Common Symptoms
Cracked, shattered, or missing glass in a basement window
Water intrusion through the broken window during rain or from window well drainage
Cold air drafts entering the basement through the damaged window
Insects, pests, or rodents entering through the opening
Musty smell or visible mold growth around the damaged basement window frame
What Causes This
Impact from lawn equipment, debris ejected by mowers or trimmers near the window well
Hydrostatic pressure from water-saturated soil pushing against the window during heavy DMV rainstorms
Foundation settling causing the window frame to distort and stress the glass
Window well flooding during heavy rain overwhelming the drain and pressing water against the glass
Age-related failure of old single-pane glass or deteriorated wooden frames in older DMV homes
How to Fix It
Solution Steps
1Cover the opening immediately with plywood or heavy plastic sheeting to prevent water entry, pest intrusion, and security breach
2Clear the window well of debris and ensure the drain is functioning to prevent water buildup against the temporary cover
3Assess the window frame condition — if the frame is rotted or distorted, frame repair may be needed before glass installation
4Contact Virginia Glass Windows for measurement and replacement — basement windows require specific sizing and may need to meet egress code requirements
5A technician will install new glass (or a complete window unit if the frame is failed) and verify weatherseal integrity
When to Call a Professional
Immediately for security — a broken basement window provides easy concealed entry to your home
When water is actively entering through the opening during rain events
When the window is an egress window (bedroom basement) and must meet code requirements for size and operation
When the frame is rotted, rusted, or distorted and cannot hold new glass properly
Stay Ahead
Prevention Tips
Install window well covers to protect basement windows from debris, water, and snow accumulation
Keep window wells clear of leaves and debris to ensure proper drainage
Direct lawn equipment discharge away from basement window wells
Inspect basement window frames and glazing annually for deterioration, especially in older DMV homes with wood frames
Ensure window well drains are connected and functional to prevent hydrostatic pressure against the glass
Common Questions
FAQs About This Problem
An egress window is a code-required emergency exit window in any basement room used as a sleeping area. The International Residential Code requires a minimum opening of 5.7 square feet with specific height and width minimums. If your broken basement window is in a bedroom, the replacement must meet egress requirements.
