How much does window replacement cost?

Vinyl replacement windows run $400–$900 installed each. Fiberglass and composite frames (Andersen Fibrex) cost $900–$1,600. Wood-clad windows reach $1,500–$2,500. A 10-window project typically lands at $7,000–$15,000.

Are new windows worth the money?

Energy-Star qualified windows save 12–33% on heating/cooling per the EPA. Cost vs. Value reports show ~70% return at resale, and most projects pay back in energy savings in 7–12 years.

What's the difference between vinyl and Fibrex?

Vinyl is the most affordable and lowest-maintenance frame. Fibrex (Andersen Renewal proprietary composite) is twice as strong as vinyl, holds paint better, and is warrantied to never warp.

Are there tax credits?

Yes - the federal Energy Efficient Home Improvement Credit covers 30% of qualifying window costs up to $600/year through 2032.

Insert vs. full-frame replacement?

Insert installs slip a new window into the existing frame and are 30–50% cheaper. Full-frame replacements remove everything down to the rough opening and are required if the frame is rotted or you want a different window size.
