Taking the decision to waterproof your basement often comes with many questions: Is it necessary? Will it protect my property in the long term? Will it make a difference? We understand that your home is one of your most important investments. Here, we are going to break down the reasons why we highly recommend waterproofing your basement to protect both your safety and your home’s value.
What is basement waterproofing?
Basement waterproofing is the process where you apply a membrane that works as a barrier to prevent water from infiltrating in your foundation, walls, and floor. It protects your home’s structural integrity.
How important is waterproofing?
During rainstorms, water can flow through the soil that surrounds your property, and the increased water pressure can seep through your foundation, walls and footing. It will lead to structural damage, mold growth, damp spots, and cracks.
If water leaks reach your utilities, for example, your HVAC systems, it could carry mold spores through the AC, or water get in contact with electrical sources, creating a serious risk.
Waterproofing will provide you with a protective barrier that shields your property from heavy rainstorms and all these potential risks. It directs water away, preventing it from seeping and penetrating your home. You won’t have to worry about waking up to a wet basement.
Basement waterproofing not only saves you from costly repairs, but it also keeps your building’s structure in good condition, and can increase its value.

Types of Waterproofing Methods
Interior Waterproofing
This method involves installing a drainage system inside your basement to redirect water away from the walls and floor. The process include:
- Site preparation.
- Drainage System Installation.
- Sump Pump Installation.
- Vapor Barrier.
- Sealing joints.
- Water testing.
- Clean up.
Interior basement waterproofing is less expensive than exterior waterproofing and has a shorter installation timeline. However, it does not address the root cause of the problem and only works after water has already entered your basement.
Exterior Waterproofing
It involves excavating around the foundation to apply a waterproof membrane in the exterior wall. The process includes:
- Site preparation.
- Excavation.
- Wall cleaning.
- Crack inspection.
- Crack repairs.
- Waterproofing Membrane Application.
- Drainage System Installation.
- Backfilling.
- Clean up.
Exterior basement waterproofing prevents water from reaching the basement by addressing the root cause of water infiltration and providing a permanent solution. However, it is more expensive than interior waterproofing due to special equipment and a longer installation process.

How many days does it take to waterproof a basement?
It would depend on the square feets, the waterproofing method that will be apply, and if there is water infiltration. On average, when installing drainage systems, we have spent between 1 and 3 business days. When doing exterior waterproofing, where we need to excavate, it could take between 4 days and more than a week, all depending on the extent of the project which we are working on.
What are the benefits of waterproofing?
One of the most important benefits of waterproofing is that it protects your property’s structure from water damage. When the water flows through the ground during heavy rains, it creates pressure that can try to enter your basement. Waterproofing prevents this, keeping your home safe and dry. Other advantages include:
- Energy efficiency: it helps to maintain stable temperature and humidity levels.
- Long lasting protection: it can last up to 10 years.
- Long-term cost savings: you avoid the costly repairs that come after water infiltration.
- Low maintenance: once waterproofing is installed, it requires minimal maintenance.
- Improve your property value: a waterproofed basement is a highly valued asset. Many potential buyers think about the multiple uses they can give to a basement in good conditions.
- Protects Health: It does not just protect your property; it also helps protect your family’s health by preventing mold growth and damp conditions.
Frequently Asked Questions about Waterproofing
Why is my basement wet?
There could be several reasons why your basement is wet. Your sump pump might not be functioning properly, allowing water to collect near your foundation and seep into your basement. Cracks in the foundation could also be letting water in. We recommend reaching out to us for an on-site inspection to identify the exact cause.
Can you finish a basement without waterproofing?
While it is possible to finish a basement without waterproofing, it can lead to serious risks, including water damage, mold growth, damp spots, health concerns, and decreased property value.
Does homeowners insurance cover basement waterproofing?
Homeowners insurance does not cover the cost of basement waterproofing because this is a preventative measure. However, it may help cover specific losses related to basement water damage, but only if the damage is caused by a covered event.
How much will basement waterproofing cost?
The cost of basement waterproofing depends on the size of the project, and the type of waterproofing method used. Prices typically range from $1,500 to $40,000 (or more). Request a free estimate today to get an accurate quote!
What type of basement waterproofing is best?
It depends on your specific situation. For example, if you have a minor water seepage, interior waterproofing is often the best solution. For severe water infiltration or frequent flooding, exterior waterproofing is recommended to address the root cause of the issue.
