There are several reasons to consider replacing the windows in your home. You might be a new homeowner who prefers to upgrade to modern windows and bolster energy efficiency. You might be ready to sell your home and want to increase curb appeal. Or you might have damaged windows that need repair.

No matter the reason, you have window replacement options available. Window replacement types vary in labor and material costs. They depend on your preferences and how many windows you want to replace. Keep reading to learn the types of replacement windows and which one might work for you.

Key takeaways

Full-frame window replacement is the most expensive option, but it may be necessary depending on the state of your window.

The type of glass pane can impact the cost of your window replacement, but double-pane energy-efficient windows are worth the extra cost.

Aluminum, composite and fiberglass are the most durable and energy-efficient frame options, while vinyl is more affordable and widely available.

Window installation type

“The cost [of window replacement] varies on whether you opt for an existing frame installation, which is less expensive, or a full-frame installation, which involves removing the existing window and frame completely, thus requiring more labor and materials,” said Norstone USA Director Rassan Grant, a building materials executive with more than 17 years of experience based in Central Florida.

You can pick from three types of window replacements:

  • Full-frame: With full-frame replacements, you remove and replace the entire window, including the frame, sill and trim.
  • Pocket/retrofit: Another option is to use pocket, or retrofit, windows. Rather than installing a new frame, the window manufacturer creates an insert to place inside the existing frame.
  • Sash-only: Sash-only window replacement involves a portion of the window or its hardware.

The table below summarizes the different types of window replacements, when to consider them and their pros and cons.

Full-frame

Installing new windows on a home.

A full-frame replacement makes the most sense if you’re replacing several windows, want to change your framing material, increase window efficiency, or have rotting or damaged window frames.

pro tip

  • If you can get away with retrofitting windows, you’ll save up to $20,000 or more on your window replacement project. So, always get a second opinion on whether your window frame is okay to reuse.

It involves removing all parts of the window, from the frame to the interior trim. This replacement method offers the ability to insulate your window better and the option to reserve or increase the glazing area (glass), which leads to a better view.

One downside to full-frame replacement is cost. It requires the most work and is usually the most expensive option, though window replacement costs will vary based on the material, size and location of the window and labor involved.

Residual costs can also add up because you must replace your home’s siding around the window. You may incur additional costs to install the trim and sill and paint the area.

I recommend Andersen Windows, Champion Windows or Universal Windows for full-frame replacement.

Pocket (retrofit)

Window insert replacement.

Pocket window replacements, or retrofit window replacements, make the most sense if the window frame is in good condition and there’s no rotting, mold or other damage to the window. A retrofit replacement can save time and money because the installer fits a new window into the original frame.

If your house exterior is stucco or brick, you might consider a pocket window replacement, as replacing these materials can be more difficult and expensive with a full-frame replacement.

However, during a pocket window replacement, you reduce the size of the window’s glass area. This replacement method creates a smaller frame, which allows the new window to slide into the old frame. You end up with a slightly smaller window, something you may feel the effects of when you open the new window to get fresh air.

Also, pocket replacement doesn’t let you add insulation around your window or remove any rot or mold inside the frame. If you remove your current windows and see rot or damage issues that need to be addressed, you might not be able to proceed with a pocket replacement.

I recommend Andersen Windows, Champion Windows or Window World for a window insert replacement.

Sash-only

The sash portion of the window surrounds the glass and grids. If you discover a functional problem with a window when you open it, close it or lock it — or if the window feels drafty — you might have a sash problem.

The plus side of a sash-only replacement is affordability. If the main issue is hardware, such as locks, jambs, cranks or hinges, replacement only involves a small portion of the window. Parts will cost less than any other replacement option. Labor should also cost less, and you may be able to do repairs yourself.

One downside of a sash-only repair, however, is diagnosing the issue correctly. There is always a chance your problem is a larger one. It may be beneficial to have an installer examine the window, determine the problem and suggest possible solutions.

Window frame materials

Window manufacturers make frames of vinyl, aluminum, wood, composite and fiberglass. These materials have different properties and price points. The framing material you choose is always a factor in the durability and cost of window replacement.

“Vinyl window frames typically last about 20 years, while fiberglass frames can last up to 50 years,” Grant said. When you have the opportunity to replace a window, that’s the right time to evaluate your framing material and if it’s serving you.

