If you’re a homeowner and thinking about getting new windows, you’re probably wondering:
How much does window installation really cost?

That’s a smart question. Many people are surprised when they see the price. It’s not just about the cost of the window itself — labor, materials, window type, and installation style all affect the final price.

In this guide, we’ll break down the true cost of a home window installation. We’ll use simple terms, real numbers, and helpful examples so you can plan your project with confidence.

Why New Windows Matter

Before we talk dollars, let’s talk about why new windows are a good idea. Replacing old windows can:

• Lower energy bills by up to 12% (according to Energy.gov)
• Keep your home quieter and more comfortable
• Add value to your home (windows give up to 72% return on investment per Remodeling Magazine’s 2023 report)
• Improve curb appeal

But how much does all that cost? Let’s dive in.

What Affects the Cost of Window Installation?

There are a few big things that affect how much you’ll pay:

Cost Factor	What It Means
Type of Window	Vinyl, wood, aluminum, or fiberglass—all have different price points
Installation Method	Retrofit (easier) or full tear-out (more work)
Labor	Number of windows, time on site, and size of the crew
Size and Shape	Bigger or custom-shaped windows cost more
Location of Home	Prices vary by region (Milwaukee is lower than national averages in many cases)

1. Retrofit Window Installation (Insert Replacement)

What It Is:

This method keeps your existing frame and trims. Only the glass and inner frame get replaced. It’s fast and less messy.

Average Cost per Window:

• Window: $400 to $600
• Labor: $300 to $500
• Total: $700 to $1,100 per window

Example:

If you do one window, you might pay:

• Window: $420
• Labor: $800 (higher due to single service call)
• Total: $1,220

But if you do 10 windows:

• Windows: $4,500
• Labor: $3,000
• Total: $7,500
• Per window: $750

Tip: The more windows you replace at once, the cheaper the cost per window becomes.

2. Full Tear-Out Window Installation

What It Is:

This means removing the entire window—glass, frame, trim, everything—and installing a brand-new unit.

When to Choose It:

• If your current frames are rotting or damaged
• If you’re switching to a different style or material
• For wood or older aluminum windows

Average Cost per Window:

• Window: $600 to $900
• Labor: $700 to $900
• Total: $1,300 to $1,800

Why It Costs More:

It takes longer, involves more tools and materials, and may require outside trim work or drywall repair.

Example:

For a full tear-out of 5 windows:

• Windows: $4,000
• Labor: $4,000
• Total: $8,000
• Per window: $1,600

3. New Construction Window Installation

What It Is:

This is done during new builds or major remodels where walls are open. Windows are nailed right into the framing.

Average Cost per Window:

• Window: $300 to $700
• Labor: $150 to $350
• Total: $450 to $1,050

When It’s Used:

• Home additions
• New home builds
• Full wall renovations

Advantage:

Fast, simple, and lower labor costs.

4. Wood vs. Vinyl Windows: Which Is Cheaper?

Window Material	Pros	Cons	Average Price (Window Only)
Vinyl	Affordable, energy efficient, low maintenance	Limited color options	$300–$600
Wood	Classic look, can be painted	Expensive, high maintenance	$800–$1,200
Fiberglass	Durable, good insulation	Costly	$600–$900
Aluminum	Strong, thin frame	Poor insulation, can corrode	$400–$700

Hidden Costs You Might Not Expect

Besides windows and labor, here are some other costs that could come up:

• Permit Fees: $50–$200 depending on your city
• Disposal Fees: Some companies charge to remove old windows
• Drywall or Siding Repair: Especially for full tear-outs
• Trim or Paint Touch-Ups: Interior or exterior
• Upgrades: Triple-pane glass, custom finishes, special locks

Tip: Always ask for an itemized quote before you sign.

How Many Windows Should You Replace at Once?

You might think replacing one or two windows is cheaper. But doing multiple windows in one project can actually save you money.

Here’s Why:

• Labor is shared across more windows
• Fewer trips = less cost per visit
• Better volume pricing on windows

Cost Comparison:

Number of Windows	Total Cost	Cost Per Window
1 Window	$1,200	$1,200
5 Windows	$5,500	$1,100
10 Windows	$7,800	$780

As you can see, cost per window drops the more you do.

Are New Windows Worth the Money?

According to Remodeling Magazine’s 2023 Cost vs. Value Report:

• Replacing old windows with energy-efficient ones gives back up to 72% of the cost in added home value.
• You could also save $100–$500 a year on energy bills depending on where you live (Energy Star).

What’s the Cheapest Option?

If you’re on a tight budget:

• Choose vinyl windows
• Go with retrofit installation
• Replace multiple windows at once
• Skip fancy upgrades like grids or special coatings

That said, don’t skimp on installation. A poor install can cause:

• Air leaks
• Water damage
• Higher energy bills
• Mold or mildew around windows

What Do Most Homeowners Pay?

Here’s a quick national and local breakdown:

Project Type	National Average	Milwaukee Average
1 Vinyl Window (Retrofit)	$700–$1,100	$650–$1,000
1 Wood Window (Full Tear-Out)	$1,300–$1,800	$1,200–$1,600
10 Vinyl Windows	$7,500–$9,500	$7,000–$8,500
