The following nine practical tips can help you effectively prevent water from making an unwanted entrance into your basement after a rainstorm:

1. Ensure Proper Landscape Grading

The layout of your property’s landscaping should be designed to encourage rainwater to flow away from your home. The soil should have a positive grade, which means it slopes away from a structure. A negative grade, on the other hand, allows water to pool next to your basement walls and leak inside. 

2. Maintain Gutters and Downspouts

Your gutters and downspouts play a crucial role in directing rainwater away from your home. Regular cleaning and maintenance of these components are vital to prevent water leakage into your basement. In case you’re uncomfortable doing this, hiring a professional for cleaning, repair, and replacement is advisable.

3. Check Exterior Drainage

Drainage pipes are usually placed next to your foundation during construction to prevent water intrusion. If these pipes become crushed or clogged, water can leak into your basement. Similarly, the damp proofing or tar coating on the walls can degrade over time. Regular inspection and maintenance of these aspects can help prevent water leakage.

4. Clean Basement Window Wells 

If your basement has windows and window wells, ensure they’re well-maintained to prevent water seepage. Regular cleaning, sealing, and repair can help. Consider installing covers on your window wells for extra protection.

5. Avoid Waterproof Paints or Sealants

Applying “waterproof” paint or sealant to your basement walls might seem like an easy fix, but it’s temporary. These coatings can flake and bubble, still allowing water to seep through. Therefore, they should not be your primary line of defense.

6. Install a Sump Pump

An effective measure to protect your home’s foundation from excess water is installing a sump pump. Typically situated at the lowest part of your basement or crawl space, this device’s main function is to gather and channel surplus water away from your home.

7. Install a Dehumidifier 

High humidity levels in your basement can lead to condensation, which makes your basement damp, even without any visible leaks. This dampness can create an environment ripe for mold and mildew.

To combat this issue, consider installing a dehumidifier in your basement. These appliances are effective at reducing humidity levels, thereby making your basement less susceptible to dampness and potential mold problems. When selecting a dehumidifier, consider the size of your basement and its current humidity level. Some advanced models can even be integrated into your home’s HVAC system, providing seamless control over the humidity in your basement.

Regularly inspect your basement after heavy rain to spot any signs of water leakage. If you find any moisture, it’s essential to address the issue promptly. Even a small amount of water can lead to problems like mold growth, health issues, damaged belongings, and foundation deterioration. Don’t regard this as a “normal” occurrence but as a serious issue that needs immediate attention.

9. Call the Pros 

Dealing with a leaky basement after heavy rain can be a daunting task, but taking preventative measures can save you from stress and potential damage. Remember, every house and situation is unique, so it’s crucial to identify what works best for your specific scenario. Some methods might offer a quick fix, but for long-term protection and peace of mind, professional solutions are your best bet.
