About Us

Window Master Inc., established in 1994, is a full-service window restoration and renovation company. We are dedicated to saving old wood windows and upgrading their energy efficiency and ease of operation.

Our services provide an alternative to new throwaway windows that don’t retain the architectural integrity of older homes. We save wood windows by reusing the old sash, upgrading single-pane glass to double-pane insulated units, and weather-stripping and draft proofing to meet modern standards. It’s a cost-effective option with historic value and eco-friendly benefits.

We started Window Master to meet the needs of architects, contractors, and homeowners, who wanted services that offer alternatives to window replacement. A key component of our work is the use of a patented Bi-Glass System® router guide tool. The Bi-Glass System allows for the cost-effective installation of insulated glass in old windows.

Our services vary from true restoration (saving the old wavy glass) and draft proofing (keeping historical sash while decreasing energy loss), to jambliner installation (for those interested in modern tilt-in features) and custom windows that match existing profiles.

Today, our business has grown to three road crews, plus a complete workshop and manufacturing facility. We are the biggest Bi-Glass licensee in the United States.

But that’s only a small part of it; learn more about what we do.
