In home inspection, water intrusion refers to the unintended entry of water into a building’s structure, which can lead to damage, mold growth, and structural issues. It can occur through various pathways, including:
- Roof leaks (damaged shingles, flashing failures)
- Foundation leaks (poor drainage, cracks in foundation walls)
- Window and door leaks (improper sealing, failed caulking)
- Plumbing leaks (burst pipes, leaking fixtures)
- Basement and crawl space moisture (hydrostatic pressure, poor grading)
- Condensation issues (high humidity, poor ventilation)
Home inspectors look for signs of water intrusion such as stains, musty odors, peeling paint, soft drywall, and visible mold. Addressing water intrusion early helps prevent costly repairs and health hazards.
