About Legacy Glass Block & Window Co.
We're Not Just Another Contractor. We're Your Neighbors.
At Legacy Glass Block & Window Co., we've spent over 40 years doing one thing exceptionally well — helping Chicagoland homeowners protect, improve, and fall in love with their homes. We're a family-owned business based right here in Mokena, Illinois, and every project we take on is treated with the same care and pride we'd give our own home.
We started as glass block specialists — and we're still the best in the business at it. Over the decades, we've grown to offer replacement windows, entry and patio doors, and siding, because our customers kept asking, and we never say no to a neighbor who needs help.
