Windows in Duvall, WA
Windows for Duvall homes, from Builders Service Company.

Windows in Duvall usually date from one of two eras. Homes built between 1980 and 1999 often have first-generation vinyl windows, and many of those now have failing seals. Homes built in 2000 or later usually have builder-grade windows that are reaching replacement age.
We install Preservation 9000 vinyl replacement windows, and we are the exclusive provider of Preservation 9000 windows in Washington. Styles include double-hung, slider, casement and awning, hopper, picture, garden, bay and bow, and custom shapes. We match the style to the room:
- Upper floors and tight eaves on two-story homes: sliders or casements.
- View rooms: picture windows and bay or bow units. King County assessor records show 7% of homes here have a view.
- Kitchens and baths that need ventilation: casement, awning or hopper.
Census data shows 35% of homes heat with electricity, and where heating is costly, the payback from efficient windows is larger. Electric service comes from PSE, so check with PSE for current programs before you order.
With 86% of homes owner-occupied, most owners here are long-term owners investing in their exteriors, and installation quality matters as much as the window. Our installers make sure each window is right-sized, properly aligned and tightly sealed so it performs as intended.

Duvall windows FAQ
Why do windows in 1980s and 1990s Duvall homes fog up?
Fogging between panes usually means a failed seal. Homes built between 1980 and 1999 often have first-generation vinyl windows, and many of those seals are now giving out. We replace them with Preservation 9000 vinyl replacement windows, and we are the exclusive provider of Preservation 9000 windows in Washington. Each window is right-sized, properly aligned and tightly sealed during installation.
