How Much Does Window Replacement Cost?

Replacement windows cost between $64 – $1,600, depending on the type of window and frame. You should plan to pay anywhere from a few hundred to a few thousand dollars for your replacement windows. Your total cost depends mainly on the material, style, energy efficiency features, brand, and customizations you select. Window material is often the biggest cost factor. Depending on what matters most to you about your window, you may be able to save money by going with a more budget-conscious frame material. 

See average prices for each material and what its pros and cons are below. Note that a material having an X doesn’t mean it doesn’t offer that feature at all, just that it’s not one of its strengths.

How Can You Save Money on Replacing Windows?

We know replacement windows are a costly home expense, even if you choose the most budget-friendly materials and design. Luckily, you can save money by buying in bulk, looking for discounts, repairing instead of replacing, and shopping during the offseason. 

Buy in bulk: If you’re purchasing windows for all or part of your home, talk to the manufacturer about a discount for buying in bulk.
Look for brand discounts: Some companies, such as Champion, frequently offer helpful discounts, such as Buy One, Get One Free. 
Repair instead of replace: If you’re replacing a window because the glass is damaged, you may be able to save money by simply repairing or replacing the glass instead of the entire window unit. 
Shop in the offseason: The window industry slows down in winter because few homeowners and installers want to deal with installation when it’s cold out. You may be able to find lower pricing on windows and installation during this offseason since companies are looking for more business. 

If you’re financing windows, don’t assume you’ll have to put money down or deal with high-interest rates. Champion, for example, offers a financing program that has no interest, no money down, and no payments for 12 months.


What Should You Consider When Replacing Your Windows?

There are a lot of options when buying windows. Being that replacement is a high-cost home improvement project, it’s understandable you want to pick the most affordable option with the highest return on investment. We’ve broken down the key things to look at to help make the process easier.

Are Energy Efficiency Windows Worth it?

According to Josh Ramsey, Renewal by Andersen’s Midwest regional training manager, one of the biggest reasons homeowners replace their windows is to increase energy efficiency in rooms with poor temperature regulation.

Though they’re more costly than standard windows, energy-efficient windows help you save money on your energy bills. The U.S. Department of Energy (DOE) and the Environmental Protection Agency’s (EPA) joint program, Energy Star, reports that replacing clear-glass, single-pane windows in a single-story, 2,000-square-foot home with new Energy Star-certified windows can save you $101–$583 per year.

Windows certified by the National Fenestration Rating Council (NFRC) have a label that helps you compare energy-efficient windows on key metrics, such as U-factor, solar heat gain coefficient, visible transmittance, and air leakage. Check out the NFRC’s website for more information on these factors and what to look for.

You’ll get the biggest return from your windows by choosing one with energy-saving features. The Department of Energy reports that heat gain and loss through windows is responsible for 25%–30% of residential heating and cooling energy use. That poor insulation means your HVAC system is working harder to keep your home comfortable, causing your monthly energy bill to rise. 

Choosing an energy-efficient window keeps your home more comfortable, your bills more reasonable, and your HVAC system in better condition. Here are a few things to look for to ensure you get an energy-efficient window that will provide a solid ROI:

  • Argon-gas filling that provides extra insulation between glass layers
  • Double- or triple-pane glass for added insulation
  • Energy Star label that guarantees certification for your climate
  • Low-emissivity (low-e) glass coating to better manage heat transfer

What is the Best Window Frame Material?

Each frame material has its own benefits and drawbacks.

Aluminum window frames are highly durable and budget-friendly. The material is strong, so it fares well in extreme weather conditions. It’s also rot- and mold-resistant. Aluminum windows are less likely to fade and show signs of wear and tear than other options. However, aluminum frames are not energy efficient, and the material conducts heat rapidly.
Composite frames combine fiberglass with other materials, such as laminated wood or plastic. They can mimic the appearance of solid wood while providing more durability and better performance due to the embedded fiberglass needles. Unfortunately, they don’t come in many colors and are susceptible to fading. 
Fiberglass frames are highly durable. They’re stronger than vinyl and resist fading and cracking for longer. Fiberglass windows are excellent for homes that experience extreme weather, because they’re resistant to weather and sharp temperature changes. However, they’re more expensive than most frames. 
Vinyl frames are the most common and affordable window frame material. They’re made of polyvinyl chloride (PVC). Vinyl windows work with almost any home style, have solid energy efficiency ratings, and are a great insulator. They also require little maintenance. However, vinyl isn’t as durable as wooden and aluminum windows.
Wooden windows are highly durable and stylish, though you’ll have to pay a hefty price tag for them. Many homeowners choose wooden frames for their curb appeal. Wood is also a great insulator, so these windows are typically highly energy-efficient. The only downside is that wooden frames require a lot of upkeep, as they’re naturally susceptible to mold, termites, and rotting. 

Ask these questions about the window’s framing material:

Do the frames match my home’s style? 
What is the climate around my home? 
How much maintenance do the frames require?

What Window Style is Right for Your Home?

You’ll want window styles that complement your home’s architecture while staying within your budget. Many contemporary homes have casement or sliding windows. Historic homes often feature double-hung and awning windows, while farmhouse-style homes have bay or bow windows.

What Are Common Window Types and Their Functions?

Read about popular window types below and look for companies that provide windows that match the look of the room(s) you’re upgrading.

