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 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.
Mario was professional and courteous. He got the work done on time and as described. I would call for his services again!
Great price, great work! In just 3 days, Jesse’s team added two sump pumps and over 40’ feet of channeling with the full wall systems. No more towels, fans, and dehumidifier after every big rain storm!
We were very pleased with KC Waterproofing and Foundation Repair. The foundation specialist, Camden Bales, explained the process we would need to fix our foundation. We felt very confident in the work that was going to be completed. The crew, headed by Jackson Kleeman, worked very hard every day and kept us well informed of their progress. They arrived on time every day and cleaned up before leaving each night. They were polite, friendly, and knowledgeable. Overall, we are completely satisfied with the job that they did. When they finished, you couldn’t tell that work had been done. Great job!
Sump pump backup pump activated an alarm so I scheduled a checkup to make sure everything was fine. Mario called before coming and was very polite. He showed up on time and got straight to work, I was not home at the time and asked him to call me with the results. He diagnosed the problem and then called me to run through results and also provide some more info on the pump operation. Very easy to work with, good communication, smart guy. Would use him for service again.
