Products Developed From Real Restoration Work

Chosen Wood Window Maintenance has been restoring historic wood windows for over 25 years, with offices in Oregon and Washington. We've completed projects throughout the Pacific Northwest and beyond on a wide range of historic buildings.

Our work includes some of the most recognised landmarks in the country — Timberline Lodge, Crater Lake Lodge, and Fort Yellowstone, the National Historic Landmark where the policies that shaped the modern National Park Service were developed.

Each one was developed in response to real project challenges the need for reversibility, preservation compliance, thermal performance, and visual accuracy that architects and preservation boards actually require.
