Replacement Window Prices By Material

The average cost for a standard-size vinyl window that is double-hung, double-pane, and energy-efficient is between $400 and $650 per window installation. For a wood replacement window, expect to pay between $700 and $1,000 including installation.

Here are the average replacement window prices by frame material:

Replacement Window Prices
Frame Type Average Cost
Vinyl $100 – $850
Composite $280 – $900
Wood $200 – $1,000
Aluminum $80 – $1,400
Fiberglass $150 – $1,400

Vinyl Window Replacement Cost

Vinyl window replacement costs range from $100 to $850 each with most homeowners paying between $400 and $600 for a double-hung, double-pane, and energy-efficient window. Vinyl frames are the most cost-effective type of window frame and require little maintenance, but over time the color may fade.

Replacement Wooden Windows Cost

For a wood replacement window, expect to pay between $200 and $1,000, or $700 on average including installation. Wood frames can contract or swell because of the exterior elements, and they need maintenance to keep them in tiptop shape, but they do provide excellent temperature insulation.

Composite Replacement Windows Cost

Composite window frames are more expensive than vinyl and cheaper than wood frames, costing $280 to $900 each. They also have better structural integrity than wood and vinyl and can be painted.

Aluminum Windows Cost

Replacement aluminum windows range from $80 to $1,400 each depending on the size, and number of panes. Aluminum window frames, being made from metal, are very durable and robust, low-maintenance, and more affordable when compared to wood. However, they also conduct more heat and cold than wood.

Clad Windows Cost

Clad window frames are the most expensive option for window frames at $300 to $2,000 each. With a vinyl shell over a wood or aluminum frame, they are low-maintenance. With the wood interior frame option, there is also more efficiency in energy reduction, because less heat or cold will pass from the outside.

Fiberglass Windows Cost

Fiberglass windows cost $150 to $1,400 each and are able to endure extremes in both hot and cold temperatures. Fiberglass windows are energy efficient and can offer the look of painted wood without the maintenance associated with wood windows.

Single-Hung Replacement Windows

A typical single-hung window costs $100 to $500 on average, and is one of the most popular choices due to price. A single-hung window keeps the top half of the window fixed in place and the bottom half of the window moves up and down.

Double-Hung Window Prices

A typical double-hung window costs on average $150 to $600. A double-hung window allows both the top and bottom halves to move up and down. If you opt for the more expensive version, the top and bottom halves also swing inward.

Picture Window Replacement Cost

Depending on the size, a fixed or picture window will cost $80 to $500, on average. Fixed windows only have one pane of glass and do not open. Picture windows often require custom sizing which can increase your cost.

Casement or Awning Window Prices

A typical casement window costs between $200 and $1,000, depending on the framing material. These windows open from left to right by using a hand crank, allowing a wide opening. Casement windows are often found near basements or ceilings. A casement style that's hinged to the top is called an awning window, while a hopper is hinged to the bottom.

Bay and Bow Window Costs

Both bay and bow windows start at around $500 and can go all the way to $10,000+. Both types extend outward from the wall and require framing, flashing, and roofing extras. Typically most homes will only have one or two bay windows on the front of the house, and possibly a third on the rear of the home facing into the backyard.

  • Bay Window – Costing $500 to $2,500, a bay window is a series of three windows. Generally, there is a large window in the middle with a smaller window on each side, and it extends outward from the house.
  • Bow Window – Costing $1,500 to $5,000, a bow window usually contains five or more individual windows that are placed in a curved setting.

Sliding Replacement Windows

Depending on the size, sliding windows typically cost around $150 to $600. These windows work just like single- or double-hung windows but move horizontally instead of vertically. They come in many different types and styles, allowing either one side or both sides of the window to move.

Basement Window Replacement Cost

Many basement windows are small and affordable. The average prices we see range from $50 to $500 per window. Typically, these will be fixed windows that do not open for maximum insulation.

Egress Windows Installation Cost

Egress windows vary quite a bit and can get expensive. You can expect to pay around $500 to $2,500 for an egress window. If you choose to place an egress window in a basement, you can expect to pay much more, with prices starting at $2,000 and going up to $5,000. An egress window is required by code if you plan to put a bedroom in the basement. These windows can also be used as an escape route during a fire or natural disaster.

Glass Block Windows Cost

The range of costs for glass block windows span from around $80 to $800, and the prices are generally dictated by the size of the window being installed or built. Extra features like constructing it on a curve will also add to the project cost. Glass block windows are often selected for bathrooms because of the privacy afforded by them.

Folding Windows Cost

Folding windows are not as common as traditional windows. Their product cost ranges from $1,500 to $4,800, but your overall project cost will rise well beyond that because of the install costs for this specialty upgrade, which rides in a trench in the sill to facilitate their opening and closing. These make an excellent choice of windows if you love having an unobstructed view.

Custom Replacement Windows Cost

Custom windows can get expensive but typically run from $300 to well over $3,000—just for the window and not including installation. Custom windows are typically only used when the window openings are an irregular size or not uniform as seen in very old homes. Your contractor will measure and order your custom windows directly from the manufacturer and then install them.

