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.

Jeff Wolfe was excellent providing a thorough inspection, informing us about the company history, the technology and strategies utilized and our options. I would highly recommend Jeff and KC waterproofing!
First class in every way. Very friendly and accommodating. They do things the right way even if it takes much more time to get the project done. Their job of putting things back the way it was, was spectacular! They even replanted the flowers they had to dig up.

Great company and extremely easy to work with. Riley was my point of contact and he explained everything very well. After I denied working with them on one property (due to family issues) Riley happily messaged me back when I needed help with another property. The solution was a hard one to figure out, but Riley constantly made suggestions that would hopefully solve the issue without doing too much work that isn’t needed. Riley clearly explained what I needed and don’t and also gave guidance for other issues I had going on regarding window sealing.

Schylur Oakes and his crew were the ones that came and worked on my property. Schylur was extremely personable and friendly. He constantly ran back and forth from the back of the house (where the work was being done) to the front of the house to ring my doorbell and ask me if I was okay with what they were doing, if I wanted them to change anything etc. One moment he even came and asked if I really need the work to be done since there were sprinklers near my basement window and maybe that was the issue instead, not foundation and rain water. I clarified that I don’t even use my sprinklers and I still have water entering but I was glad he even brought it up and checked with me before proceeding. Schylur ended the day by having his crew clean up after themselves and showed me around and told me everything they did.

Only issue I had was payment processing was a pain. It’s 2026, I shouldn’t have to give my card number over the phone for a deposit, just send me a link to a secure site to enter it. How can I trust some random number and voice over the phone? Then for the final payment, having to manually type out and input my card information in to a tablet while it was raining was a slight nuisance. I have my own small business and use Square tap to pay. It’s not that expensive. Come on guys, if I’m using it for my little business, you can afford it for your long standing company. Just my 2 cents.
Camden came and did a thorough inspection of our foundation and explained the findings well. I felt he was honest with his recommendations and did not try to convince us to do something that wasn't necessary.
Will use KC Waterproofing and Foundation Repair again and highly recommend.
Thank you Cam!
Very professional, informative and did a great job cleaning up after the job.
Jeff was very professional and informative. Fortunately we didn't have foundation problems but if we do we know who to call.
Mario was here on time & was very informative about questions I had. A 10 out of 10. Thank you …Mario
This is the second time I've used this company. Great company. They have good employees. Fran did a great job of explaining everything, even the financing. I thought the lending company had great options. When it was time for my French drains to be installed. They came on time and ready. They even did a crawl space protective cover. Great team, they worked well together. Took the whole day but got it all done. Cleaned up well afterwards. The price was reasonable. Jackson explained everything as it went along. Kind, friendly service.
Mario serviced my sump pump today and did a good job. He also replaced tape on my wall shield. He provided excellent customer service and was willing ti come out any time needed or said to call him anytime if I had any questions.
KC Waterproofing and Foundation Repair has taken incredible care of my home through multiple visits. Gary and Davan handled my initial sump pump installation and crack repairs, and they were not only skilled but genuinely thoughtful throughout the process. We had a bit of early miscommunication, and instead of brushing it aside, they listened, acknowledged what happened, and adjusted the plan so everything aligned with what I needed.

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

Later on, I had some cracks that needed to be reassessed, and Mario came out to take a look. He was incredibly kind, patient, and thorough, and he did an amazing job with the additional repairs. His calm, reassuring approach made me feel completely taken care of.

I also want to highlight Don, the manager, who is just as kind and committed to making sure customers feel heard and supported. It’s clear this team truly values doing right by people.

I’m grateful for their care and would absolutely recommend them for any foundation repair or waterproofing needs.
