How Much Does it Cost to Replace Windows?

*Updated November 25th, 2025

Your home’s integrity relies heavily on the quality of its windows. Window replacement often occurs out of necessity—such as broken or leaking windows—but sometimes the goal is cosmetic improvement. Because windows offer insulation, protection from the elements, and aesthetic appeal, they are an important home improvement purchase. But how much does it actually cost to replace windows?

Average Cost to Replace Windows

With many window options available, the average cost to replace windows varies widely. On average, one replacement window costs about $850 per window, according to Angi, though window replacement cost varies based on the type of window, the window frame material, the size, and the number of windows.

Some common window styles include:

• Double-hung windows – The window slides from top to bottom

• Single-hung windows – Only one pane moves from bottom to top

• Sliding windows – Slide open horizontally

• Stationary or picture windows – Do not open

If you need to replace the window frame, it adds to the cost to replace. Among available options, a vinyl window is often the most affordable and durable choice for window replacement projects. Other popular window materials include:

• Vinyl

• Wood windows

• Fiberglass windows

• Aluminum

• Composite windows

Additional features—such as energy-efficient windows, double- or triple-pane glass, or coatings—can increase overall replacement window costs, but they often provide long-term savings and better performance.

How to Save on Window Replacement Costs

Many homeowners try DIY home improvement projects to save money, but window installation is not something you should attempt yourself. Improper installation can create leaks, drafts, poor energy efficiency, or structural issues. Between the cost of tools, the time involved, and the risks, a professional can install replacement windows far faster and with better long-term results.

Instead of DIY window replacement, consider these ways to save:

• Replace all your windows at once. Bulk pricing is often lower than replacing a single window.

• Shop around. Contact at least three window companies to compare pricing and options.

• Ask about materials. Compare vinyl, wood, fiberglass, aluminum, and composite to balance cost and performance.

• Compare window styles. Window type affects windows cost, from bay windows to fixed windows to casement windows.

Buying multiple windows from one window company and hiring one window installer typically lowers the cost per window and simplifies the entire process.

Choosing a Window Replacement Company

When choosing a window replacement company, prioritize those with strong reputations and proven experience in window installation. Customer reviews and testimonials help you understand the reliability and quality of service. Also look for certifications, workmanship guarantees, and product warranties.

When consulting with companies, ask about:

• Their experience with your window style

• Detailed quotes including labor

• Differences in replacement window materials

• Expected timeline for installing multiple windows

• Brands they offer (since window brands vary greatly in cost and quality)

A reliable company should be transparent about the window replacement cost, the installation process, and any additional work needed—such as repairing an old window, widening a window opening, or addressing rotting frames.

Taking time to select the right company ensures your window replacement project runs smoothly and your new windows stand the test of time.
