How much to install replacement windows — Denver, CO

Last updated: September 24, 2026

What affects the price

Replacing windows is a custom project, so the final total depends on a few specific variables. The size and style of the frames you choose—like double-hung versus casement—will change the materials cost. We also look at the glass packages, such as double or triple-pane options, and any energy-efficient coatings that help with insulation. The number of windows being replaced and the current condition of your home’s exterior framing play a role in the labor needed. Exact pricing confirmed free on the call.

About this service

Installation costs cover the removal of old units, the disposal of materials, and the precision fitting of new windows to prevent drafts. Prices go up if you require structural repairs around the frame or choose heavy-duty materials that demand more labor to install safely. Most homeowners plan for a budget where installation typically accounts for a significant portion of the total project cost. Exact pricing confirmed free on the call.
