Understanding Basement Leaks: Causes and Risks
Before diving into repair strategies, it’s essential to understand what causes basement leaks and why addressing them quickly is so important.
Common Causes of Basement Leaks
Basement leaks occur for various reasons, most commonly due to:

- Cracks and Gaps: Small cracks in foundation walls or floors that widen over time.
- Poor Drainage: Improper grading or clogged gutters divert water toward the foundation.
- Plumbing Issues: Leaky pipes or appliances inside the basement.
- Window Wells: Improperly sealed window wells allow water intrusion.
Risks and Consequences of Ignoring Basement Leaks
Ignoring basement leaks can lead to:
- Structural damage and foundation weakening.
- Mould growth is impacting indoor air quality.
- Increased humidity is damaging belongings and finishes.
- Pest infestations are attracted to damp environments.
- Decreased property value.
