Why Integrity

A different kind of window company

Most window companies sell a product. We deliver confidence and professionalism that extends well beyond the glass — combining premium products with experience, execution, and peace of mind.

“Integrity…because it matters.”

  • Products that perform

    Premium, energy-efficient windows suitable for both residential and commercial applications — backed by a manufacturer building in Illinois since 1947.

  • Real-world property insight

    A decade-plus as licensed real estate brokers means we understand exactly how window performance impacts comfort, operating costs, and long-term property value.

  • Disciplined project management

    Every install is planned and managed with the rigor of military leadership and complex-project oversight — on schedule, on spec, accountable.

  • One seasoned crew

    Our installation team has worked together for years and works with us exclusively, delivering consistent craftsmanship on every project.

  • Integrity, start to finish

    Transparency and long-term relationships over one-off sales. Integrity is not just our name — it is the standard by which we operate.

About Us

The story behind Integrity Windows

Integrity Windows was born out of real experience and trusted relationships. For more than a decade as licensed real estate brokers, we worked with homeowners, property owners, and investors who faced the same recurring challenge: aging, inefficient windows quietly eroding comfort, energy performance, and long-term value.

The solution emerged through a long-standing relationship with the owner of Lindsay Windows in Aurora, Illinois — a family-owned manufacturer founded in 1947. As referrals grew, it became clear that clients needed more than a manufacturer. They needed trusted guidance, disciplined execution, and accountability from consultation through installation.

Leading that work is Mark Metzger — a former U.S. Navy Commanding Officer, project management consultant, and licensed real estate broker. His decades of leadership, logistics, and home-renovation experience ensure every residential and commercial installation is carefully planned and professionally managed, supported by a skilled crew that has worked together for years.

This is more than windows. It is integrity, experience, and execution — working together for every property we serve.
