How Much Should It Cost to Waterproof a Basement?

Do you have water in your basement, and now you’re exploring ways to waterproof it? That’s a great idea! But we know the biggest thing on your mind—outside of keeping your home safe—is how much basement waterproofing costs

At EverDry Waterproofing of Greater Indiana, we make sure you’re always fully informed about your options and all the costs involved. In this blog, we’ll go over some typical basement waterproofing prices so you can feel confident and prepared about what’s coming next.

How Much Does It Cost to Waterproof a Basement? Key Factors Affecting the Price

Before we can even begin to answer how much basement waterproofing services cost, it’s important to understand that the price can vary depending on several key factors:

  • The size of your basement. Larger basements typically need more materials and labor, which increases overall cost.
  • The condition of your foundation and floor. Issues like cracks, settling, or shifting can make the job more complex and drive up the price.
  • The extent of water damage. A slightly damp basement and one with standing water or flooding call for very different—and differently priced—solutions.
  • Whether foundation repair is needed. Structural fixes such as crack injections or wall reinforcement add to the overall scope and cost of the project.

It’s also important to understand the difference between interior and exterior basement waterproofing. Interior waterproofing methods manage water that gets in, like drainage systems, sump pumps, and vapor barriers. Exterior waterproofing focuses on stopping water before it reaches your basement walls, using solutions like excavation, sealing, and exterior drainage. Basement waterproofing often includes a mix of both, depending on where the water’s coming from.

Average Basement Waterproofing Costs

Now, let’s break down what goes into the cost of basement waterproofing. While no two homes are exactly alike, understanding the main factors can help you get a realistic starting point for your project.

Interior Drainage Systems

This is one of the most common and effective ways to keep your basement dry. An interior drain tile system runs along the inside perimeter of your basement floor to catch groundwater and direct it to a sump pump. It’s installed just below the surface to relieve hydrostatic pressure, meaning the force of groundwater building up around your foundation and pushing its way in. This system keeps that pressure in check and safely moves water out before it causes damage.

  • Ballpark Cost: $2,000–$7,000

Backup Sump Pump Installation

If your current sump pump can’t keep up during heavy storms—or you just want to be proactive—a backup sump pump adds essential peace of mind. Whether it’s a power outage or mechanical failure, a reliable battery-powered unit like the SmartPower™ system keeps water moving and your basement protected. It’s extra defense when you need it most.

  • Ballpark Cost: $1,200–$3,000

Exterior Excavation and Waterproofing

This is the heavy-duty option. Exterior waterproofing requires excavating and digging around your foundation to install a protective barrier. We apply waterproof membranes, drainage boards, or gravel systems designed to stop moisture from seeping through your foundation walls. This method is ideal for homes with serious moisture problems, high water tables, or constant exterior pressure from saturated soil.

  • Ballpark Cost: $8,000–$15,000+

Foundation Crack Repair

Cracks in your basement walls or concrete floor can become water entry points. Depending on the size and severity, they can be filled and sealed using polyurethane foam, epoxy, or carbon fiber to help prevent water damage. Minor issues might cost less, but deeper or spreading cracks with water seeping in need more involved repairs.

  • Ballpark Cost: $250–$800 

Foundation Wall Stabilization

If your basement walls are bowing, cracking, or shifting, that’s a sign of structural stress, and waterproofing alone won’t solve it. The first step is to stabilize the wall and stop movement. One highly effective solution is the Stabl-Wall™ system. It uses ultra-thin carbon fiber sheets that bond directly to your concrete walls, adding strength without taking up space.

  • Ballpark Cost: $2,000–$10,000+

Waterproof Coatings and Vapor Barriers

Interior waterproof coatings help block water seepage from coming through porous concrete walls, while vapor barriers reduce humidity and prevent musty air. On their own, they’re not enough to stop leaks, but they work well when paired with drainage systems to keep your basement dry and your air cleaner.

  • Ballpark Cost: $1,000–$4,000

French Drains and Surface Water Control

French drains installed along the outside of your house help redirect excess water. These systems often go hand-in-hand with gutter improvements, extending downspouts, grading corrections, and other exterior fixes to stop rainwater from accumulating around your foundation.

  • Ballpark Cost: $2,000–$6,000

So what’s the total price of basement waterproofing? You’re probably looking at anywhere between $1,200 and $15,000+ depending on the size of your basement, severity of the issue, and the solutions required. But before you start panicking, know that we can’t give you an exact number without seeing your space first—and that’s why we offer a free inspection.

Why DIY Basement Waterproofing Is a Bad Investment

Trying to tackle basement leaks on your own might sound like a money-saver, but do-it-yourself basement waterproofing often creates more problems than it solves.

Quick fixes like hardware store sealants or patch kits might seem convenient, but they lack the durability to hold up long-term and won’t stop water at the source. Without the right tools or experience, it’s easy to overlook serious moisture issues—like poor drainage, shifting soil, or hidden foundation damage—that can lead to bigger problems.

In the end, it’s not a long-term solution, and you’ll likely spend more fixing what DIY couldn’t. Plus, you won’t have any warranty protection. That’s why professional experience (and who you hire) matters.
