Questions window contractors actually ask

Straight answers, no fluff. Then run your own numbers above.

How much does it cost to replace a window in 2026?

Vinyl double-hung windows run $400–$800 installed each; fiberglass $700–$1,200; wood/clad $900–$1,600. Bay and bow windows start around $1,800. Full-frame replacement adds roughly 30–50% over retrofit.

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

A typical home with 10 vinyl windows costs $5,000–$9,000 installed. Whole-house jobs with premium materials run $12,000–$25,000+. The calculator above prices your exact count, type, and material.

Retrofit vs. full-frame window replacement?

Retrofit (insert) fits the new window into the existing frame — faster and cheaper. Full-frame removes everything down to the studs, fixing rot and air leaks but costing 30–50% more. Quote retrofit by default; sell full-frame where frames are damaged.

How long does it take to install a window?

About 30–60 minutes per window for retrofit, 1–2 hours for full-frame. A 10-window house is usually a one-day job for a two-person crew.
