Simple Downspout Fixes to Keep Your Basement Dry

A flooded basement doesn’t always start with a big storm or a busted pipe. Sometimes, it’s as simple—and preventable—as poor downspout drainage.

At Total Home Water Restoration, we’ve seen dozens of homes in Grove City, Hilliard, and Columbus flooded from nothing more than a clogged or poorly placed downspout. Let’s walk through a few fixes you can tackle today to keep water away from your foundation and out of your basement.

Why Downspout Drainage Matters

When your gutters fill up with rain, the downspout is supposed to guide all that water away from your house. But if it dumps water right at your foundation—or worse, leaks against the house—it can seep down and flood your basement. Water damage here often shows up as:

• Wet basement carpet or drywall

• Musty smells

• Cracking or shifting foundation

• Mold growth

Quick Downspout Fixes You Can Do Today

1. Add Downspout Extensions

The fastest fix? Snap on a plastic or aluminum downspout extension. These are cheap, available at any home store, and can guide water 3–6 feet or more from your foundation.

2. Redirect Water With Drainage Pipe

For a more permanent solution, connect your downspout to a corrugated drain pipe and bury it. Run the pipe to a slope or pop-up emitter at least 6–10 feet from the house. (Make sure it slopes at least 1/8" per foot.)

3. Use Splash Blocks—But Use Them Right

A concrete or plastic splash block helps spread the water out and direct it downhill. Just make sure it’s angled away from the house, not sitting flat or pointing back toward the wall.

4. Check for Clogs

Leaves, sticks, and roof debris can clog elbows and vertical parts of the downspout. Flush each section with a garden hose and use a plumber’s snake if needed.

Common Downspout Mistakes to Avoid

• Too short – Extensions that stop right at the foundation aren’t enough.

• Pointing uphill – Water won’t drain properly if it flows toward the house.

• Disconnected at the base – Make sure elbows and connectors are tight and sealed.

Basement Flooding Still Happening?

If water still makes it into your basement, it’s time for professional help. We can inspect the slope of your yard, foundation cracks, clogged exterior drains, or possible sump pump issues. In some cases, downspouts draining into old clay tiles or failed footing drains may need to be re-routed entirely.

FAQs

Q: How far should downspouts drain away from my house?
A: At least 6 feet is a good start. More if your yard slopes toward the house.

Q: Can I run a downspout into my driveway or sidewalk?
A: It’s not recommended. That water can freeze in winter and cause slipping hazards or damage. Redirect to a lawn or safe runoff area.

Q: What if my downspout drains underground and I don’t know where it goes?
A: You might need a camera inspection or water test to trace it. If it's clogged or collapsed, it could back up water at the foundation.
