Real Stories, Real Protection

Pump Failures Create Real Costs
Insurance May Not Cover

Structural Issues

When a sump pump stops working, water pressure can build quickly around your home’s foundation, leading to cracks, shifting, and long-term structural issues. Unfortunately, damage caused by groundwater intrusion or gradual seepage is often excluded from standard insurance coverage.

Property Damage

Sump pump malfunctions can allow water to spread across your basement floor, damaging furniture, appliances, and irreplaceable personal items. Even when contents are covered, basement limits, depreciation, and exclusions often leave homeowners paying far more out of pocket than they’d expect.

Mold Growth

Moisture left behind after a pump failure creates the ideal conditions for mold growth inside your walls, floors, and fixtures. Mold damage is frequently excluded or tightly capped by insurance policies, especially when it develops after the initial flooding event and cleanup is delayed.

Proactive Sump Pump Testing vs. Reactive Sump Pump Monitoring

Not all sump pump systems protect your home the same way. The difference comes down to whether problems are found before an emergency — or during one.

Proactive Testing

Reactive Monitoring

Daily Testing

Basement Defender is the only system that physically tests both your primary sump pump and DC backup every day to identify problems before an emergency occurs.

Complete Coverage

This system monitors sump pump performance, humidity, and temperature to help identify conditions that increase the risk of basement flooding or water damage.

Manual Testing

You can easily run sump pump tests anytime you’d like through a free mobile app to confirm system performance, readiness, and ensure proper operation.

Proactive Alerts

You’ll receive real-time notifications whenever an issue is detected, giving you the time needed to respond and take action before flooding or water damage occurs.

Continuous Monitoring

The system automatically tracks your sump pump’s activity around the clock to detect unusual behavior, performance changes, and potential problems early.

Proven Protection

Basement Defender provides reliable protection against basement flooding caused by sump pump failure, power issues, or undetected system problems.

Easy Installation

Set up your Basement Defender Wi-Fi sump pump alarm in minutes using clear, step-by-step instructions designed for homeowners.

Easy Connection
