Window replacement cost

Drafty, foggy or stuck windows? Here is what new ones tend to cost, in plain words.

Quick answer

$300 to $1,650^[1] per replacement window.

That is to buy and put in one window. A whole window project averages $7,348^[1]. The frame, the glass and how many windows you need change the price most.

Old windows can let in drafts, rain and noise. New ones can make a room feel better right away.

But windows are priced one at a time, so the bill adds up fast. This guide shows how.

Each number links to its source. We show our math, so you can check it.

What each frame costs

The frame is the part that holds the glass. It is the biggest choice you make^[1].

Vinyl is low in price and needs little care. Wood looks warm but needs paint. Fiberglass is strong and costs more.

What it costs by number of windows

The Cost vs Value report prices a nicer job: 10^[3] vinyl windows^[3]. It averaged $22,073^[2] in 2025. The same job in wood averaged $26,781^[2][2]. So quotes can run well above the table.

Glass and window styles

One pane of glass is cheapest: $150 to $450^[1]. Two panes cost $450 to $1,000^[1]. Three panes cost $500 to $2,000^[1]. More panes keep heat and noise out better^[1].

• Single-hung: about $400^[1]. Only the bottom part slides up.
• Double-hung: about $700^[1]. Both parts slide.
• Casement: about $900^[1]. It swings out with a crank.
• Sliding: about $1,000^[1]. It slides side to side.
• Egress: about $2,300^[1]. A big window you can climb out of in a fire.
• Bay: about $2,500^[1]. It pokes out from the wall.

What labor costs

Labor is only about 15%^[1] of a window job. Most of the bill is the window. Labor runs $100 to $400^[1] per window^[1].

A window in a brand-new opening is a much bigger job. It can cost up to about $5,000^[1].

What carpenters earn in every state

The government has no pay data just for window installers. Carpenters are the closest group. The U.S. middle was $29.12/hr^[4] in May 2025^[4].

Example: ten vinyl windows in Florida

Say you live in Florida. You want to swap 10 old windows for vinyl ones. Here is the math.

Our total comes in below HomeAdvisor's range for eight to twelve windows. Averages from two tables do not always line up. Plan for the higher number. In much of South Florida, windows must also meet hurricane rules. Miami-Dade keeps a list of approved products^[7]. Impact windows cost more.

Ways to pay less

• Get three written quotes. Ask each to list the brand, frame, glass and labor for each window.
• Keep the same sizes. A window that fits the old opening costs far less than a new opening.
• Pick the frame for your weather. Vinyl is a solid, low-cost pick for many homes.
• Do the worst windows first. You do not have to replace them all at once.
• Ask about lead rules. If your home is old, make sure the crew is certified. It avoids delays.

Fix it or replace it?

Vinyl and fiberglass windows can last 20 to 40 years^[5]. Wood can last 30+ years^[5] with care. Aluminum lasts 15 to 20 years^[5][5].

A stuck sash or a torn screen is an easy fix. Rot, fog between the panes, or drafts all over may mean new windows. See our fix or replace guide for windows.

What makes the price go up or down

• How many windows. Six to eight windows run $4,500 to $6,000^[1]. Twenty to 24 run $15,000 to $18,000^[1].
• Frame type. Aluminum is about $450^[1] a window. Fiberglass is about $1,100^[1].
• Panes of glass. Single-pane is cheapest: $150 to $450^[1].
• New opening or same hole. A window that fits the old space is far cheaper than cutting a new hole, which can reach about $5,000^[1].
• Special windows. An egress window, big enough to climb out of, is about $2,300^[1].

Permits and storm rules

Some towns ask for a permit to change windows. Rules are stricter where storms hit hard. In Miami-Dade, windows need to be on the county's product list^[7].

Homes built before 1978^[6] fall under EPA lead-safe rules for work that disturbs paint^[6]. Ask if your installer's firm follows them.

Questions to ask an installer

• Is this a replacement window, or a full new-frame job?
• What frame and glass is in the quote?
• Who handles the permit?
• What does the warranty cover, and for how long?
• Will you fix the trim inside and out?

Can you do it yourself?

Some handy people put in one or two windows. It is hard to get the seal right, and a bad seal lets water into the wall. In storm areas, the rules on how windows are fastened can be strict.

Labor is only about 15%^[1] of a window project, so doing it yourself saves less than you might think.
