Egress Window Installation Cost
Egress window installation cost should range from $1,300 to $6,500 fully installed - this price assumes that you have no opening in your basement wall and have to start the project from scratch. If there is an existing window opening, the cost goes down dramatically - perhaps the opening only needs to be increased a bit for code and a replacement window needs to be installed. The majority of the cost here is the price of the installation.

Ready The Exterior Area
The outside area often, but not always, has to be readied by excavating and clearing earth from near where the egress window will be placed. By code (which varies by county or city), the clear area must be 3 feet by 3 feet to allow the window to swing open without any encumbrances. This usually means having the installer or company rent a small back hoe or other machinery to clear the space. Of course, if your project is do it yourself, you can probably just dig it out yourself (which costs nothing but your sweat and labor). More likely, however, you will want to rent some equipment to clear the space. This might cost $200 or so, depending on where you rent the equipment from. In total, our estimated cost range is $0 to $1500.

Create The Rough Opening
Creating the rough opening means cutting a hole in the basement that will serve as the perimeter of the window frame. While this can be a relatively simple job, it certainly demands an understanding of the structural foundation of the home. Importantly, the contractor or installer must make sure that they do not hit any water or electrical lines that may be in the wall. While this technically can be done by the home owners themselves, it is probably best left to a professional. The rough opening cost projection is $400 to $1000.

Egress Window Installation Cost: Basement Window
Framing out the basement window is essentially like new construction installation. So, the opening must be framed out and the window will be set in the new frame and shimmed for a plumb fit. Installers may opt for a sill pan and moisture barrier wrap around the opening to prevent any future water damage. Next, the spaces around the window is filled with foam or traditional insulation and the window is caulked and sealed inside and out. All in all, a relatively simple part of the process. Our estimated cost range is $200 to $500.

Cost Of The Window
The most common style of basement window includes casement, slider and double hung. Of course, these will vary in price depending on the frame material. Specifically, the five main frame materials include vinyl, fiberglass, composite, aluminum, and wood. While vinyl is going to be the least expensive, wood clad is often going to be the most expensive. Additional cost factor include the size of the window, glass package, and any upgrades you may opt for. For our purposes, we put this cost at $500 to $1500.

Egress Window Installation Cost: Landscaping
The final step is a big one and can be very simple, very complex, or somewhere in between. On the simple side is installing a pre-made window well. So, the window well will have to be placed into the excavated area to secure the area from weather, earthquakes, and natural movement of the ground. Essentially, anything that would fill in that space over time.
On the complex side of things is a large outside area that can be framed concrete, gardens, or any number of design features and elements. In these cases, the exterior landscaping truly adds to the overall aesthetic of the home and can also add significant value to the home as well. For the purposes of our egress window installation cost calculator, we put the estimated cost range here at $200 to $2000.

Basement Window Replacement Cost Question
Bill, what would you say is a fair and credible price to spend to replace our current basement window? Currently, we have an old wood clad casement. They will need to do some minor work to the window well. However, we are probably going to swap it out for a new one - exact same size as the old one.

[Site Editor's Answer]
Eliza, providing quotes isn't always easy to do. However, if I were to guess, I'd say to swap out the window with an energy efficient vinyl casement from say Marvin fiberglass windows, you might be looking at $1800. Plus another $500 for the well and $300 in labor. So, that would total about $2600 total. My standing advice is to collect some price quotes from local companies and then some over the project estimates and we can look at them together and find the one that makes the most sense. If you went with a vinyl window, you could probably subtract about $600 from that, bringing your total to $2000.
