Can You Waterproof Your Basement On Your Own?

Embarking on DIY projects around the house can be a rewarding experience. However, when it comes to waterproofing your basement, the stakes are high. At Aquatech Waterproofing, with over 25 years of vetted experience in treating wet and leaky basements across Toronto and the GTA, we often get asked by homeowners whether it’s feasible to take on basement waterproofing as a DIY project.

The Short Answer

Yes, and no. Certain aspects of basement waterproofing can be addressed by homeowners who have the right tools and a substantial understanding of the intricacies involved. For minor issues like small leaks or preventative measures, taking the DIY route can be cost-effective. However, for comprehensive protection from water damage, nothing beats professional services.

DIY Waterproofing: Pros and Cons


    – Cost-Saving: Tackling waterproofing yourself can save you money in labor costs.

    – Flexibility: You can work on your own schedule and pace.

    – Direct Control:** DIY gives you manageability over the materials and methods used.


    – Complexity: Waterproofing requires an understanding of your home’s construction and soil conditions.

    – Risk of Errors: Mistakes can lead to more significant problems & higher costs down the line.

    – Physical Demands: Hard labor, excavation, and heavy lifting are often involved.

    – Missing the Expertise: Professionals bring skills and knowledge that aren’t easily replicated.

When To Consider a Professional

Major Leaks or Flooding: If you are experiencing consistent water intrusion, especially after heavy rainfalls, professional waterproofing services may be necessary. 

Foundation Issues: Cracks or weaknesses in the foundation should be handled by experts with the right equipment and know-how.

When To Consider a Professional

High Water Table: If the water table is high in your area, intricate solutions like interior weeping tile systems might be required.

Mold and Mildew: These suggest long-standing moisture problems, often requiring a more technical approach than surface-level remedies.

DIY Waterproofing Methods

If you decide to proceed with DIY waterproofing, here are several methods that can be considered for different scenarios:

Interior Sealants: For condensation and minor dampness, various sealants and waterproofing paints can be applied to your basement walls and floor.

Sump Pump Maintenance: Ensuring your sump pump is in working order can be a proactive approach to handle minor water ingress.

Exterior Downspout Extensions: Diverting water away from the foundation through downspout extenders is a simple yet effective DIY measure.
