Buying Guide

Choose the right type

Decide between extensions that lengthen the downspout outlet and splash blocks that diffuse flow; extensions route water farther while splash blocks reduce erosion near the foundation

Match material to climate

Rubber splash blocks resist cracking and weathering in freeze–thaw conditions, while rigid extensions may suit milder climates where long-term shape retention matters

Check compatibility and sizing

Confirm the downspout extension or splash block fits your existing downspout profile and outlet dimensions to avoid leaks or poor alignment

Prioritize water-management performance

Look for features that direct water away from the foundation—angled outlets, extendable sections, or textured bases that slow and disperse flow

Consider durability and maintenance

Weather-resistant materials and simple, tool-free installation reduce long-term upkeep; rubber products often provide impact resistance and easy positioning
