Basement Waterproofing for Kansas City Residents

Through reliable basement waterproofing, your Kansas City home can be ready for any kind of storm. In Kansas City, heavy rain always results in flooding. Our basement waterproofing service doesn’t only restore your flood-damaged basement but also puts effective basement waterproofing measures in place to reduce the risk of flooding in the future. The moisture content inside the basement can create an uncomfortable atmosphere for the residents, but it gives mold the freedom to grow. Since the water evaporates, the problem may begin in the basement. Our waterproofing service can curb this problem and make your basement dry, cool, and mold-free. In addition to repairs, we also aim to protect. That is why we strategically implement preventative waterproofing measures to safeguard your basement and make it a secure place to live and store things. Contact us today for reliable waterproofing service in Kansas City across KS and MO.

Our Basement Waterproofing Services in Kansas City Include

Our professional team of basement technicians is geared up to provide you with comprehensive basement waterproofing services.

Interior Basement Waterproofing

Here are some services that we can perform to protect your basement from the inside.

Interior Drainage Systems

Worker Installing Interior Drain Tile

An interior drainage channel system is installed along the base of the basement wall, on poured or block foundations, to collect water at the wall, the floor, and beneath the floor before it moves to a sump pump and out of the home. The system drains up to three times as much water as a standard basement drain and is built to address six separate ways water can enter a basement. A sealed floor-wall joint closes off the same gap that would otherwise let in radon, odors, and pests, and the smooth-bore, wider-bottom channel design resists the sediment and grit that clog older systems over time.

Sump Pump Systems

Sump pump system with battery back up

Every drainage system includes a sump pump built to handle the water the channels bring to it, with a larger sump pit and backup operation for added protection during power outages or heavy storms. These sump pumps collect water at the low point of the system and move it away from the house before it has a chance to back up.

Stone Foundation Interior Drain System

A stone foundation is made with stones cut into uniform blocks and laid on top of each other with lime-based mortar. If you have this kind of foundation in your house, you don’t have to worry about waterproofing. We can install an interior drain system that will protect it from water and allow it to drain easily.

Crack Injection for Interior

As part of our basement crack repair in Kansas City, MO, and KS, we use a polyurethane injection system. Polyurethane goes into cracks as a liquid and then hardens to seal up the cracks flexibly, and it comes with a transferable warranty. Depending on the cracks, we can also suggest and implement methods that suit the needs of your basement.

Exterior Waterproofing System

To protect your basement’s exterior structure from the water, our experts can perform:

Exterior Crack Injection System

Leaking cracks in your concrete structure need to be sealed to ensure its durability. To do that, we use a reliable exterior crack injection system with waterproofing. The injections we fill the cracks with are filled with polyurethane resin designed to expand with water to block the passage. We provide a lifetime transferable warranty.

Downspout Extensions and Exterior Grading

Downspouts and Exterior Grading in Kansas City

Downspout extensions allow rainwater to flow away from your house by channeling it through the gutter in the basement. Grading is the name given to the slope of the soil around the foundation of your home. Downspout extensions, accompanied by proper grading, are ideal ways to keep your basement away from the water.

Gutter Covers

Gutter covers are essential for keeping your house free from water damage. We can install gutter covers on your roof, allowing the water to drain directly without letting debris block it. The debris stays on top of the gutter, making it easy for you to clean later. As a result, all the water gets drained properly, and you are left with a dry, comfortable place.

Basement Dehumidifiers

Our basement dehumidification service in Kansas City, MO, and KS can examine your basement, test the moisture levels, and install a dehumidifier in an optimal setting. The dehumidification system will keep your basement dry and cool, preventing mold and promoting good indoor air quality. Whatever brand of dehumidifier you choose, it will come with a written manufacturer’s warranty.

