We will also reference expert advice from trusted sources like Family Handyman and This Old House to ensure that you receive accurate and helpful information. Discover how proper basement waterproofing can significantly improve your home’s overall quality and longevity.

1. Inspect and Maintain Your Gutters and Downspouts

Overflowing gutters and improperly installed downspouts can lead to water seeping into basements. Ensure your gutters are clean and free of debris to prevent water from overflowing and pooling around your foundation. Downspouts should direct water at least 5-6 feet away from your home’s foundation (Family Handyman). Regularly inspect and maintain your gutters and downspouts to prevent water damage in your basement.

2. Grade the Soil Around Your Home

Proper soil grading is essential for preventing water from pooling around your foundation and seeping into your basement. The soil around your home should slope away from your foundation, with a drop of at least 6 inches within the first 10 feet (This Old House). By ensuring proper grading, you can help direct water away from your home and keep your basement dry.

3. Install a Sump Pump

A sump pump is a valuable tool for keeping water out of your basement. It collects water in a pit and pumps it away from your home’s foundation. Consider installing a sump pump to help keep your basement dry and prevent flooding. Regularly inspect and maintain your sump pump to ensure it is functioning correctly and efficiently.

4. Seal Cracks and Holes in Walls and Floors

Cracks and holes in your basement walls and floors can allow water to seep into your basement. Inspect your walls and floors for any cracks or holes and use a high-quality, waterproof sealant to fill them. For larger cracks or structural concerns, consult with a professional for expert advice and repair services.

5. Apply a Waterproof Coating to Walls and Floors

A waterproof coating can provide an additional layer of protection against water seeping into your basement. These coatings are designed to create a barrier between your basement walls and floors and any moisture trying to enter. Consider applying a waterproof coating, such as a concrete sealer or waterproof paint, to help keep your basement dry. Be sure to follow the manufacturer’s instructions for proper application and maintenance.

6. Install a Vapor Barrier

A vapor barrier is a material that prevents moisture from entering your basement through the walls and floors. By installing a vapor barrier, you can help reduce the amount of moisture entering your basement and prevent the growth of mold and mildew. Vapor barriers are typically made from plastic sheeting or foil and can be installed on the interior or exterior of your basement walls and floors. For more information on vapor barriers and professional installation, consult a reputable waterproofing expert.

7. Insulate Your Basement Properly

Proper insulation is essential for maintaining a dry and comfortable basement environment. Insulation can help regulate the temperature in your basement, preventing condensation and reducing the risk of mold and mildew growth. When insulating your basement, it is crucial to use the appropriate materials and techniques to prevent moisture from becoming trapped between the insulation and the walls or floors. According to Energy.gov,using rigid foam insulation on the interior or exterior of your foundation walls can be an effective method for insulating basements while minimizing moisture issues.


Keeping your basement dry and well-maintained is crucial for your home’s overall health and structural integrity. By following these seven waterproofing tips, you can prevent water damage, mold, and mildew growth, and ensure that your basement remains a safe and comfortable living space. Regular inspections and maintenance of your gutters, downspouts, sump pump, and foundation, combined with proper grading, sealing, insulation, and vapor barriers, can significantly improve your basement’s waterproofing and help you avoid costly repairs in the long run.
