Cost of bay window installation — Denver, CO

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.

About this service

Adding a bay window requires structural support, exterior roofing, and interior carpentry. The final price depends on the materials chosen, the complexity of the framing, and how much modification your wall needs to accommodate the new shape. Because this is a significant renovation, it represents a higher investment than a standard window swap. Exact pricing confirmed free on the call.
