Frequently Asked Questions
How much does it cost to replace windows?
Window replacement typically costs $300–$900 per window installed. Bay or bow windows run $1,000–$3,500. A 10-window house replacement averages $3,500–$9,000 depending on style, frame, glass, and region.
What's the most affordable frame material?
Vinyl offers the best value — low cost, decent energy efficiency, and minimal maintenance. Wood costs 50–60% more but is preferred for historic homes or premium aesthetics.
Is triple-pane glass worth the upgrade?
In cold climates (Zone 5+), triple-pane typically pays back in 7–12 years through reduced heating bills. In mild climates, the extra cost rarely pencils out vs. quality double-pane Low-E.
Do new windows qualify for a tax credit?
Yes — the federal 25C credit covers 30% of ENERGY STAR-certified window costs, up to $600/year through 2032.
How long does window replacement take?
A professional crew can replace 10–15 standard windows in a single day. Bay windows or full-frame replacements (removing down to the rough opening) add 2–4 hours each.
Should I replace all windows at once or in phases?
Replacing all at once typically saves 10–15% on total cost (single mobilization, bulk pricing) and ensures uniform appearance. Phasing makes sense if budget is tight — prioritize the worst-performing or north-facing windows first.
