The kind I use comes as a cylinder. It’s green on the outside and white on the inside. Just slice off about a quarter inch and knead it until it is a solid color. Stuff it in the hole. Wait 5 minutes then shave off the excess. When it cures carefully re-drill the holes and the rest is yours.

Although you can mix it with bare hands, I’d wear a pair of disposable gloves.

Best of luck!

Regardless if it is made of plastic or wood, I guess this can be replace however this need to be restored by the expert. As additional protection when it is done, you can have options to add fabric window awning or perhaps PVC type window covers, those type of window protections are available at http://coastwideshadesails.com.au/shade-sails-products/pvc-coated-polyester/ I have installed on every window in the house and for more than 2 years, still in good condition.
