Window Master NH - Window Replacements - Restoration of Wood Windows
  About Us

Preserving Architectural Integrity

Our services provide an alternative to new throwaway windows that donít 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. Itís a cost-effective option with historic value and eco-friendly benefits.

Offering Alternatives to Window Replacement

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 Systemģ router guide tool. The Bi-Glass System allows for the cost-effective installation of insulated glass in old windows.

Restoration - Draft Proofing - Jambliner Installation

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 thatís only a small part of it; learn more about what we do.
