Signs You Need Professional Repair 

Not sure when to call for professional services? Here are a few signs your home needs professional repairs:

Structural and Foundation Damage

Common signs of foundation damage include cracks, gaps, sinking floors, and stuck doors and windows. If you notice these issues in your home, your foundation is compromised, and you must schedule immediate professional repairs.

Bowing or Buckling Walls

Bowing or buckling walls are caused by excessive hydrostatic pressure pushing the soil around your home against your basement walls. A bowing wall is an indication that your basement needs repairs.

Musty Smells in Your Basement and Crawl Space

Musty smells in your basement or crawl space are a common sign of water. In some cases, mold, mildew, and humidity can also cause musty smells in the basement. This smell is a sign that your foundation requires professional attention.

Mold Formation in Your Basement and Crawl Space

Mold formation is not only harmful to your home’s structure, but it also deteriorates your living conditions. Mold spores spread by traveling through the air, potentially leading to health issues and allergies.

Water Seepage

Water can seep into your basement or crawl space through cracks in the foundation walls or floor. These cracks can be caused by soil movement, hydrostatic pressure, or the natural settling of your home over time.

Cracks in Foundation Walls or Floor 

Cracks in the foundation walls or floors can appear in various forms, including hairline cracks, stair-step cracks, and even wider gaps. These cracks often indicate underlying issues such as soil movement or the natural settling of the structure over time. Identifying and addressing these cracks promptly is crucial to prevent further damage.

Our Foundation Repair Solutions in Lake Lotawana, MO

We offer comprehensive foundation repair solutions in Lake Lotawana, MO. Here’s a brief overview of our services:

Pier Systems

Pier systems are a permanent foundation repair solution that supports and stabilizes sinking foundations. We will install durable piers beneath your home under the ground until they reach stable soil, ensuring proper foundation support and preventing movement.

Wall Anchoring

Wall anchoring is a reliable way to fix bowing or cracking walls. We use heavy-duty steel anchors that connect damaged walls to the stable soil outside your foundation. These anchors are gradually tightened to straighten your wall to its original condition.

Carbon Fiber Foundation Repair

Our carbon fiber foundation repair method is a non-invasive solution for weak walls. We use high-quality carbon fiber strips that prevent crack expansion and bowing. It’s an efficient reinforcement technique that protects your foundation without excavation.

Our Basement Waterproofing Services in Lake Lotawana, MO

We offer reliable and efficient basement waterproofing services. Read more about our services below.

Interior Drainage Systems

Within your basement, interior drainage systems are placed along the inner edge of your foundation. These systems collect water that seeps through the walls and floor and redirect it to a sump pump. Our interior drainage systems are a proactive measure against hydrostatic pressure and water intrusion.

Sump Pump Systems

A sump pump system is essential to your overall basement waterproofing system. We install a high-quality, durable sump pump in a pit at the lowest point of your basement. This enables the pump to collect rising groundwater and divert it away from your house, preventing water damage and keeping your basement safe and dry.

Downspout Extensions and Exterior Grading

Our downspout extensions help protect your foundation by carrying water away from your home and preventing it from pooling near the base. Additionally, our exterior grading involves creating a slope outside your foundation so the water flows away from your basement, minimizing hydrostatic pressure and water intrusion.

Gutter Covers

Clogged gutters can cause rainwater to overflow and spill down the sides of your home, potentially saturating the soil with water, damaging your foundation. Gutter covers prevent leaves, debris, and other obstructions from clogging your gutters. We keep your gutters clear and ensure rainwater is efficiently channeled away from your property.

Exterior French Drain Systems

Exterior French drains are installed outside your basement walls. A French drain is made of perforated pipe surrounded by gravel, which collects groundwater before it reaches your basement. The collected water is directed away from your home to a drainage ditch, ensuring a safe, dry basement.

Our Crawl Space Services in Lake Lotawana, MO

Below is a brief overview of our crawl space services in Lake Lotawana, MO.

Crawl Space Repair

Crawl spaces can experience moisture buildup, leading to wood rot, mold growth, and structural damage. Our professional crawl space repair services address these issues and restore the health of your home’s structure. We provide effective repairs to help you create a stable, dry crawl space and ensure a healthy home environment.

Crawl Space Encapsulation and Dehumidification

Crawl space encapsulation involves sealing the crawl space with a vapor barrier to prevent moisture from seeping in. We use a thick barrier to safeguard your crawl space and install a dehumidification system to maintain optimal humidity levels.

Crawl Space Drainage Systems

Crawl space drainage systems are designed to collect and remove water accumulating in your crawl space. These systems often include interior and exterior drains installed along the perimeter of your crawl space. The collected water is directed to a sump pump, which diverts the water away from your home, protecting your foundation structure and indoor air quality.

Satisfied Customers

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!

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.
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!
