Andersen Windows
Andersen windows offer wood, composite, and clad options across different product lines, giving you choices that can complement your home's architectural character. A window inspection helps us evaluate existing openings, operation, and trim conditions before discussing suitable configurations. Our Andersen window installation and window replacement planning considers the look you want to preserve, the fit of each opening, and the flashing details needed where new windows meet the exterior.

Andersen Wood and Composite Windows for Seattle Homes
Understand Andersen’s different material strategies
“Andersen window” does not describe one frame construction. Andersen explains that wood is used for structure, interior appearance, and thermal qualities in several lines, often protected outside by cladding. Its 100 Series instead uses Fibrex, a proprietary composite made from wood fiber and thermoplastic polymer. Those systems produce different profiles, finish choices, and maintenance considerations.
Begin with the room-facing goal: a stainable wood interior, a painted appearance, or a lower-maintenance composite surface. Then compare exterior exposure and sightlines. Do not assume that every color, species, hardware set, or operating type is offered in every Andersen series.
Match the series to the house
A traditional home may benefit from wood interiors, divided-light patterns, and trim proportions that respect existing openings. A contemporary remodel may favor the narrower profiles and dark finishes Andersen describes for 100 Series Fibrex products. The right decision comes from comparing actual cross-sections and samples—not simply selecting the most familiar brand tier.
Inventory what makes the existing façade coherent: sash proportions, sill projection, casing width, grille pattern, and alignment across grouped windows. Replacing one elevation without that study can create mismatched glass lines. Inside, consider stools, jamb extensions, shades, and whether new frame depth changes the finish carpentry.
