About us

Guardian Glass: Window and Glass Services in Windsor

Proudly serving Windsor for over 60 years, Guardian Glass offers complete glass & mirror services for commercial, industrial, and residential customers. What began as a small family-run business, has grown exponentially over the years.

Our crew is comprised of dedicated Skilled Tradesmen who are out in the field fixing and installing glass and aluminum products every day. We install and repair glass and mirrors for almost any application, including custom shower and bath enclosures, mirrored closet doors, and so much more. We also repair storefront windows and commercial doors, and offer a full line of industrial plastics cut to size. Whether it’s major storefronts or big retailers, we have the tools and expertise to handle projects of all sizes. We also provide on-site window and glass services throughout Windsor and Essex County, including Belle River, Amherstburg and Leamington.

We believe the secret to our success has been to provide quality workmanship using the finest products and materials available. We choose our suppliers very carefully because we feel our customers deserve the best. We feel that the “bottom line” for our customers is not just price, but the quality and value that the name Guardian Glass Ltd. has come to represent over the years with a proven history of more than six decades.

We would like to thank all of our customers, past and present, for placing their trust in us and letting us solve all of their glass and mirror needs.

Glass and Mirror Cut to Size

Windsor is a town, unlike others. We are proud of our unique houses and buildings. As much as we love them, it’s not easy to replace our broken windows or mirrors when they are in non-standard sizes.

Off-the-shelf replacements from the big box stores simply won’t “cut it.” That’s why Guardian Glass still cuts mirror and glass to your exact dimensions. And don’t worry — we won’t sell you an entire sheet of plastic or mirror when all you need is a 20” × 24” pane!

  • Glass in varied thicknesses and strengths
  • Mirrors, picture-framing glass and tabletops
  • Lexan, Plexiglas and industrial plastics
  • Quality materials from carefully chosen suppliers
