Downspouts should extend at least 3 to 6 feet away from the exterior foundation of your home. Directing rainwater too close to the foundation allows water to pool, saturate surrounding soil, and seep into basements or crawlspaces. Utilizing downspout extensions, splash blocks, or underground corrugated drainage pipes to push water a minimum of 4 to 6 feet away safely protects your structural foundation and prevents costly water damage and soil erosion.
