Mercer Island’s homes are a reflection of its charm and natural beauty, and your windows play a key role in showcasing that elegance. Single-hung windows from Synapse Construction offer a timeless design with modern functionality, making them a perfect fit for Mercer Island’s unique climate and aesthetic. Whether you’re building new or upgrading old windows, our single-hung window installation and replacement services bring durability, efficiency, and style to your home.

What Are Single-Hung Windows?

Single-hung windows are a classic choice for homeowners seeking simplicity and practicality. They feature two panels, or sashes, with the bottom sash sliding vertically while the upper sash remains fixed. This design offers a clean, traditional appearance that suits both modern and historic homes on Mercer Island.

Why Upgrade to Single-Hung Windows?

Replacing outdated windows with modern single-hung designs offers several benefits:

Energy Efficiency: Their fixed upper sash and tight seal help reduce drafts and maintain a consistent indoor temperature.
Space-Saving Design: Sliding vertically, these windows don’t take up extra room, making them ideal for tighter spaces.
Timeless Style: The simple, elegant look complements a variety of architectural styles.

If your current windows are hard to open, drafty, or no longer secure, it’s time to consider single-hung window replacement.
