How Much Does It Cost To Waterproof A Basement?

Are you facing problems with your basement and want to do something to stop water from seeping into your home? If yes, then it’s finally time to start waterproofing your basement. If you’re a homeowner considering this option for your basement, you’re likely wondering how much it will cost, which is what we’ll cover today! 

In this blog post, we’ll provide an overview of the different factors that impact the cost of basement waterproofing and break down the average cost for different types of waterproofing projects. Whether you’re a DIY enthusiast or planning to hire a professional contractor, this guide will help you understand the cost of basement waterproofing and help you make an informed decision.

Average Cost To Waterproof A Basement  

According to industry experts, the national average cost of basement waterproofing ranges from $2,300 to $8,000. However, this is just a general estimate, and the actual cost can be higher or lower depending on the type of basement you have, its size, and the products you use for waterproofing. 

Factors Affecting How Much It Costs To Waterproof A Basement 

In the section above, we provided an estimate of how much this home improvement project could cost you. But as we know, each home is different, and therefore the cost you’ll incur will also not be the same. 

Understanding the different factors that affect the cost is essential in estimating the cost of your project and choosing the best waterproofing method to fit your budget and needs. Here are some of the primary factors that affect the cost of basement waterproofing:

Size Of The Basement 

The size of your basement is a crucial factor to consider when estimating the cost of waterproofing. As we’ve discussed, Tulsa homes come in many different styles, and the size of these basements are also different. 

A larger basement will require more materials and labor to cover the area, increasing the project’s overall cost. Like a roofing system and other home exterior projects, the waterproofing cost is calculated based on a basement’s square footage. For instance, a small basement of around 500 square feet may cost $2,000 to $4,000 to waterproof, while a larger basement of 1,500 square feet or more may cost between $8,000 to $10,000. However, these are rough estimates, and the final waterproofing cost will vary based on other factors, which we will cover next.

Type Of Service

The cost you will pay will vary depending on which type of service you want from your home. When it comes to keeping your basement safe from moisture damage or pooling water, you will be faced with two options: Waterproofing and dampproofing. 

Waterproofing is a comprehensive solution that provides complete protection against water damage. Waterproofing involves several processes that focus on both your home’s interior and exterior. The jobs include applying a waterproof coat, installing drainage systems, and more. These are usually more costly but can help you in the long run.  

On the other hand, the scope of dampproofing is much smaller. It is a simpler and less expensive solution but only provides basic protection against moisture. Dampproofing techniques can protect your concrete foundation from getting damaged due to moisture from the soil. 

Location Factors

The location of your property is another crucial factor that can impact the cost of waterproofing your basement. The cost of labor and materials varies significantly from one area to another, which affects the overall cost of the project.

For instance, if you live in an area where the cost of living is high, you can expect to pay more for waterproofing services. This is because the cost of labor is typically higher in these areas. You should also expect the cost to be higher if you live in a flood-prone area. 

Materials also vary in cost depending on location. Certain materials may be more readily available in some areas, while they may be scarce or expensive in others. 

Pay Attention To The Building Cost 

In addition to the cost of labor and materials, local regulations and building codes also affect the cost of waterproofing. Some areas may have stricter regulations that require more extensive waterproofing measures, which will increase the cost of waterproofing a home. 

Type Of Waterproofing 

You can categorize basement waterproofing methods into two broad categories: Interior and exterior waterproofing, and each method has a different cost. 

For example, exterior waterproofing involves treating the exterior of a home, including the foundation, and grading the soil, which may be costly. You can expect to pay around $8,000 to $12,000. On the other hand, interior waterproofing methods like installing interior drainage systems, and applying paint or a waterproof coating is typically less expensive. 

Exterior Methods

  • Landscape Grading
  • Gutter Installation 
  • Downspout Installation

Interior Methods

  • Sump Pump Installation
  • Drainage System (French Drain) Installation 
  • Epoxy Injection

Type Of Sealant

Sealing a home is an essential component of waterproofing that can be done to the basement’s interior and exterior. The process of sealing involves applying a waterproof membrane or coating to the walls and floors of the basement to prevent water from seeping through cracks. It’s essential to consult with a professional waterproofing contractor to determine the best sealing method for your basement. 

Here’s a breakdown of the type of sealing services offered for the interior and exterior of a home: 


Waterproof coatings are commonly used for basement waterproofing. These coatings are typically applied to the interior or exterior walls of the basement to prevent water from penetrating the foundation walls.


One of the most affordable ways to prevent moisture and water seepage in a basement is by applying paint. It will cost you around $25 to $35 per gallon, as this is special paint made for the purpose of waterproofing. This paint can be applied to the basement’s interior walls to create a barrier against moisture. This method is commonly used for minor water intrusions, such as condensation on the walls, or minor leaks.

Vapor barrier

A vapor barrier is another method used for basement waterproofing. It involves the installation of a thin plastic material in the form of sheets that are placed over the walls and floors of a basement. The vapor barrier helps to prevent moisture and water vapor from penetrating the walls and floors.

Age Of Your Property

The age of your home can also play a significant role in the cost of waterproofing your basement. Older homes may require more extensive waterproofing due to outdated building materials and construction techniques that are less effective in preventing water intrusion. Additionally, older homes may have more wear and tear on the foundation, which can make them more vulnerable to water damage.

Additional Work Needed

Additional work may be required in your basement beyond waterproofing, which can impact the overall waterproofing cost. For example, mold or mildew is a common problem in basements with water intrusion and can have serious health implications if left untreated. If mold is present, it will need to be removed, and the source of the moisture addressed in order to prevent future growth.

The cost of these additional repairs will depend on the severity of the problem and the extent of the work required. It’s essential to work with a professional contractor who can assess the condition of your basement and provide you with an estimate to budget for.
