Basement flooding after heavy rain isn’t just inconvenient—it’s a sign of an underlying plumbing or drainage issue. In Dayton and surrounding areas, we often see a surge in calls after big storms. If you’re wondering why this keeps happening and how to stop it, here’s what you need to know.
Common Reasons Basements Flood After Storms
1. Clogged or Overwhelmed Floor Drains
Most homes have a basement floor drain that connects to the main sewer line. If your drain is clogged or your sewer is backing up, water has nowhere to go—and ends up on your basement floor.
See our guide on what to do when your basement backs up for more info.
2. Broken or Bellied Sewer Line
Heavy rain increases groundwater pressure. If your sewer line is cracked, collapsed, or sagging, it can’t handle the inflow, leading to backups and indoor flooding.
A video pipe inspection can identify these issues fast.
3. Poor Foundation Drainage
Older homes often lack modern foundation drainage systems. Water seeps into walls, floors, or cracks, especially if downspouts are too close to the house or the yard slopes inward.
4. Sump Pump Failure
If you have a sump pump and it fails—or can’t keep up with water volume—your basement becomes a reservoir. Always test your sump pump before storm season and consider installing a battery backup system.
5. Tree Root Intrusion
Roots can invade your pipes through small cracks and create blockages. When stormwater surges, the clogged lines cause water to back up into your basement.
How to Fix and Prevent Basement Flooding
Clear debris from gutters and downspouts- Extend downspouts at least 6 feet from the foundation
- Install or service your sump pump
- Use hydrojetting to clear major blockages
- Repair or replace damaged sewer lines
- Add backwater valves to prevent city sewer water from backing into your home