Exterior French Drain Systems

Exterior French Drain Systems in Kansas City

An exterior French drain system is typically installed along the exterior perimeter of your house. Its primary purpose is to collect and divert water away from the basement foundation, preventing it from leaking into the house. Depending on the size of your house, we can install the most suitable exterior French drain system to protect your basement from water infiltration. Give us a call to take advantage of our 360-degree interior and exterior basement waterproofing services.

Signs You Need Basement Waterproofing 

If you detect basement damage early, you can save a ton of money and time on extensive repairs. Early detection of water damage would also allow you to stay on top of your basement and strengthen its lifespan.Here are some signs you need to look out for to know when you need basement waterproofing.

Floor Cracks 

Floor cracks are often the result of soil pressure caused by the expansion or contraction of the soil. When the soil beneath and around your basement gets saturated with water, hydrostatic pressure builds up in the soil, pushing it against the basement floor. Eventually, the pressure becomes too much, and the floor begins to crack. If you start noticing floor cracks in your basement, know that it needs waterproofing.

Musty Smells

A musty smell around the basement is a clear sign of mold or mildew. Sometimes, the mold is visible, and sometimes, it grows in hard-to-see areas. That is where the smell gives you the hint. Regardless of the location, mold is extremely dangerous for the house and the people living inside. Therefore, if you smell a moldy, musty scent around the house, it’s important to take a preventative waterproofing measure.

Mold Formation

As mentioned earlier, a musty odor is an indication of mold. However, a clearer indication is when you see the mold formation yourself. Mold can grow rapidly on basement tiles and walls, as well as in other parts of your house. You may also see your wall paint blistering and your insulation going lumpy. Leaving mold as it is can cause severe structural damage and health problems, including respiratory diseases and fungal infections. Therefore, if you spot mold in your basement, get started with reliable waterproofing.

Yes, of course, our company does both interior and exterior waterproofing services. The interior system is designed to be less invasive than the Exterior method. There are times when the exterior method makes sense, like if the basement is finished and can not be undone, then the exterior is a good option, but the same goes for if you have nice landscaping and fixtures on the exterior then you want to move towards the system on the interior. We will help you determine which one is best through our full evaluation process.

Satisfied Customers

Fast and good!
A sump pump was installed very quickly.
Gerry and Davan were excellent. They protected the house and basement from extra dust and just going in and out to get the tools.
Digging up the yard to install the pipe...they replaced the sod and cleared the extra yard waste. Also they were very friendly with our dog.

Gerry, Davan, and Mario came to check the new installed sump pump. Made sure everything was working.
I'd give everyone 10 stars if I could!!!!

Satisfied Customer Reviews

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!
We recently had foundation repairs with multiple piers and poly-fill. Not only were they professional on-site, but one of the employees even noticed a package sitting outside starting to get rained on so they placed it in my mudroom. They kept me informed through the process and ensured I understood each repair prior to commencing.
Fran was incredible! He was prompt and very knowledgeable about our questions regarding our foundation. He showed us that we already had a bracing system and our foundation was secure. I would recommend him to anyone!
Fran Heisinger came out and gave a detailed and thorough inspection of our foundation. His experience, service and expertise assured us if we needed additional work, his crew and company could do the job. Highly recommend.
We recently used KC Waterproofing to do our foundation, put in an IBeam and jack post, multiple piers. When I say these guys did an excellent job from start to finish… I can’t even express it enough. Very professional. Very clean work. They cleaned up so well you can’t even tell we just had major work done. This was a week and a half project. The entire crew has just been so amazing in this hard time. I will forever recommend and be using them for future projects. I don’t quite remember every one’s name but the ones I do, Cam, Kyle, Jacob, Jesse, Gerry, Connor, you all were amazing and fantastic job. Start to finish!
The team showed up exactly when they were supposed to. They kept us informed with everything they were doing! The entire experience was excellent‼️
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!
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.
We are very happy with the service we received from KC Waterproofing.
We had a very good experience with KC Waterproofing foundation repair on our house in south Kansas City in February and highly recommend you give them an opportunity to look at your foundation for an estimate and any work to be done.
