How much does a window replacement cost?

Maybe you are getting ready to sell the family home and want it looking the very best before listing it; or you discovered that a lot of your heating and cooling expenses are too high because the windows are old, inefficient, or both; or maybe you are just ready for a mini fixup or entire remodel.

Even if replacing your windows is all you do, especially on an older home, it will add a new updated look to your home. New windows should also pay you back in the form of reducing your energy costs for the home. Manufacturers tend to agree on the need to replace windows after about 20 years, especially on older windows.

Window Replacement Cost

Costs vary across the country depending on a range of factors. The average US home is about 2,700 square feet with four bedrooms or more, so it will likely have at least ten windows.

At an average of $500 per window, expect to pay about $5,000 total, or $10,000 if the window frame openings need any additional work.

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. Don’t go for the lowest price. As Liberty Windows and Siding in Columbia, MD, says, “The quality of window installation company varies widely from business to business, and hiring the wrong contractor can lead to shoddy workmanship that can cause water damage or even rot.”

Frame type

Depending on the age of your existing windows and the absence of any damage (shifting foundation, dry rot, etc.), you might be able to get away with inserting partial replacements into the existing frames. If, however you have windowsill or frame deterioration, a full replacement will be required.

Alternatively, when replacing old windows for cosmetic or energy efficiency reasons, you should consider taking care of all windows. Your exterior siding will also affect the price, costing more for working with brick and stone than vinyl.

Most vendors offer up to four options in window frames. The lowest cost frames are typically vinyl, followed by steel, fiberglass, and wood. Below are the installed costs for a 42”x48” window.

Frame Type Average Cost
Vinyl frames $550 – $850
Composite frames $600 – $900
Wood frames $700 – $1,000
Aluminum frames $700 – $1,000
Clad frames $1,000 – $1,600

  • $550–$850 | Vinyl frames are the most cost-effective type and require little maintenance, but over time the color may fade. LEI Home Enhancements in Wheat Ridge, CO, says, “In order to be considered vinyl all a company needs is 14% vinyl, which causes discoloration upon the rays of sunshine hitting the window. Our vinyl is 100% virgin vinyl, which means the color of the window is the same all around and there is no discoloration or warping from the sun.”
  • $600–$900 | Composite frames are more expensive than vinyl and cheaper than wood frames. They are also have better structural integrity than wood and vinyl and can be painted.
  • $700–$1,000 | 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 great temperature insulation.
  • $700–$1,000 | Aluminum frames, being made from metal, are very durable and strong, low-maintenance, and more affordable when compared to wood, but they also conduct more heat and cold than wood.
  • $1,000–$1,600 | Clad frames are the most expensive option for window frames. Clad frames are 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.

Opening mechanism

For window openings, the most popular options that you can choose between are either casement or double-hung windows.

  • Casement windows open via hinges along the tall edge which allows the windows to open like a door.
  • Double hung windows are comprised of an upper and lower half. These windows open along sliders which allow the top half to slide down and the lower half to slide up. Another option often used for smaller windows in a bathroom, or the top portion of a window over a kitchen sink, is a window hinged at the top that opens outward.
  • Fixed windows cannot be opened.

Energy efficiency

Because the benefits from energy savings will offset some of your investment costs for the lifetime of the replacement windows, we will cover this topic in some detail.

Buy each window to give maximum savings: Different sizes and types of windows can be installed around the home to give the most energy efficiency, i.e., notice which sides of your home get the most direct sunlight or cold winds.

Buy out of season: A leading factor for replacing windows is tied to energy efficiency and savings for prevailing climate where you live, so there will be a time of the year where you could shop out of season. Get windows that keep the house cooler long before summer sets in, and vice versa. You may also get a better price from your contractor if you hire him or her during slower months.

Save 25% of your energy costs: Old windows can become “leaky,” allowing both heat and cold in or out. Put that unnecessary expense toward the cost of new windows. Upgrade or replace your windows with new double or triple pane windows that have either air or argon gas between the panes of glass. This buffer zone, which can be up to an inch deep, results in a reduced temperature transfer when compared to a single pane of glass. Texas Energy Experts in San Antonio, TX, say that Argon in windows impedes the energy transfer process due to its heavier-than-air properties. It acts as an insulator, and it increases the soundproofing of the window. It also reduces the possibility of condensation buildup, eliminates mold potential, and provides an improved R-value.

Further savings and efficiencies can be seen through the addition of a low-E (low emissivity) heat-resistant coating on the glass, and/or by installing mesh screens outside the windows.

Measure insulation effectiveness: Windows can have an R-Value and U-Factor. “An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density” (US Department of Energy). U-value measures the rate of heat transfer, with the lower the number being the better value. In general terms, as the R-value goes up, the U-value will go down. Heat will always flow from hot to cool until both temperatures are the same. This means heat will try to come into your home during the summer months and leave in the winter months.

Noise reduction: An additional side benefit of switching out to either double or triple pane windows is that it will also reduce the noise from outside, with the greatest reduction coming from the wider gap between panes.

Suspended Particle Devices: Windows with these allow the owner to control how much light is coming in through the use of a dimmer switch. SPDs are gaining popularity in everything from residential and commercial window applications to airplane windows and automobile sunroofs. The use of SPD or UV coatings on windows, like those offered by Skyline Windows in New York, could also be a wise choice if you have large windows that allow a lot of sunlight in on wood floors or expensive rugs.

For the final word on energy efficiency, check out www.energystar.gov. Energy Star is a government program launched originally by the Environmental Protection Agency, and now co-managed with additional resources from the Department of Energy. The Energy Star symbol appears on a sticker along with product category ratings and, sometimes, yearly dollar savings. Each region comes with guidelines for the ratings you should look for in windows, skylights, and doors.

Size

The industry standard terminology of measurement for windows is called UI (united inches). The final number is from the addition of the length and the height, or half the window’s perimeter. 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.

Installation and removal costs

Expect to pay $100–$175 per window for installation, and add another $170 per window for weather stripping. This should boil down to $35–$65/hour. Anything other than a regular window can cost more to install, such as skylights, casement windows, bay windows, etc. A bay window can cost up to $7,000 installed. Removal of old windows and transporting them for disposal costs about $70–$250/window.

Tips for hiring your window replacement contractor

  1. If you are fairly good at carpentry and general home repairs, and depending on where you live, you may choose to buy the windows at one of the large national chains of hardware stores. Install costs are close to an average of $100 per window for a professional to do the work. You can elect to do this work yourself, but you could also miss out on identifying and fixing existing dry rot, or other structural issues.
  2. In addition to looking up reviews online, a quick check with the Better Business Bureau can save you from bad workmanship and unethical behavior.
  3. Companies that work exclusively in window replacement can give a large discount on the price of materials bought through their network, like Pro Window Installerz in Riverside, CA, who offer up to 35% off windows they buy directly from the factory.
  4. When getting your top three quotes, ask your vendors if their price includes the disposal of the old windows.
  5. Ask about the company’s warranties. Many companies—like Pueblo Glass and Door in Aurora, CO—offer a 100 % satisfaction guarantee on each job and a lifetime warranty on the labor.
  6. Make sure the contractor you hire is bonded and insured, like St Germain’s Glass Co in Duluth, MN.
  7. When replacing windows on older homes, your installers might discover other issues regarding the structural integrity of the home from damage like dry rot. Be prepared for a possible change in the quote if this happens.
  8. If you are replacing a window that is not a standard size or shape, you can expect there to be a percentage price increase for that window.