Aluminum

Aluminum framing is affordable and durable. Extruded aluminum provides even more strength, said Michael Wandschneider, the director of product management at Marvin Windows.

“We only use extruded aluminum, which is much thicker than standard roll-form aluminum,” Wandschneider says. “The added strength and durability of extruded aluminum benefit the overall performance of windows and doors.”

Composite

Composite framing is a mix of wood, fiberglass or other materials. It is low-maintenance, energy-efficient and affordable.

Fiberglass

Fiberglass provides the highest energy efficiency while also being low maintenance. It has the longest lifespan and is the most expensive of all the available framing materials.

Vinyl

Typically the least expensive material, vinyl windows can be made from PVC and are low maintenance. However, extreme heat can soften vinyl and cold temperatures can make it brittle.

Another downside is color. According to Wandschneider, “Vinyl windows tend to have limited color choices due to heat damage risks with darker colors.”

Wood

Wooden windows may have all-wood interiors and exteriors or aluminum-clad or fiberglass exteriors. This combination helps maintain the wood’s traditional appearance while improving its durability.

Wood is beautiful, natural and energy efficient, but it may rot, mold or warp, making window repair costly.

Window glass type

If energy conservation is your goal or you want to improve your home’s aesthetic, glass can play a part. The more panes of glass you replace, the more expensive the window replacement will be. Specially coated and tinted glass will cost more.

Single pane

The least expensive type of pane, a single-pane window, provides little thermal protection and less energy efficiency. Most window replacement companies won’t even offer this as an option anymore because it is so inefficient.

Double pane

Double-pane windows usually deliver quality insulation and energy savings. However, they are more expensive to install. This is the most common type of glass pane on the market.

Triple pane

Triple-pane windows offer top energy efficiency and insulation from sound and heat. A triple-pane window replacement is the most expensive option of the glass types.

There’s also a structural issue to think about. “Adding a third pane of glass increases the thickness and weight of the window unit, so your home may require additional structural work to support the window,” Wandschneider said.

Low-E coating

Low-emissivity (low-E) coatings are becoming increasingly popular for energy efficiency. These coatings, which come in different strengths, insulate glass to keep radiant heat in or out while providing UV-ray protection. They are more expensive to install.

Reflective film

Although reflective film helps keep rooms cooler by blocking radiant heat, it also blocks out light. Windows with reflective film look like mirrors. Because the film blocks natural light, homeowners may have to use more indoor electric lighting instead, costing them more in power bills.

Tinted glass

Tinted glass refers to gray or bronze tint and works similarly to reflective film, but it can better block radiant heat. This makes cooling less burdensome while allowing in light. Tinted glass can reduce the transmittance of light by 30% compared to clear glass.

How to save on window replacement

Here are some ways to potentially save on window replacement:

  1. Evaluate the type of window replacement needed or consult a professional.
  2. Get at least three quotes for the work.
  3. Perform a bulk window replacement.
  4. Complete the window replacement during the cooler fall and winter months.
  5. Ask the manufacturer for deals or discounts.
  6. Choose Energy Star-certified windows.

When to replace your windows

Assessing all your windows to determine their condition is a good place to start. You can find out how old your windows are using the date your home was built or individual window replacement receipts.

Grant said the following signs indicate it’s time for new windows:

Structural issues

Structural issues that may result in a safety hazard are paramount. Replace windows whenever safety is an issue or if you’re dissatisfied with your windows’ look, feel and performance. For example:

  • Noise penetration: Increased outdoor noise suggests your windows might not seal correctly.
  • Operational difficulties: If windows become difficult to open or close, they need replacement.
  • Physical damage: Visible damage, such as cracks, warping or water stains, is a direct indicator that new windows are needed.

To properly diagnose and address the problem, have your windows surveyed by a professional.

Decreased energy efficiency

Feeling drafts or noticing a spike in energy bills can indicate poor window performance.

  • You might see condensation on your windows or feel air rushing around the windows.
  • If you notice an increase in your heating or cooling bill, it may be time to replace your windows.

Aesthetic deterioration

Outdated or damaged windows can detract from your home’s curb appeal and might necessitate replacement. Special coatings and decorative glass can help deflect radiant heat and keep your home looking its best. Large-scale window replacement can also increase your home’s value and curb appeal.
