A splash block is placed below a downspout outlet to help guide water away from the home. It is a simple part, but it can make a meaningful difference when drainage is otherwise dumping too close to the foundation.
Why It Matters
Roof runoff can add up quickly. If downspout water discharges too close to the home, it may contribute to soil erosion, foundation moisture, mulch washout, or staining.
Common Problems
Common issues include missing splash blocks, splash blocks facing the wrong direction, blocks sitting on settled soil, and short drainage paths that still leave water too close to the house.
Building Codes & Industry Standards
Drainage expectations depend on property conditions and local requirements. Homeowners should focus on whether the system moves water safely away from vulnerable areas.
Exterior Echelon Notes
Exterior Echelon looks at splash blocks and extensions as part of the overall gutter drainage path, not just as accessories at the end of the downspout.
