Wondering how much basement waterproofing costs in Westmont IL? Learn what affects pricing, explore interior and exterior options, and get tips to protect your home from water damage.
If you’re a homeowner in Westmont, IL, and have noticed musty odors, water stains, or damp basement walls, you’re not alone. The area’s heavy clay soil and unpredictable weather make basements especially vulnerable to water damage. Basement waterproofing is an essential investment—but many homeowners aren’t sure what to expect in terms of pricing.
This guide breaks down the cost factors, average price ranges, and options available to help you make an informed decision and protect your home for the long term.
The bigger the problem, the more it will cost to fix. A small leak or moisture issue may require a simple interior drain or crack repair, while widespread water intrusion could call for full excavation and exterior membrane application.
Interior and exterior systems differ in complexity and cost. Interior waterproofing tends to be more budget-friendly, while exterior solutions are more extensive and labor-intensive.
Homes in Westmont vary widely in age. Older homes with cinderblock foundations may require more preparation, while poured concrete foundations typically offer easier access for repairs. The condition and accessibility of your basement can directly influence labor costs.
The size of your basement matters. Larger basements mean more materials, more time, and higher labor costs—especially if you’re installing perimeter drainage systems or wall membranes.
Westmont’s clay-rich soil holds moisture, which increases hydrostatic pressure on foundation walls. If the ground is especially dense, excavation costs for exterior systems may rise. Similarly, poor yard drainage or tight access points around your home can increase labor time and complexity.
If your home needs a new sump pump or a battery backup system, this will be factored into the overall waterproofing cost. Pumps are vital for moving collected water away from your home and preventing flooding.
Basement waterproofing costs in Westmont can vary depending on the severity of the issue, the size of your basement, and the type of system installed. Below is an overview of what homeowners can expect when considering either interior or exterior solutions.
Interior waterproofing systems are generally more affordable and less disruptive since all work is done inside the basement. These solutions are best for controlling water after it enters and are often ideal for homes dealing with seepage or minor leaks.
Common interior waterproofing services include:
Exterior waterproofing is more comprehensive and involves excavating around the home’s foundation. While this method tends to cost more, it’s one of the most effective ways to block water from ever reaching the basement walls.
Typical exterior waterproofing services include:
While exterior waterproofing is a bigger investment upfront, many homeowners choose it for its long-term protection and ability to prevent structural damage caused by hydrostatic pressure and saturated soil.
While core waterproofing solutions make up most of the cost, several additional services can raise the final total. Some of the most common include:
Though optional, these upgrades often help maintain long-term basement health and can be worth the investment, especially in moisture-prone areas like Westmont.
