Let the Light In, Keep the Weather Out
Windows shape how your home looks, how bright it feels and how comfortable it stays. Drafty, foggy or hard-to-open windows make a home feel older than it is, and they let Idaho’s summer heat and winter cold right in.
Whether you’re replacing old windows or adding new ones, we install them carefully and seal them properly, so they look great and perform for years.

It’s All in the Installation
Even the best window will leak and lose energy if it isn’t installed right. Most window problems come from what happens around the frame, not the window itself.
We set every window plumb, level and square, then flash and seal it into the home’s weather-resistant barrier, so rain and wind stay outside where they belong.

Frequently Asked Questions
How much does window installation cost?
It depends on how many windows you’re replacing, their size and style, and the condition of the openings. After a quick visit to measure, we’ll give you a clear, itemized estimate.
How long does it take to install new windows?
Most of the time goes into ordering, since windows are often made to size. Once they arrive, installation moves quickly, and we’ll give you a clear schedule up front.
Can windows be replaced in the winter?
Yes. We replace one opening at a time and close it up quickly, so your home stays warm and protected while we work.
Will new windows lower my energy bills?
Well-insulated windows that are installed and sealed properly can reduce drafts and help your home hold its temperature, which can lower heating and cooling costs.
Can you add a window where there isn’t one now?
Often, yes. Adding or enlarging a window means cutting into the wall and framing a new opening. We’ll look at the structure and let you know what’s possible and whether a permit is needed.
