Flashing keeps the water out
The window is a component. The sill pan, the side flashing and the head flashing are what stop a leak into the wall. We do those layers even on a same-size replacement.

Windows in Mercer Island, WA
Energy-efficient casement, double-hung and sliding units — flashed so the opening stays dry. For Mercer Island — Island-wide, including waterfront properties — Large island openings take rain on the glass and wind at the sash. Casements earn their place here, and the flashing schedule is not optional.

- Flashing and a sill pan, then the window, then the trim
- Interior casing repaired or replaced so the room looks finished
- Haul-off of the old units
Local notes
Style is a performance choice
Casement seals tight. Double-hung fits older elevations. Sliders belong on a wide wall. We will not put the wrong operation in a hole just because it was in stock.

Questions
Before you call
Do you work in Island-wide, including waterfront properties?
Yes. Design-sensitive streets, wind off the lake, and HOAs that read material samples closely. If you are nearby in Redmond, Issaquah or Newcastle, ask — those addresses are in the same service area.
How long does window replacement take?
Most projects run 1–3 days for a typical home, depending on the number of openings. A full-house package takes longer, and custom sizes add lead time before the first day on site.
