Does an Egress Window Add Home Value?

Significantly. An egress window converts below-grade space into a legal bedroom, which adds to your home's official bedroom count and finished square footage — the two numbers buyers and appraisers care about most.

In the Twinsburg market, a legal basement bedroom can add $10,000–$20,000 or more to a home's appraised value, well above the $2,500–$4,500 it costs to install the window. It's one of the few basement upgrades that pays for itself several times over at resale.
