That’s why we provide comprehensive crawl space repair solutions tailored to your specific needs. We look at a wide range of issues to ensure the health and longevity of your home. Call us today!

Our Crawl Space Repair Services in St. Joseph, MO

Significant moisture buildup, plumbing leaks, standing water, and other issues can occur in crawl space regions and result in serious structural issues. Our crawl space repair and solutions in St. Joseph, MO, include:

Crawl Space Waterproofing

It is important to waterproof your crawl area to prevent moisture buildup and water invasion. Our expert waterproofing services include the installation of vapor barriers, drainage systems, insulation, sump pumps, and backup pumps. We safeguard your house from water-related damage and create a healthier living space.

Crawl Space Encapsulation

Crawl space encapsulation creates a controlled environment within the crawl space. This process helps prevent moisture, pests, and structural threats, improving your home’s overall health. Our encapsulation services include sealing foundation walls, floors, and possibly even the ceiling to provide maximum protection.

Crawl Space Dehumidification

Excessive humidity in crawl spaces can result in mold growth, musty odors, and structural damage. Our crawl space dehumidification services help mitigate excess humidity, creating a healthier atmosphere within your home. All of our dehumidifiers are self-draining for easy use. We customize all of our solutions to fit your specific needs and start by providing a free consultation.

Crawl Space Ventilation

Proper ventilation is crucial for preventing moisture buildup and maintaining a balanced environment in your crawl space. With our ventilation systems, you can enhance air circulation and improve the quality of air in your home. We utilize air vents in the crawl spaces so that the air outside can circulate well underneath your living space.

Crawl Space Insulation

Insulating your crawl space is important for protecting it from temperature fluctuations and improving energy efficiency. Our insulation solutions create a thermal barrier beneath your living space, preventing heat loss while also reducing energy costs.

If you are in need of any of these services, don’t forget to call our team today!

Vapor Barrier Installation

Installing a vapor barrier is important for preventing moisture from seeping in through walls, ceilings, and floors in your crawl space. Our vapor barrier installation services provide a barrier against moisture. A vapor barrier helps protect your home from structural damage and reduces HVAC costs. 

Reasons to Get Crawl Space Repair

Don’t ignore the condition of your crawl space area anymore. Repairing your crawl spaces comes with many benefits, such as:

Improved Air Quality

Crawl space repair helps to seal up cracks, fissures, and other spaces in your crawl space area. Once free airflow has been prevented, your crawl space will be protected from moisture. Then, your crawl space area will be protected from mold, and you will have improved air quality throughout your home.

Better Insulation

Our expert installation of crawl space insulation can guarantee that there are no air holes for moisture to escape the crawl space area and move upward. Insulation will lead to better air quality and higher energy efficiency, as well as safeguarding the longevity of your house.

Reduced Energy Costs

Encapsulating the crawl space area helps reduce outdoor air flow and improve the home’s overall comfort, energy efficiency, and air quality by reducing air leakage. With a properly sealed and insulated crawl space, your heating and cooling process will be more efficient, resulting in lower energy bills.

Prevent Flooding

Crawl space repair helps prevent flooding and water damage by addressing issues such as waterproofing, sump pump installation, and drainage systems. By creating a moisture-free environment, you can protect your home from expensive water-related damage.

Increase Home Value

Closed-off crawl spaces raise a home’s value by reducing energy use, enhancing interior air quality, and guarding against water damage. An encapsulated crawl space also keeps out pests and mold, increasing your home’s longevity.

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!

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!