Average Cost To Replace Windows

The average cost to replace windows is between $400 to $800 per window with most homeowners spending around $550 each including installation. Given the average home will likely have around twenty windows, you can expect to pay about $8,000 to $12,000 to replace them all, and more if the window frame openings need any additional work or replacement.

Cost To Install Replacement Windows

The typical cost to install replacement windows is $403 to $631 per window which includes professional labor. You’ll pay more if your home is a two-story home, and more again if the windows are triple glazed or filled with argon gas. Replacing your windows will add an updated look to your home and should also pay you back in the form of reducing your energy costs.

Labor Cost to Install Replacement Windows

The labor cost to install a standard-size vinyl replacement window is between $159 and $258. Expect to pay about $35 to $80 to remove and replace single-pane window glass set in putty or vinyl stops, or $100 to $175 per double-pane window. Add another $170 per window to install weather stripping.

This should boil down to a labor cost of $35 to $65 per hour to install replacement windows. Anything other than a regular window can cost more to install, such as skylights, casement windows, bay windows, windows on the second or third story, etc. Removal of old windows and transporting them for disposal costs about $70 to $250 per window.

Cost of Replacing Windows by Size

Regardless of the frame type or opening mechanism, the lowest cost replacement project is where you have windows placed into an opening of the same size as the original window, without the need for any extra time and effort to create a larger opening. With so many options, styles, and sizes available, the best way to get an exact price is by contacting a window installer near you today. The most common window sizes are:

  • Wood - 18 to 60” wide and 18” to 48: tall
  • Vinyl - 18” to 48” wide and 18” to 36” tall

Single-Pane Window Replacement Cost

The average cost to replace a single-pane window is $288 to $460. These are the most basic windows with the least insulation that are typically found in older homes. Standard single-pane glass can be purchased for as little as $2.50 per square foot.

Single-Pane Vs. Double-Pane Window Replacement Cost

Double-Pane Window Replacement Cost

The average cost to replace a double-hung, double-pane window ranges from $450 to $1,000. A double-pane vinyl window ranges from $450 to $600 to install, while a double-pane wood replacement window costs between $800 and $1,000.

Window Cost if Frames Are Rotting

It’s much cheaper to just replace the glass in a window rather than the entire wood frame plus glass, which must be done if the frames are rotting or warping. The final price will be about double the cost of replacing the glass. See the difference in framing material costs in our comparison table above.

Cost to Replace Windows in an Old House

The average cost to replace windows in an old house is $800 to $3,000 per window which is double or triple standard pricing. Factors that affect your price include rotten wooden frames, the need for custom window sizes, the need to upgrade to current standards, and removing any counterweights. Depending on the current state of the home, you may be able to keep the current frame in place and just swap on the glass for an average cost of $350 per window.

Full Frame Window Cost vs. Retrofit Replacement

The vast majority of windows are available as full-frame (new construction) or replacement windows. Replacement retrofit windows are available in custom sizes, whereas full frame windows are generally only available in standard sizes which are installed into an existing opening.

Full-Frame Vs Retrofit Window Cost
Full-Frame Windows Replacement Windows
Install is between $150 and $1,000 per window Install is between $100 and $300 per window
Only available in standard sizes Custom sizes available
Requires drywall removed to expose studs Set into existing framing
12.5% cheaper for windows, a lot more to install 12.5% more for windows, a lot less to install
Needed if the frame is damaged or in remodeling Good for replacement or updating home
Extra costs from an interior and exterior wall finish No additional costs from stripping back walls

Full-Frame Window Replacement Cost

A full-frame window is a new window in a frame with a sash. An installed full-frame window will cost $150 to $1,000 per window for professional installation and is only available in standard sizes.

The full frame option requires the wood that surrounds it to be nailed into the studs in the wall. The opening will have to be stripped down to the studs by cutting the drywall on the interior wall, replacing the studs around the window, and finishing out the drywall once the new window has been installed. In most cases, this will also require removing a portion of the siding on the exterior of the home, which will also need to be finished out when the window is in place; and if you have brick on the outside, your costs will go up significantly.

Cost To Install Retrofit Windows

A retrofit replacement window is a window that fits inside an existing frame in the home. A retrofit replacement window will cost $100 to $300 each and is much easier for a professional to install. Retrofit windows are an excellent choice when you're updating your home.

Energy-Efficient Window Replacements

Most Energy Star rated windows will carry a rating that indicates the rate of insulation performance (called the U-Factor, generally measuring between 0.30 and 0.60), and a rating to show how well the window blocks the heat of the sun (called the solar heat gain coefficient, which measures between 0.27 and 0.40).

There can be an effective reduction of heat loss of between 30% to 40% achieved by upgrading to products that carry an R-value of 5, and a U-factor in the region of 0.15. Energy.gov has a table which details the most efficient windows. However, the cost benefits may not be realized to where the savings cover the cost of the upgrade, because it could take between 18 to 20 years to break even.

