DIY Basement Waterproofing Tips

Reasons for DIY Basement Waterproofing

Before embarking on a DIY basement waterproofing journey, it’s essential to understand the potential advantages and disadvantages.


DIY basement waterproofing comes with many benefits, primarily:

  • Cost Savings: By taking on the project yourself, you can avoid the expenses of hiring a professional contractor, which can be anywhere from $16 to $20 an hour.
  • Flexibility and Convenience: DIY waterproofing lets you work on your own schedule at your own pace. This flexibility lets you prioritize specific areas, tailor the whole process to your needs, and even complete the project in phases if you’d like.
  • Complete Control: Doing it yourself means you have absolute control over the project, allowing you to choose materials, techniques, and products that fit your budget and personal preferences. This level of customization gives you a more personalized solution.


On the flip side, DIY waterproofing does have its cons:

  • Time and Effort: While it’s certainly doable, basement waterproofing is a labor-intensive project that requires preparation, attention to detail, and patience. It can be time-consuming, particularly if you have limited experience with home improvement projects.
  • Potential Errors: Without an expert, there’s the risk of making mistakes that could compromise the effectiveness of waterproofing. A poor waterproofing job can lead to leaks and other issues.
  • Limited Warranty: The most crucial disadvantage of DIY basement waterproofing is that you won’t have the warranty coverage provided by professional waterproofing companies. If an issue arises, you’ll be responsible for addressing them without support.

DIY Basement Waterproofing Tips

If you choose the DIY route for waterproofing your basement, you must remember these steps to ensure everything goes smoothly.

Seal Any Cracks

Take the time to identify and seal all cracks in the basement walls and floor. Thoroughly clean the surface, apply the sealant, and allow it to dry according to the manufacturer’s instructions. If you are DIY waterproofing, ensure you use a high-quality sealant.

Make Sure the Gutters are Clear

Clogged gutters can lead to water overflow, which could flood your basement. Regularly clean and maintain your gutters to ensure proper water drainage. Keep them clear of leaves, twigs, and debris. You may want to install gutter guards to minimize debris accumulation.

Install a Sump Pump

A sump pump is key for removing excess water from your basement. Locate the lowest point in your basement and install a sump pump to collect and discharge water away from your home. Choose a model suitable for your basement size and install it according to the manufacturer’s guidelines. Pro Tip: This is a step you can do later.

Install a Vapor Barrier

A vapor barrier helps prevent moisture from seeping through the walls. Install a high-quality vapor barrier on the walls and floors, ensuring complete coverage and proper sealing.

Best Practices and Considerations for DIY Basement Waterproofers

It doesn’t end there once you’ve completed your DIY waterproofing project. To maintain a dry and healthy basement environment, there are ongoing practices and considerations to keep in mind:

  • Before starting the project, research and educate yourself about basement waterproofing techniques, materials, and local building codes.
  • Take necessary safety precautions, including wearing protective gear and following proper handling procedures for chemicals and tools.
  • Plan the project carefully, considering the needs of our basement and addressing underlying issues before starting the waterproofing process.
  • Maintain proper ventilation during and after waterproofing to promote a dry environment and prevent moisture buildup.
  • Monitor the effectiveness of the waterproofing over time and be prepared to promptly address any maintenance or repairs.
  • Maintain your gutters regularly and extend downspouts to direct water away from your house.
  • Choose quality materials for all your DIY projects to ensure durability and effectiveness.

DIY basement waterproofing can be a cost-effective option for homeowners who can not afford to hire a contractor and are willing to invest time and effort. Following these tips and best practices, you can protect your basement from water damage, ensuring a dry and comfortable living space for years.

Lastly, remember hiring a professional is okay if the task seems too daunting. A well-executed professional job can offer peace of mind and save you money in the long run if DIY projects result in mistakes.


What are some common mistakes to avoid when doing DIY basement waterproofing?

The most common mistake is ignoring small leaks or cracks, which can become significant problems. Skipping the exterior waterproofing could also lead to water seeping into your basement from the outside. And not installing a drainage system can result in unwanted water accumulation. Finally, not performing regular maintenance checks may let some issues go unnoticed until they become costly repairs.

How long does it take to complete a DIY basement waterproofing project?

Usually, a DIY basement waterproofing project takes a weekend or two. If you install a sump pump or exterior waterproofing, it might take a couple of weeks. However, the duration of a DIY basement waterproofing project largely depends on the basement’s condition and size and the methods you use.

What are some signs that the waterproofing may not be effective?

Signs your basement waterproofing may not be effective include recurring damp spots on walls or floors, mold or mildew, a musty smell, visible cracks, and standing water. If you notice any of these signs, immediately identify and resolve the issue by doing repairs yourself or hiring a professional.
