Frequently asked questions

How much does window replacement cost per window?

Most U.S. homeowners pay about $650 to $1,900 per window installed, depending on size, frame material and glass. A typical whole-house project of 10 to 20 windows lands around $7,500 to $34,000.

Is it cheaper to replace all windows at once?

Usually, yes. Contractors spread setup, travel and crew time across more openings, and manufacturers often discount larger orders. Doing it in phases works, but expect a higher per-window price.

Vinyl vs. fiberglass windows: which is better?

Vinyl is the most common and lowest-cost frame. Fiberglass costs more but expands less with temperature changes, holds paint and suits dark colors and large openings. Both outlast older aluminum frames in most climates.

Do replacement windows need a permit?

Many U.S. jurisdictions require a permit when the opening size, egress or structure changes, and some require one for any replacement. In high-wind coastal areas, product approvals and design-pressure ratings are part of the review.
