Why are there vertical ice lines inside brand new window screens?

by Kristin

New windows installed this fall. In several rooms ice forms inside screen in vertical lines. Is this normal?

    Are their drainage holes on the screens - in the frame above where these lines are forming? Just a guess...

    Any chance you can post a picture of the outside of the window? I'm wondering if it was flashed correctly. To Frugal's point, could the screens be in upside down? Is the ice just on the inside or on the outside too?

    The screens do not appear to be in upside down- but will check. They are as the installers put them in. I think the ice is also on the outside- will try taking another picture tomorrow

    Looks like the ice trails are on the outside. it could be the flashing wasn't installed right or not at all. Could also be drainage holes in the screen framing.

    Check outside to see if there is a drip from a gutter hole or soffit down onto the screen thats freezing.

    Not really normal on screen. What is above that is dripping on them and freezing. Is ice melting off of the gutter and freezing on the screen. Is gutter perhaps clogged above the window and when the icicles melt they drip?

    It is probably the gutters, not the screens. Check to see if the gutters are clean.

    I would check gutters above they must have something there

    Hello. This is a curious situation. I agree with Betsy call the installers and talk with him and see if they have an idea of what could be causing a problem I hope it is something that’s easily remedied.

    Hello, may just be the weather, and where the drainage from the roof and eaves comes down, if they are not torn, there should not be any issues and it may just be the type of screen. But check with the manufacturer to be sure.
