Replacement window costs vary widely, from $200 for a cheap DIY project all the way up to $4,000+ for a custom, professionally-installed window. It all depends on multiple factors, like the style of window (casement, double hung, slider, etc), frame material (should you go with cheap vinyl or more expensive fiberglass?), and labor costs (DIY or professional). 

While you can't know exactly how much your window project will cost until you get a quote from your installer (or retailer), you can still get a good estimate by understanding the 6 major window cost factors.

In this article, we'll go over these cost factors and provide you with handy tables to make estimating your price a breeze.

How Much Do Replacement Windows Cost?

The national average cost for window replacement is around $500 to $1,000 per window, including materials and labor. However, prices can vary widely based on the factors mentioned earlier.

Cost Range Average Cost per Window Common Features Suitable Scenarios
Low-Cost $200 - $600 Basic frames, single or double-pane glass, standard sizes Budget-conscious, rental properties, large quantity replacements
Medium-Cost $750 - $2,500 Quality frames, double or low-E glass, some customization Balance of cost and quality, energy efficiency
High-Cost $2,500 - $5,000+ Premium frames, triple-pane glass, extensive customization High-end homes, historic properties, long-term value

Low-Cost Window Replacement Projects

Low-cost window replacement projects typically fall between $200 and $600 per window. Usually these are very cheap windows you can pick up at Lowes or Home Depot, and you'll either install them yourself or hire a cheap contractor.

One drawback to these windows is that they are often (though not always) sized in 1/2 inch increments, which may not be exact enough to fit properly into your wall opening. If the window is too big or too small, it could cost you thousands of dollars in additional work.

Average Cost per Window: $200 - $600

Common Features of Low-Cost Projects:

  • Basic vinyl or aluminum frames
  • Single-pane glass
  • Standard window sizes and styles
  • No customization
  • DIY installation or cheap contractor

Suitable Scenarios for Low-Cost Projects:

  • If you're on a really tight budget
  • You have a rental properties where better features are unnecessary
  • You're replacing a very large number of windows at once to save on bulk costs

Medium-Cost Window Replacement Projects

Medium-cost window replacement projects usually range from $750 to $2,500 per window.

Average Cost per Window: $750 - $3,000

Common Features of Medium-Cost Projects:

  • Higher-quality vinyl, fiberglass, or composite frames
  • Double-pane and/or low-E glass for better insulation
  • A mix of standard and custom sizes
  • Some customization options for finishes and hardware

Suitable Scenarios for Medium-Cost Projects:

  • Homeowners looking to split the difference between cost and quality
  • Projects where energy efficiency and aesthetics are important
  • Homes in climates where additional insulation is beneficial

High-Cost Window Replacement Projects

High-cost window replacement projects typically cost $3,000 to $5,000 or more per window.

Average Cost per Window: $3,000 - $5,000

Common Features of High-Cost Projects:

  • Premium wood, fiberglass, or composite frames
  • Double-pane or triple pane with high-performance glass with advanced coatings
  • Custom sizes and unique styles
  • Extensive customization options, including specialized finishes and hardware

Suitable Scenarios for High-Cost Projects:

  • Your "forever home".
  • Projects focused on maximizing energy efficiency and noise reduction
  • Homeowners seeking long-term value and high-quality craftsmanship

The 6 Big Factors In Replacement Window Costs

When considering window replacement, several key factors influence the overall cost, including frame material, window type, which glass types you use, what kind of colors and finishes you choose, and which brand you buy.

1. Frame Material

Frame material is a major cost factor because different materials vary considerably in strength, longevity, and how complex they are to manufacture. The most common frame materials are:

  • Vinyl (budget-friendly): Vinyl is very affordable, lasts up to 30 years, and is very low maintenance. It's a great budget option.
  • Wood (expensive): Wood offers a classic look but requires more maintenance to prevent mildew and rot and is generally more expensive.
  • Aluminum (budget friendly): Aluminum is durable and lightweight but one of the least energy-efficient options.
  • Fiberglass (expensive): Fiberglass is very durable (lasting up to 50 years), and can be made to look virtually indistinguishable from wood without the maintenance requirements. It's also the most energy-efficient window frame. Of course, these advantages come with a higher price tag.

2. Window Type

The style of window you choose also affects the cost. Some common types are:

  • Single-Hung and Double-Hung: Traditional styles, with double-hung offering more flexibility but at a higher cost.
  • Casement: Hinged windows that open outward, usually costing more than double-hung windows.
  • Sliding: Slide horizontally to open, typically less expensive.
  • Bay and Bow: Create a protruding feature, adding charm but significantly increasing the cost because of their size and complexity.

3. Customization

Custom features, such as unique shapes, sizes, colors, and finishes, can also drive up the cost. While standard sizes and designs are more budget-friendly, customization allows you to achieve a specific look and functionality tailored to your home.

4. Glass Type

The type of glass impacts both the price and energy efficiency:

  • Single-Pane: Single-pane is the least expensive but offers very poor insulation.
  • Double-Pane: Double-pane is the standard for almost all modern windows. It offers great insulation and noise reduction, and costs more than single-pane.
  • Triple-Pane: Triple-pane offers superior insulation and noise reduction but is the most expensive. This is not typically recommended for residential homes.
  • Low-E Coatings: Low-E coatings are also standard on most modern windows, though you can get windows without them. They improve energy efficiency and (because they're so common) usually won't add much more to your cost.

5. Labor Costs

Installation labor is another significant factor. Costs can vary based on the complexity of the installation, the number of windows being replaced, and local labor rates. While you may be tempted to skimp on an installer, this is almost always a bad idea. Contractor quality varies immensely in the home services industry, and cheap installations not only mean early window failure, but can even damage other parts of your home. Bad installations can drive your energy bills up, cause your windows to fail in just a few years, or cause mold and rot if the window seal fails.

Choosing a reputable installer ensures the job is done correctly, saving you money and time in the long run.

6. Brand

The brand of the windows can also influence the price. High-end brands typically offer better quality and longer warranties but come with a higher price tag. 

Window Replacement Cost by Frame Material

Let's explore the different frame materials available, their costs, and what you can expect in terms of material and labor expenses.
