Retrofit vinyl window warped at top

Posted by alan_s_thefirst (My Page) on

My house was built in the mid-80's and has a number of retrofitted vinyl windows. The bathroom one has begun to bow downwards from the top - there's a wood sill incorporated and it's actually separated from the vinyl where they join.

I can't say if it's always been warped, or if it's just happened (it was never painted, and the factory undercoat is starting to come off, so it clearly needs painting.) It may have warped from the humidity, I'm not sure.

I was going to remove some trim and see if it was sprayfoamed incorrectly, in which case I'd cut some away and re-do it with the correct stuff.

What I thought I'd do is drive a few screws across the top, upwards, to pull it back square (it is opening and closing ok) gently, a few turns at a time.

I also noticed that when they installed it, they put a screw through the side of the vinyl part near the outside, rather than through the wood part, where I'd think the best part to fit a retrofit window would be.

Is this a good idea, or should I leave it? Now I'm aware of it, I hate the look of the bowed section.

How long ago were the windows installed? If they used regular expanding foam instead of low expanding foam, there's a chance they bowed the window frame. If the vinyl is bowed, it's likely the only solution is going to be to replace it.

More than five years ago, but here's the thing - the vinyl is fine, the wood part that adjoins it (it's on the inside of the house side of the vinyl) is what's bowed. There was a filler/adhesive between the vinyl and the wood, and they've separated. The fact that I can push the wood back up into place, and the vinyl stays where it should makes me think it might be fixable.
