Other Window Cost Factors
There are many other factors to consider when planning a budget for new windows. Considerations like glass type, size, which floor of the house the window is going in, and many other factors impact the total price.
Glass Type
Glass type impacts both the installation cost and long-term energy costs. Single-pane windows are the least expensive but have the worst insulating properties, so they cost the most in terms of energy use and carbon footprint.
When comparing the pros and cons of double-pane windows, note that you can save up to 24% in cold climates during the winter and up to 18% in hot climates during the summer. You'll pay more for double-pane windows, but they will pay for themselves over time; Double-pane windows cost more to install but cost less in energy wastage. A triple-pane window runs for 15% to 40% more than a double-pane one, but it further reduces heat loss.
Size
The bigger the window, the more it costs. Bathroom windows are often the least expensive, as they tend to be small, often sized at 1-1/2-by-2-by-3 feet.
Living room windows are often more expensive because they're larger, and because this is where the family entertains or spends most of its time, these windows are decorative and functional. While a window can be any size, a standard picture window is often 6 feet by 6 feet. This is also where you'll commonly find bay or bow windows, which are large, tall windows made from multiple sheets of glass and are expensive to install.
Second or Third Floor
Be aware that units above the first floor may be more expensive because of access issues. The second floor and higher require additional equipment, such as scaffolding, ladders, and safety harnesses. Not only does the cost of equipment increase the price, but the project will also require more labor.
Large Units & Window Wells
Window walls range from $700 to $1,600 per linear foot for the materials and installation. These are excellent additions to highlight views and scenery but require the right structural supports.
New Construction vs. Replacement
New construction windows run anywhere from $85 to $1,400. Designed for new construction and during remodels where the stud-framing is exposed, they attach directly to the studs via a flange called a nail fin frame.
Replacement windows cost $300 to $2,100 depending on the size, installation requirements, and material. Specialty types, such as glass-block and large-picture styles, can run upwards of $2,500 or more.
Full-Frame vs. Inserts or Retrofits
Full-frame windows are about 10% to 15% more than a retrofit style. Expect to pay an additional $50 to $100 per unit for installation prices.
Retrofit, also called inserts, uses the existing frame and trim for a quicker job.
Full-frame types require removing the old frame and putting in a new frame and trim. New trim requires staining after the installation to match your current trim.
Installing a Window in an Existing Wall
While you can expect to spend anywhere from $1,000 to $5,000, or more, per window, no two projects are the same. This type of work requires a combination of framing, siding, finishing work, and sometimes electrical and plumbing rerouting.
Factors that affect new installations in existing walls include:
