4. Clear Out Downspout Clogs Naturally

5. Install Splash Blocks for Water Direction
DIY Concrete or Rubber Solutions
No splash block? Water ends up pooling next to your house—and that’s a big nope.
Make your own splash block using concrete molds or repurposed rubber mats. They redirect water like a pro without breaking the bank.

6. Elevate Sagging Downspouts with Brackets
Finding the Right Support Gear
Over time, downspouts sag, especially if they’re unsupported or full of debris. All you need are a few wall-mount brackets to lift them up and keep them straight.
Visit our downspout gear tag for bracket ideas and support systems.
7. Re-Angle for Proper Drainage Flow
Adjusting Slope Without a Contractor
Improper slope equals standing water. And that leads to—you guessed it—damage. To re-angle:
- Loosen the mount points
- Adjust the slope to at least 1/4 inch per foot
- Retighten and test with water
It’s one of those downspout problems that’s easy to ignore but makes a huge difference.
8. Paint and Protect for Longevity
Choosing Weatherproof Coatings
Paint isn’t just about aesthetics—it’s about protection. Choose a rust-resistant outdoor paint and give your downspouts a fresh coat.
This slows corrosion and makes your home look sharp, too.
Add this to your long-term care checklist from our downspout neglect tag.
When to Call in the Pros
Sometimes DIY won’t cut it. If your repairs aren’t holding or you notice water damage indoors, it’s time to go pro. Use our licensed contractor directory or head straight to Pro Help.
