Project Steps

The following steps are involved in building out an egress window. Please see our page on what are egress windows for a more comprehensive breakdown on the basics and the project steps involved.

Step 1. Dig Out The Exterior: This step is pretty self explanatory. Whomever is doing the work must clear enough space for the window to open (as with a casement) and for a normal sized adult to exit the window and climb to safety in the event of an emergency. Often, this step requires a backhoe or excavator in order to clear the space. This step can be relatively simple if the window sits at or slightly above ground level. If the window opening is below ground, then certainly there is quite a bit of excavating involved.

Step 2. Install The Retaining Structure: As soon as the outside area is all set to go, the company doing the work needs to secure it. This can be accomplished with a pre-made metal half round "wall" that comes with a ladder up, or it can be any other intricate designs. Some of these outside spaces are gorgeous and add to the overall look of the home.

Basement Egress Window Cost

Hi Bill, I was quoted by an OKNA licensed installer a price of $4,000 to install four small basement windows. I don't know if they're 400 or 500 series (I think 400) or the cost of windows versus labor - it is just one number on the quote ($4,000). I'll go back to them for details but it seems really expensive for small slider windows (33" x 18").

In your opinion, what should be the cost to add an egress window in today's market environment. What do you think? Is $1,000 per expensive? Sure seems so to me. Thanks.

[Site Editor's Answer]

Scott, it's difficult to say because installing in basement windows can be tricky: and yes small openings might run $400 or $500 for the window itself. That would be a steep install price, but it doesn't necessarily mean it's out of line. More bids will answer the question - let me know if you'd like my list of brands and options. I think you need to check out our egress window calculator for ballpark pricing. That and to collect a handful of bids - this will tell you the fair market price.
