About Us

K Windows is a family-run window and door installation company serving homeowners and property managers across Lake County and the western suburbs of Chicago.

We specialize in thoughtful recommendations, dependable scheduling, and clean, detail-focused installations built to last. Every project is approached with the same standard: do it right, communicate clearly, and leave the space better than we found it.

Our work spans full window and door replacements, entry systems, and custom solutions for residential, multi-unit, and commercial properties. Whether we are coordinating with a homeowner, association board, property manager, or real estate investor, we prioritize clarity, professionalism, and craftsmanship at every step.

As a family business, our reputation matters. We stand behind our work, show up when we say we will, and treat each property with respect.

If you're looking for straightforward guidance and quality installation without the sales pressure, we're here to help.