According to EnergyStar, “Energy Star certified windows can lower your energy bill by an average of 12 percent. That’s about $27 to $111 per year for a 2,000-square-foot single-story home with storm windows or double-pane windows and $126 to $465 if your home has just single-pane windows.”

Energy-Efficient Windows Tax Credits

According to the US Department of Energy website EnergyStar, “Tax credits for residential energy efficiency have now expired. The tax credit for builders of energy efficient homes and tax deductions for energy efficient commercial buildings have also expired.”

Frequently Asked Questions

How Much is Window Glass Replacement?

Window glass replacement costs $150 to $500 on average, depending on the size and type. Installers charge $35 to $75 per hour, and the glass itself costs $30 to $100. These costs will rise if argon gas has to be injected between the glass, and even more if the seals need to be replaced.

Are Replacement Windows Worth The Cost?

Replacement windows are worth the cost if your future energy savings are high, you will remain in the home for about 20 years, or if having newer, more energy efficient windows will help sell your home faster. In most cases, homeowners will see a 70% return on investment for the project costs upon the sale of a house with upgraded windows.

How Often Should You Replace Windows?

Manufacturers tend to agree on the need to replace windows after about 20 years, especially older windows. Today, windows are warrantied anywhere from 5 to 20 years, and some are even covered for as long as you own the home. The following is an additional set of criteria you could consider.

  • Poor window insulation, which increases energy bills
  • Poor sound insulation
  • Failing opening mechanisms
  • Warping or rotting window frames
  • Ugly windows won’t sell a home well - recoup a return of around 70% on the sale with new windows
  • Foggy double-paned windows

How Can I Get The Lowest Cost On Window Replacements?

The lowest cost window will likely provide the least insulation, but keep in mind that you can save by

  • Installing fixed or picture windows
  • Installing one big window rather than multiple smaller windows
  • Installing in the offseason
  • Using builder grade or contractor grade windows rather than architectural grade
  • Using standard sizes and shapes over custom products
  • Not sourcing windows from a dealer that only stocks one brand

How Much Does A Mobile Home Replacement Window Cost?

A mobile home replacement window costs as high as $300 from some vendors. Home Depot offers Tafco mobile home windows priced between $61 and $154 each.

How Much Is A Condo Window Replacement?

Some condo HOAs have specific rules on the look and type of windows allowed in the home. The costs for most windows in average-priced condos will average somewhere around $500, and more for higher-end condos.

What Is The Cost Of Replacing Windows And Frames?

Expect to pay an additional 50% to 100% if the frames need to be replaced before new windows are installed. Generally, unless the home is really old with original windows, the damage is often localized to one side of the house, so not every window will incur the extra cost.

How Much Is It To Swap Out Windows And Doors Together?

The bigger the spend with a contractor, the higher the likelihood there is for discounts. The caveat to looking for a lower cost from a package deal is that you are restricted by the types of product that vendor carries, and you could end up with windows you love and doors you are less keen on.

How Much Does Window Disposal Cost?

In the bid from your contractor, you may see a line item for old window disposal with costs ranging from $50 to $80 per cubic yard as well as a $30 to $40 per hour charge to load up a trailer with the materials and drive it to the appropriate dump.

DIY Vs. Hiring a Pro

Replacing the windows in your home is not a project for the faint of heart, and even more daunting of a task if you have a two-story house. There are many different possible failure points where you could easily end up with having invested many frustrating weekends. In the worst-case scenario, you need a professional to come to your home to redo the installation. When you hire the right professionals to do the work, it will be done fast and flawlessly.

Why Hire a Professional?

The task of replacing the windows in your home is not as straightforward as it may appear in a YouTube video. Advantages of hiring professional window installer include:

  • Excellent work – This is a craft that the professionals you hire have spent years learning and perfecting. Each window will be installed with no gaps left for heat transfer to keep the climate in your home just the way you want it.
  • Equipment and tools – Professional window installers will have all the tools required to install your windows.
  • Better prices – Professional installers typically have access to better materials and better prices than a member of the public.
  • Faster – Professional window installers will be 8 to 10 times faster than the average homeowner who has decided to do the work themselves.
  • Cleanup – When the last window has been installed, and everything looks perfect, your installation team will load up the original windows and cart them off to be disposed of properly.
  • Issues – In addition to being able to measure everything accurately before any windows are ordered, they will also know how to deal with situations like rotting wood, and mold, as well as do the work, so it complies with any city ordinances, HOA rules, or building codes specific to your area.

Getting a Professional Window Replacement Quote

As with any home improvement project, get between 3 to 5 cost estimates after you research potential contractors to do the work. You should see very similar elements on quotes from top professionals, and those elements include the following:

  • Before Installation – Any design costs or setup costs.
  • During Installation – Specific costs associated with each window and expenses for any potential issues they might incur once the studs are exposed—like dealing with mold, rotten or damaged structural elements, and any costs related to insulation or weatherproofing.
  • After Installation – The costs associated with removing the old windows and any construction debris and their proper disposal.

Along with the quotes from each potential contractor, you can ask for an electronic or paper copy of the guarantee the windows and the installation come with.
