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.

NorCal basement egress windows should include a window well cover to prevent rain accumulation during winter storms. Proper drainage below the window well is critical given the Sacramento region's clay-heavy soils.

Livermore is located in Alameda County (East Bay). Wine country and lab town with diverse housing from older ranches to new estates. The local utility provider is PG&E.

Install the egress window with proper flashing and sealant, insulate around the frame, finish interior drywall returns, and install the window well cover if selected.

Inspection & Cleanup

1-2 hrs

Schedule the building inspection to verify egress compliance (opening size, sill height, clear area). Clean up excavated soil, restore landscaping, and demonstrate window operation.

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.
