I'm back. YUK! I just took about a little over an hour digging out dead bugs that are wedged under the inside wood window frame. I'm wondering....maybe I could use canned air to blow them out? Pressurized air from the outside? I'm almost tempted to call Andersen and find out if this is normal. We hired a very expensive builder around here in l996 and he really screwed us over in so many ways. I guess because it was a "small job" (master bedroom, bath, bedroom, hall closet and 2 walk-in closets) he hired Larry, Daryl and Daryl. It wouldn't surprise me if they put the windows in wrong. Anyhow.....Is the canned/pressurized air a good idea? I'd put the screen in for that,,,or even hold up a correct-sized piece of plywood while DH blew the air. And that's just 13 of these windows. Maybe people live with all these dead bugs packed into their window frame, but I can't.

I'm bringing this older thread up again because I'm still wondering if these casement windows were put in poorly. I'm finding bugs inside the bases of the parts of the window frames on the house side, even when they've been closed since I cleaned them all last year. Is this normal for casement windows? We paid top dollar for this builder in 1996 to put in a large addition, and he did crap work. Just thinking it's entirely possible they screwed up the window installations too. Any ideas? Thanks.

Did you try compressed air to blow the dead ones out of the frame?

We can't say that the windows were correctly or incorrectly installed without significantly more detail, however the presence of bugs has just about zero to with that. I'd recommend a seasonal cleaning with a shop vac, and yes, compressed air could also be used in stubborn areas as needed.

Unless you are having some other issues with the function or performance of the windows, it likely that there's nothing to worry about in terms of the install.

Id check for missing weather stripping.
