Preserving Seattle's windows, one sash at a time

RAD Double-Hung Window Specialist is the work of Jeff, a craftsman who believes the original windows in Seattle's historic homes are worth saving, not tearing out.

A restoration-first philosophy

Modern replacement windows are sold on the promise of convenience, but they discard something that can't be bought back: the old-growth fir and cedar sashes that were built to be repaired and to last a century or more. Our approach is simple, restore what's there whenever it's sound, repair what's failing, and replicate only what's truly beyond saving.

That philosophy protects your home's architectural character, its resale value in Seattle's historic neighborhoods, and a piece of craftsmanship that's increasingly rare.

Personalized service, start to finish

When you hire RAD, you work directly with the same craftsman from the first consultation through the final walkthrough. There's no rotating crew and no salesperson handing you off, just one person who's personally accountable for the quality of every sash, cord, and pane.
