Window installation — Washington, DC

Last updated: September 24, 2026

What affects the price

When you budget for new windows, several factors change the final number. The material you choose—like vinyl, wood, or fiberglass—is usually the biggest driver. You will also see price shifts based on the style of window, such as double-hung versus large picture windows, and the specific energy-efficiency ratings you select. The size of the opening and the complexity of the installation, especially if the existing frames need repair, will also adjust the total. We determine the exact pricing confirmed free on the call.
