Energy-Efficient Windows to Match Your Mercer Island Home Design

At Lake Washington Windows and Doors, we provide a variety of window replacement styles to complement every architectural design in standard and custom sizes. Our most popular window styles include:

Picture Windows: Ideal for Mercer Island homeowners seeking unobstructed views and abundant natural light, featuring large, fixed glass panes that do not open.

Casement Windows: Perfect for difficult-to-reach areas, they provide excellent ventilation when opened and form an energy-efficient seal when closed.

Bay Windows: Consisting of three or more windows extending beyond the exterior wall to create inviting nooks and showcase expansive, panoramic views.

Single-Hung Windows: A timeless choice with a traditional aesthetic, featuring two sashes—one fixed and one movable.

Double-Hung Windows: Similar to single-hung windows but with two operable sashes, designed for versatility and effective airflow.

Awning Windows: Hinging at the top and opening outward to protect your interior during light Mercer Island rains while allowing ventilation.

Horizontal Sliding Windows: Similar to sliding patio doors that move along a horizontal track, these windows are often used in living spaces and basements for their versatility.
