Wondering if you should seal your concrete basement floor in Westmont, IL? Learn the benefits, when it’s worth it, and how sealing helps prevent moisture and damage.
Concrete is strong and durable, but it’s also porous. Over time, moisture, stains, and surface wear can break down even a solid concrete basement floor—especially in areas like Westmont, where clay-heavy soil and humidity increase the risk of water intrusion.
If you’re finishing your basement, experiencing dampness, or just looking to extend the life of your floor, sealing it might be one of the smartest home improvement decisions you make.
But is it necessary for every homeowner? Let’s take a closer look at when and why you should consider sealing your concrete basement floor in Westmont.
In most Westmont homes, the basement floor is made of poured concrete. While it looks solid, it naturally contains tiny pores and capillaries that absorb water vapor from the ground below.
Left untreated, this can lead to musty odors, mold, discoloration, and even deterioration of the slab over time.
Sealing your concrete basement floor doesn’t just protect the surface—it protects the health and comfort of your entire basement.
A sealed floor acts as a barrier that blocks moisture from rising through the slab. This is especially valuable in Westmont homes where damp basements are common.
Reducing moisture lowers the risk of mold and mildew, which thrive in humid environments. Sealing your floor can help create a cleaner, drier basement space.
If your basement is used for storage, laundry, or as a living area, spills and stains are inevitable. A sealed surface resists oil, paint, rust, and other common household contaminants.
Sealers protect concrete from abrasion, surface wear, and chemical breakdown—extending the life of the slab and making it easier to maintain.
Sealing can give your floor a finished look, whether matte or glossy. It’s also a solid foundation for paint, epoxy coatings, or finished flooring materials like carpet or vinyl.
While every home is different, here are a few signs that sealing may be a smart investment:
In older Westmont homes that were built without moisture barriers under the slab, sealing can make a noticeable difference in comfort and usability.
There are two main types of sealers commonly used for concrete basement floors:
These soak into the pores of the concrete and chemically react to block moisture. They don’t change the look of the floor and are great for long-term protection.

These create a surface coating on top of the slab. They can be glossy or matte and may add color or decorative effects.

No—sealing is a protective measure, not a substitute for full basement waterproofing. If you have recurring water leaks, foundation cracks, or high humidity, sealing alone won’t solve the root issue.
