What is the Average Cost of a Window Replacement Project?

Table of Contents

A lot of people want to know what a window replacement costs, and the reality is that it really depends on various factors. The average American changes around eight windows at a time, so if you’re replacing eight windows, it’s much more affordable than if you’re looking to replace 30 to 40 windows. In this blog post, we will explore the average cost of a window replacement project and explore the key factors that influence pricing.

Window Types and Costs

When it comes to window replacement, the type of window you choose plays a significant role in determining the overall cost. Here are some common window types and their average costs:

  1. Vinyl Windows: If you’re considering replacing three or four vinyl windows, you can expect to pay somewhere between $800 to $1,000 per window. Vinyl windows are often a budget-friendly option.
  2. Fiberglass Windows: Opting for fiberglass windows will typically cost you around $1,500 to $1,800 per window. Many homeowners prefer fiberglass due to its durability and energy efficiency.
  3. Wood Interior: If you desire the warmth and character of a wood interior, be prepared to invest over $2,000 per window. While it may be more expensive, wood interiors add a unique touch to your home.

It’s important to note that window prices can vary significantly, ranging from $300 to $4,000 or more, depending on the brand, features, and customization options. However, for most homeowners, fiberglass windows priced at $1,500 to $1,800 are a popular choice for their quality and energy efficiency.

Installation Methods and Cost Savings

Another crucial factor that affects the cost of window replacement is the installation method. There are two main approaches: window replacement and full tear.

  1. Window Replacement: This method involves removing the old window and installing a new one within the existing frame. It does not require replacing the interior or exterior trim. Choosing this option can save you $300 to $400 per window.
  2. Full Tear: In a full tear installation, both the interior and exterior trim are replaced, resulting in a more comprehensive upgrade. However, this approach adds 3 to 4 hours of labor per window, which can increase the overall cost.

Consider Your Budget and Priorities

A crucial decision to make is whether to prioritize window replacement or other home improvement projects like siding. The order in which you tackle these projects can impact your budget and convenience.

For most homeowners, replacing windows first makes sense. Since the average homeowner replaces around eight windows at a time, addressing the ones that need immediate attention can improve your home’s comfort and energy efficiency. Down the road, you can replace the remaining windows when your budget allows.

If you decide to install new siding after replacing windows, you’ll avoid the need to reach some of those windows twice. However, it’s important to budget for both projects separately, as adding window replacement to a full siding project can cost a couple of thousand dollars extra.


The average cost of a window replacement project varies based on window type, installation method, and your specific preferences. While vinyl windows offer affordability, fiberglass windows are favored for their durability and energy efficiency. Choosing between window replacement and full tear installation can also impact your budget.

Before embarking on a window replacement project, it’s essential to consider your priorities and budget carefully. Whether you opt to replace a few windows or your entire house, understanding the factors that influence costs will help you make an informed decision.