Also called arch-top windows or radius windows, arched windows have square bottoms and an arch or half-circle on top.

Arched Window Icon

These windows have hinges at the top of the frame and swing outward from the bottom. They often have a crank or a type of glide hardware. 

These are small windows in your basement that increase natural light and airflow. They run across the top of your home’s foundation and are hinged at the bottom to open at the top. Many homeowners choose to convert basement hoppers into egress windows to act as emergency exits.

basement hopper window icon

Bay windows have a 3D shape that curves outward from your home. Adding a box seat or ledge can transform them into a bookshelf or an additional seating area. Bay windows are angular, while bow windows are more curved.  

bay window icon

This popular window style has a hinge on the side and swings open to the left or right via a crank. Casement windows are often placed in hard-to-reach areas, such as over a kitchen sink or in a bathroom. 

casement window icon

These windows have two locks and open at the top and bottom. They’re often found on high floors.

double hung window icon

Garden windows protrude from your home, creating a space to grow plants and herbs. They’re ideal for a kitchen window.

These windows are translucent, thick blocks of glass. They allow light into the room but obscure the view, which makes them a popular option for basement and bathroom windows

glass block window icon

These oversized windows are floor-to-ceiling accents. They cannot be opened and provide a lot of natural lighting.

picture window icon

Sometimes called geometric windows, shaped windows provide an accent that lets light in where standard windows might not work. Popular shapes include half-round, round, eclipse, triangles, and trapezoids.

These windows function similarly to double-hung windows, but they only open on one end. They’re also typically smaller than double-hung windows. 

single hung window icon

Consider the following when thinking about what window type you need:

How do I need the window to function?
What size window is being installed?
What room are the windows being installed in?
How will they look in that room?
Do I want the windows for style, energy efficiency, or both?

Do Your Windows Offer Warranty Coverage?

Window manufacturers include warranties on their products to protect your investment. The length and stipulations of these warranties vary by product. High-end options, such as wood windows, typically come with comprehensive warranties, while vinyl windows may come with shorter, less thorough coverage. Window coverage usually includes a manufacturer’s warranty that covers the glass, frame, hardware, and other materials, as well as a labor warranty that covers installation workmanship. If you hire a third-party installer, your labor warranty will come from this company rather than the manufacturer. Always get a window warranty. 

Warranty coverage can range from a couple of years to the product’s lifetime. Unfortunately, lifetime warranties are not standard in the windows industry. In our survey of 1,000 homeowners, 37% said they received only a two- to five-year warranty. However, 91% of homeowners said their warranty was fulfilled when they made a claim. An installer that offers lifetime warranties on its windows or doors, such as Castle, is a secure investment.

What Window Companies Have Good Customer Reviews?

Reading customer reviews on popular sites such as Better Business Bureau (BBB), Trustpilot, and Google can help you understand buyers’ experiences with the companies you’re interested in. Take note of the pros and cons each reviewer shares. Our expert from Renewal by Andersen, Josh Ramsey, recommends looking for companies that have one-stop accountability, meaning their products and services are primarily in-house rather than contracted out. He says providing an in-home consultation is a positive sign of professionalism and good customer service.

Many customers will also mention whether a company stands behind its work with its warranties, and how helpful customer service reps are. You may want to consider a different installer if you notice many negative reviews.

Who is the Best Window Installer?

Finding a reputable professional window installer will ensure your project is completed properly, safely, and efficiently. Many major window manufacturers provide networks of installers certified to work with their products. Using a contractor your window brand recommends prevents problems later on because the manufacturer can’t blame the installer for issues or vice versa. We recommend getting multiple free quotes and checking the American Window and Door Institute to ensure your installer is certified.

Your pricing estimate should include the window brand and model, number of windows, size, and type, plus any add-on features. Installation details should be noted, and labor and material costs should be broken down separately.


How Do I Find a Window Installer Near Me?

Many companies offer professional window installation. One way to narrow your options is to look for installers who are certified for the particular window brand you want. You should also confirm which companies service your address.

Most homeowners we surveyed (46%) opted to hire a local contractor, citing that they were scared to make a mistake, wanted to protect their windows with a warranty, or simply didn’t want to deal with the hassle of installing windows themselves.

FAQs About Window Replacement Companies

What type of window is the most energy efficient?

Wood windows are the most energy efficient because they insulate better than other materials. However, they require more upkeep than vinyl, aluminum, or hybrid windows. Any window with a low-e coating should be an excellent choice for energy-efficiency. 

Which replacement windows last the longest?

Fiberglass windows often last the longest due to how durable and weather-resistant they are. They’re also the least likely material to develop seal failure. Fiberglass windows typically come with comprehensive warranty coverage because the manufacturer knows it’s a long-lasting, high-quality material. Expect to pay more for fiberglass, though the energy efficiency and longevity you get out of the window may actually save you money in the long run. 

What is the best alternative to vinyl windows?

We recommend composite windows as the best alternative to vinyl windows. Though composite windows are more expensive than vinyl, they offer greater energy efficiency and durability without being as expensive as fiberglass or wood windows. 

How often should you replace windows?

You should replace your windows roughly every 20–30 years. However, this time frame depends on the materials used for your windows, the weather conditions where you live, and the windows’ functionality.
