Window Replacement in Seattle & The Eastside
Milgard is our primary window line. We also consider Marvin for premium and design-focused projects, and Weather Shield for specialty applications when they fit.
Schedule a Window ConsultationStart with the window and the opening
Window selection is only part of the decision. We review the existing frame, surrounding exterior, and interior finish so the agreed scope accounts for the work around the opening.
Whether an existing frame can remain or a full-frame replacement is appropriate depends on field conditions, product requirements, and project goals. The proposal identifies the selected windows and agreed flashing, trim, siding, drywall, and paint work.

Step 4
Your completed package is covered by our 20-year workmanship warranty.
A curated window lineup
We guide the choice around the home, design priorities, and scope rather than treating every product line as interchangeable.
Marvin
A premium and design-focused direction when it fits the project.
Weather Shield
A specialty option for applications where it fits the home and scope.
Explore manufacturer product guides
Start with manufacturer-published information, then confirm current options and the installation scope for your home.
Explore window materials
Review the existing material guides, then discuss product and installation choices for your home.
Vinyl windows
Choose standard or higher-spec vinyl windows for straightforward maintenance and broad style options. We review frame color, operation, glass, screens, and trim before preparing your proposal.
Learn moreFiberglass windows
Fiberglass frames provide a slim profile, stable material, and more finish choices than many vinyl lines. They work well where exposure and larger glass areas matter.
Learn moreWood-clad windows
Wood interiors with aluminum-clad exteriors suit homes where interior finish and exterior profile both matter. Each opening is reviewed for exposure and finish work.
