The short version

One replacement window runs $300 to $1,650[1] to buy and put in. A whole window project averages $7,348[1][1].

Vinyl and fiberglass windows can last 20 to 40 years[2][2]. So not every old window needs to go.

Every number on these pages links to its source. We show our math, so you can check it.

Know your window

Windows open in different ways. The way yours opens changes the price.

The frame matters too. Vinyl is about $550[1] a window. Wood is about $1,250[1].

Signs a window is wearing out

Double-pane glass tends to last 8 to 20 years[2][2]. A fogged pane often means the seal has failed.

Storm areas and old paint

In South Florida, windows face tough storm rules. Miami-Dade keeps a list of products cleared for its hurricane zone[5]. Ask your installer which rules apply to your home.

Plan your window job

You do not have to replace every window at once. You can start with the worst ones.

  1. Walk around and mark each window as good, so-so or bad.
  2. Price the bad ones first.
  3. Ask if doing more at once lowers the price per window.

For a big job, it helps to know the totals. HomeAdvisor lists 8 to 12 windows at $6,000 to $9,000[1]. The Cost vs Value report priced a 10-window vinyl job at about $22,073[3][3].

Glass choices

Pick glass for your weather. Ask the installer what makes sense where you live.

Bachi thinkingQuestions people ask

What does labor cost per window?

HomeAdvisor lists labor at $100[1] to $400[1] per window. Most of the bill is the window itself.

Is a bay window much more?

Yes. HomeAdvisor puts a bay window at about $2,500[1] each. A single-hung window is about $400[1].

Do new windows pay back when I sell?

Partly. The 2025 Cost vs Value report says vinyl window jobs got back about 76%[3] of their cost at resale.

My home is old. Is there anything special to know?

Yes. If it was built before 1978[4], the EPA has lead-safe rules for work that disturbs old paint. Hire a firm that follows them.
