Frequently Asked Questions

How much does it cost to replace all the windows in a house?

A typical 10-window whole-house project in vinyl runs about $5,500 installed, with a national range of $3,250 to $8,500. Fiberglass or wood frames, triple-pane glass, or full-frame installation push the same job to $8,000 to $12,000 or more. Most installers discount 5% to 15% for whole-house volume.

What adds the most to window replacement cost?

Frame material first: fiberglass runs about 40% more than vinyl and wood about 70% more. Then glass: triple-pane adds roughly 22% over double-pane low-E. Full-frame installation (about $175 more per window), second-story access ($75 per window), and custom or oversize units (40% to 60% more) stack on top.

Are expensive windows worth the money?

Sometimes. The energy savings from upgrading single-pane to double-pane low-E run $100 to $300 a year, so pure payback can exceed 20 years. Pay up for better glass in harsh climates, for wood where appearance demands it, and for quality hardware and installers; cheap windows installed badly fail young.
