Double hung window installation cost — Renton, WA

Last updated: September 24, 2026

What affects the price

Replacing windows is a custom job, so your final bill depends on a few specific variables. The size and style of the window frames—like double-hung versus large picture windows—play a big role. Choosing energy-efficient glass coatings or adding decorative grids can also shift the total. We also look at the condition of your existing frames and whether the installation requires structural repairs to the surrounding wall. Your exact pricing is confirmed free on the call.

About this service

Double hung windows feature two sliding sashes, allowing ventilation from the top or bottom. The price depends on the material chosen, such as vinyl, wood, or fiberglass, as well as the size of the opening and the complexity of the trim work. Installation is typically priced in the mid-range per unit, though project size and frame condition affect the final total. Exact pricing confirmed free on the call.
