Frequently Asked Questions
What window styles do you install?
Double-hung, casement, sliding, bay & bow, and triple-pane windows, with awning and garden options available. Every window is custom-built to your opening and matched to your home and our climate.
Are your windows energy efficient?
Yes. We install ENERGY STAR®-certified windows for the Northern climate zone, with Low-E glass and argon-gas fills, plus triple-pane options for the coldest exposures — cutting drafts and lowering energy bills through North Dakota winters.

Most full-home projects take one to three days of on-site installation. Custom windows typically have a 6–10 week manufacturing lead time; we schedule the install once your windows are ready.
