Egress window installation provides a safe emergency exit from basement bedrooms and below-grade living spaces. The project includes cutting a new opening in the foundation wall or enlarging an existing window opening, installing a window well (for below-grade installations), waterproofing, and fitting a code-compliant window that meets IRC minimum size requirements: 5.7 sq ft of clear opening, minimum 20-inch width, and maximum 44-inch sill height. This is one of the most important safety upgrades for NorCal homes with finished basements.

Egress Window Installation en Larkspur — Preguntas Frecuentes

What size window qualifies as egress?+

Per IRC and California Building Code, an egress window must have a minimum net clear opening of 5.7 sq ft (5.0 sq ft at grade), minimum 20-inch width, minimum 24-inch height, and maximum 44-inch sill height from the floor.

Do I need an egress window in my basement bedroom?+

Yes. California Building Code requires every sleeping room to have at least one egress window or door for emergency escape. Finishing a basement bedroom without an egress window is a code violation and a serious safety risk.

How much does egress window installation cost?+

A complete egress window installation including foundation cutting, window well, and the window itself runs $2,500-$5,500 in the Sacramento area. The cost depends on foundation type, soil conditions, and window well size.

Can I install an egress window myself?+

Egress window installation involves cutting the foundation, which requires specialized tools and structural knowledge. A permit and inspection are mandatory. We strongly recommend professional installation for safety and code compliance.
