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.

Mario came out to seal a crack on my stairs and fill a settlement crack in the basement. He was very professional and friendly. He did an amazing job and I was very impressed.
Didn't waste any time. I have a big problem and he told me from the beginning that they couldn't handle it. He helped give me some advice and direction... and did not try to sell me on something he knew they couldn't deliver. I appreciated his upfront honesty and advice.
They are a fantastic company and really went above and beyond to make sure we got the information we needed.
Mario was great! He very informative and helpful! I would highly recommend him!
Mario came out to check the sump pump. After cleaning the pit out and checking both the main and backup pump he wiped everything done and left the area cleaner than when he got there. Very friendly and knowledgeable guy!
Don Derry with KC Waterproofing has been our "go-to" foundation repair specialist since 2005! We have had him to our homes multiple times. The project always wraps up with us having peace of mind. This past time with 14 piers installed, was no exception. His crew was polite and respectful. They cleaned up our property perfectly at the conclusion of the project. I highly recommend this foundation repair company.
Tech was on time completed the repair as necessary, and the experience was great.
We recently had KC Waterproofing out at our home in North Kansas City, and I cannot say enough great things about Ryan Marshall and his team (Austin & Jacob). They worked at our property over the week of July 17/2025 - and absolutely blew us away with their professionalism, work ethic, and transparency.

Ryan took the time to thoroughly explain the problems we were facing, what caused them, and exactly how they were going to fix them. His honesty and willingness to go the extra mile truly set him apart.

Ryan and his assistant worked hard, were respectful of our home, and made sure everything was done right the first time. It's rare these days to find that level of care and craftsmanship. Because of professionals like Ryan, we’ll continue to turn to KC Waterproofing for future needs.

Highly recommend this company—especially if you get the chance to work with Ryan and his crew! When it comes to foundation issues we will always recommend KC Waterproofing. They have been in the business, are trusted, and will do the job correctly.
