Issues with your crawl space can become very costly to fix over time if they are not addressed. If you suspect damage or other issues with your crawl space, call KC Waterproofing and Foundation Repair, the experts in crawl space repair in Grandview, MO.

Don’t Ignore Your Crawl Space

Your crawl space is impacting you even when you can’t see it. About 40% of the air you breathe on your home’s first floor comes from the crawl space or basement. That’s why ensuring your crawl space is in good health is critical to your family’s well-being.

Finding the Right Crawl Space Solution

Each crawl space is unique and must be addressed with a tailored solution. We get to the root of the problem and find the right solution.

Crawl Space Drainage System

A drainage system is meant to address water issues, such as standing water, and is installed prior to the encapsulation process. We connect the drainage system to our sump pump liner and install a pump to remove the water.

Crawl Space Encapsulation System

We use a patented crawl space encapsulation system to completely seal your crawl space. This system prevents ground vapors and odors from getting into your crawl space by creating a layer of protection between the dirt floor and your living space.

Crawl Space Dehumidification

When your crawl space is sealed, the moisture level also needs to be controlled. Our dehumidification system brings the humidity down to below 50%, a safe level that prevents excess moisture, mold, and mildew growth.

Mario was super friendly and professional. The job was done quickly. We are very happy with the work and have peace of mind with the warranty provided.
We recently had foundation repairs with multiple piers and poly-fill. Not only were they professional on-site, but one of the employees even noticed a package sitting outside starting to get rained on so they placed it in my mudroom. They kept me informed through the process and ensured I understood each repair prior to commencing.
Mario is the best guy they have. Thank you for hearing my concerns and addressing the issue. Appreciate your professionalism.
Great crew (Schylur and Marvin). Very customer focused.
KC Waterproofing and Foundation Repair did an excellent job on my sump pump installation and crack repairs. Gary and Davan were not only skilled but genuinely thoughtful throughout the process. We had a bit of miscommunication early on, and instead of brushing it off, they listened carefully, acknowledged what happened, and adjusted their plan so everything aligned with what I needed.

They brought me in at every step—showing me options for the pump location, explaining the exit pipe decisions, and making sure I felt confident about the work being done. Their friendliness and respect made a stressful home repair feel manageable.

I’m grateful for their care and would absolutely recommend them.
