An egress window is a large, operable window sized to serve as an emergency exit — required by building code for any basement or below-grade bedroom. Installing one usually means cutting the foundation, adding a window well, and meeting minimum clear-opening dimensions (generally 5.7 sq ft, with specific width, height, and sill-height rules). Beyond safety and code compliance, an egress window transforms a dark basement into a bright, usable, legal living space — and we handle the permitting and waterproofing that come with it.

Egress Window Installation FAQs
What size does an egress window need to be?
Code generally requires a minimum clear opening of 5.7 square feet, at least 20 inches wide and 24 inches tall, with a sill no more than 44 inches above the floor. We size the window and well to meet the current Georgia code.
Do I need a permit for an egress window?
Yes — cutting a foundation opening requires a permit and inspection in Cobb County. We manage the permit process as part of the installation.
