New windows are a large expense and a decision homeowners will have to live with for decades, so getting it right is essential.
We’ll cover basic window styles and their costs next, but first you should know that you have three main options for replacement windows: insert or pocket windows, full-frame replacements and sash kits:
Insert/Pocket windows: these are designed as replacement windows. The interior trim and old window sashes are removed. If the original window frame is in good condition, it can remain.
The replacement window is inserted into the pocket space left by the old sashes, and it is secured to the side jambs.
Insert windows cost more to install. Because the window fits into an existing window frame, there is more framing and slightly less window pane than with full-frame windows. They are installed from inside the house.
Full-frame windows: these are also called new construction windows. They have a nailing fin around the perimeter used to secure them to the house from the outside of the home before the nailing fin is covered by siding and trim.
Full-frame windows are more air-tight than replacement windows, but are only a cost-effective solution if you’re also replacing your home’s siding.
Sash kits: The sashes are the moving parts of a window – glass surrounded by a wood frame. Sash kits are brand-specific, so they’re used when replacing a damaged window rather than a house full of old windows. Sash kits are made for a very limited number of window brands and series.
On average, you can expect to pay between $450 and $850 to install a new vinyl replacement window. This translates to a typical project cost of $4,500 to $8,500 to install/replace 10 vinyl windows in a typical house.
Note: Your home’s location and local real estate prices and/or local economy/cost of living, window accessibility (1st floor vs. 3rd floor) and scope of additional work, window quality, and project size will materially impact costs.
Below we list total average per-window costs for popular residential options:
- Basic aluminum: $300-$525
- Composite (See materials below): $325-$700
- Basic vinyl: $350-$600
- Better vinyl: $475-$825
- Basic wood: $500-$850
- Fiberglass: $600-$900
- Better wood: $700-$1,000
- Best wood: $900-$1,350 and up
Cost of Materials:
Let’s overview material costs by basic, better, and best window quality.
- Basic windows: $85-$325
- Better windows: $325-$800
- Best windows: $550-$1,500
- Fixed (non-opening) windows: 15%-30% less than windows that open and close.
- Bay and Bow windows: 2-4 times the cost of standard windows depending on window types used to construct the assembly. For example, a bay window might include a large fixed window with 1 or 2 smaller fixed or moving windows on either side.
