When the Rain Comes Down
When rain pours off the roof, the water has to go somewhere. If it pools near the foundation, you can end up with soil erosion, moisture issues, or a muddy path at the base of the downspout. That's the core problem: you need a reliable way to move roof runoff away from the house. Two common approaches are flexible downspout extensions that you can angle past obstacles and splash blocks that sit at the downspout's base and spread the water across the ground. These four products cover both routes for roofing gutters waterproofing.
Quick Take
- Need an adjustable path that can stretch beyond a downspout? The expandable flex extension is the flexible option.
- Need to cover several downspouts at once? The Suncast set gives you multiple decorative blocks.
- Want a sloped two-block design? The NAACOO set is built for that.
- Just need a single replacement block? The Suncast replacement guard is a compact, one-unit choice.

Product Notes
2-Pack Expandable Flex Downspout Extension
The flexible downspout extension comes as a 2-pack and can stretch from 21 to 60 inches, which makes it a strong candidate when you need to route water past a sidewalk, flower bed, or narrow walkway. It's made in the United States and comes in white, so it tends to blend into existing gutter systems. Because it is flexible, you can shape it to the space rather than relying on a fixed block. The catch: this is the only pick here that uses an expandable pipe instead of a splash block, so the installation approach is different from the other three.
Suncast Decorative Splash Block, Light Taupe 6-Pack
This Suncast option arrives as a 6-pack of decorative splash blocks in light taupe, which is useful if you have multiple downspouts around the house and want a consistent look. The listed price is the highest in this group, but the per-unit cost spreads across six blocks rather than one or two. Each block is styled to fit at the base of a downspout and help direct runoff away from the foundation. The main limitation is that you're buying a full set of six, so if you only need one or two, you'll have extra pieces to store or place at other downspouts.
NAACOO 24-Inch Sloped Splash Block Pair
The NAACOO pair gives you two 24-inch splash blocks designed with a 15° slope to help water flow away from the house. The dark green finish fits landscaping settings where a neutral gutter block might stand out. The ladder-downward design avoids storing dirt or water, and the UV-resistant PP material resists fading in typical weather. It's a practical middle-ground option between a single block and a six-pack. The limitation: the blocks are fixed at 24 inches, so they can't stretch or adjust to a wider target area like a flexible extension can.
Suncast SBR24 Replacement Guard
The Suncast SBR24 is a single decorative splash block designed as a replacement guard for an existing downspout setup. It's the lowest-priced item in the comparison, which makes it a straightforward choice when you already have the surrounding gutter infrastructure and just need one block at a specific spot. The SBR24 model number makes it easy to match against your current Suncast block. The flip side: it's a single unit rather than a multi-pack, so if you need coverage at more than one downspout, you'd be ordering multiple pieces.
Final Recommendation by Use Case
- If you need an adjustable route that can bend across a gap: the expandable flex extension is the flexible way to go.
- If you have multiple downspouts and want a coordinated look: the Suncast set covers more ground.
- If you want a dark green block setup: the NAACOO blocks balance coverage and price.
- If you only need to replace one splash block: the Suncast replacement guard is the straightforward pick.
Whichever route you choose, the goal is the same: get rainwater safely away from the foundation and let your gutters do their job.
