In Southeastern Wisconsin, our basements are more than just storage, they are extensions of our homes. However, with the heavy spring thaws and summer downpours common in Burlington, a flooded basement is a risk every resident must take seriously. Water damage can lead to structural rot, ruined memories, and hazardous mold growth within just 24 hours.

At PuroClean of Burlington, we believe the best restoration is the one that never has to happen. Our professional staff has identified the five most effective ways to keep your basement dry, even when the Wisconsin weather is at its worst.
What is the most common cause of basement flooding?
The most common cause of a flooded basement in Burlington is sump pump failure, often due to power outages or mechanical wear during heavy storms. Other major contributors include clogged gutters that dump water directly at the foundation and poor yard grading that allows surface water to pool against basement walls. Regular maintenance of these systems is the first line of defense against water damage.
1. Maintain and Backup Your Sump Pump
Your sump pump is the heart of your basement’s flood defense. In Burlington, where storms can often knock out power, a standard pump isn’t enough.
- Test Regularly: Pour a bucket of water into the pit to ensure the float switch triggers the pump.
- Install a Battery Backup: Most flooded basement incidents happen during power outages. A battery-powered backup ensures your pump keeps running when the lights go out.
- Listen for Noises: If your pump is making grinding sounds, it may be time for a professional replacement.
2. Clean Your Gutters and Extend Downspouts
If your gutters are overflowing, they are dumping hundreds of gallons of water right next to your foundation.
- Clear Debris: Clean your gutters at least twice a year to prevent clogs.
- The 5-Foot Rule: Ensure your downspouts extend at least 5 to 10 feet away from your home’s foundation. This prevents water from “recycling” back into your basement through the soil.
3. Inspect the Grading Around Your Home
The ground around your foundation should always slope away from the house. Over time, soil settles, which can create a “bowl” effect that traps water.
- Check the Slope: Ensure the ground drops at least one inch for every foot of distance away from the foundation.
- Fill Low Spots: Use heavy clay soil to fill in areas where water pools near the basement walls.
4. Seal Foundation Cracks
Even a tiny hairline crack can let in a significant amount of water under hydrostatic pressure.
- Internal Inspection: Check your basement walls for damp spots or white, powdery residue (efflorescence), which indicates water is seeping through.
- Professional Sealing: For larger cracks, consult a licensed professional to use epoxy or polyurethane injections to seal the leak from the inside out.
5. Install a Water Leak Detection System
Technology is your best friend when it comes to preventing a flooded basement.
- Smart Sensors: Place small water sensors near the water heater, sump pump, and washing machine.
- Instant Alerts: These devices connect to your smartphone and will alert you the second moisture is detected, allowing you to call for Emergency Water Damage Repair before the water rises.
Frequently Asked Questions (FAQs)
Q: Does homeowners insurance cover a flooded basement? A: Standard policies often do not cover “sewer backup” or “overland flooding” unless you have a specific rider. Check with your local Burlington agent to ensure you are covered for sump pump failure.
Q: Can mold grow after a basement flood? A: Yes, mold begins to grow within 24–48 hours of water exposure. This is why immediate extraction and drying by a certified team are critical.
Q: How do I know if my sump pump is too old? A: Most sump pumps have a lifespan of 7 to 10 years. If yours is approaching a decade of service, consider replacing it before the next big storm.
Conclusion: Stay Proactive, Stay Dry
In summary, preventing a flooded basement requires a mix of mechanical maintenance and smart landscaping. By following these five steps, you can significantly reduce your risk of water damage.
