Measure existing opening, well depth, grade and drainage without altering structure.
V18 — specialized system
Basement window well and egress
Coordinate opening, window well, drainage, light, clearance, egress and foundation when a basement window becomes a safety component.
Checked: 2026-08-22
A basement bedroom or enlarged opening can trigger egress, structural and permit requirements.
Foundation cutting, unknown lintel, leakage or non-compliant egress: design/verify before work.
Useful tools / data
- Window/well dimensions
- Foundation plan
- Drainage/grade photos
What the professional checks
- Verify egress per jurisdiction
- Design opening/reinforcement
- Coordinate drainage/waterproofing
