Signs You Need Professional Repair 

Some of the signs pointing to basement and foundation issues are easy to ignore until they become costly. Here are some common indicators that it is time to call KC Waterproofing for foundation, basement, and crawl space repair:

Structural and Foundation Damage

If you start observing cracks in your foundation walls, uneven floors, and sticking doors in your home, they may indicate underlying issues with your home’s structure or foundation. If your home displays any of these issues, it’s important to have a professional assessment done to prevent additional structural weakening.

Bowing or Buckling Walls

Bowing and buckling walls are not an overnight occurrence. This issue develops over time. Hydrostatic pressure around the basement walls puts more stress on the walls than they are designed to bear. Gradually, this causes the walls to bow or bulge inward. We use wall anchors to stabilize and straighten foundation walls before they completely collapse.

Musty Smells in your Basement and Crawl Space

Persistent odors or musty smells typically signal moisture or mold growth in the basement or crawl space. Most smells can be removed when the source of the smell is addressed as soon as possible.

Mold Formation in your Basement and Crawl Space

Moisture in your basement or crawl space increases the risk of mold growth. Surface mold growth in damp spaces not only affects the air quality but also poses health risks. If these issues are not addressed in a timely manner, they can become hazardous over time to those living on the property.

Water Seepage

Water seepage is caused by the slow and gradual movement of water through porous materials. Water seepage may appear as efflorescence, water stains, or puddles in your basement. It is different than a leak, which is a more rapid flow of water. Water seepage indicates drainage issues or foundation cracks that can worsen over time.

Cracks in Foundation Walls or Floor 

Horizontal or stair-step cracks in the walls or floor may seem minor, but they can be an early sign of settling or shifting. If the cracks are growing wider or accompanied by other signs of damage, they may indicate serious foundation issues. KC Waterproofing offers permanent repair solutions to address these cracks and restore foundation stability.

Our Foundation Repair Solutions in Lake Quivira, KS

KC Waterproofing specializes in custom foundation repair solutions to restore the stability and safety of your home. We identify problem areas and implement methods that address your property’s unique needs.

Pier Systems

Pier systems address issues related to foundation settlement. We drive steel piers deep into the stable soil below your home to support and lift the foundation, preventing further movement as the weight of your home is transferred to the steel piers.

Wall Anchoring

Wall anchoring is used to stabilize bowing or leaning walls. During this process, earth anchors are installed in stable soil and attached to bowing walls with steel rods. This process gradually stabilizes the walls and restores them to their original position.

Carbon Fiber Foundation Repair

For quick, non-invasive wall stabilization, we use high-strength carbon fiber straps that are directly secured to the wall, preventing further cracking or movement. This offers a durable, simple solution.

Our Basement Waterproofing Services in Lake Quivira, KS

Water intrusion can cause structural issues in your basement. We provide both interior as well as exterior solutions to keep your basement dry.

Interior Drainage Systems

We install interior drainage channels along the perimeter of your basement. This drainage system will collect water and direct it to your sump pump, which then pumps water away from the foundation, preventing stagnant water or flooding.

Sump Pump Systems

We install sump pumps to remove water quickly and efficiently. We install a pump at the lowest point of the crawl space, which allows water to flow towards it naturally. The pump then removes the water from your house.

Downspout Extensions and Exterior Grading

We install downspout extensions to carry water away from your foundation and can regrade the landscape if needed. This helps to prevent water from pooling near your home and reduces hydrostatic pressure.

Gutter Covers

Gutter covers prevent leaves and debris from clogging your gutters, maintaining efficient water flow from your roof and away from your property. This helps prevent overflow and water damage to your basement.

Exterior French Drain Systems

Exterior French drain systems are built around the outer edge of your property to redirect and shed any ground water away from your foundations. This will ensure that hydrostatic pressure limits are kept to a minimal, decreasing the chances of leaks through the foundation.

Our Crawl Space Services in Lake Quivira, KS

We address any foundation, basement, or crawl space with dependable repair, encapsulation solutions, and waterproofing services.

Crawl Space Repair

Our crawl space repair services address and resolve sagging floors, humidity, and wood rot. We can reinforce joists, replace damaged beams, and block any openings to prevent further deterioration.

Crawl Space Encapsulation and Dehumidification

We seal crawl spaces with vapor barriers and install energy-efficient dehumidifiers to control moisture and maintain dry conditions. This improves indoor air quality, which reduces the risk of mold.

Crawl Space Drainage Systems

We install drain tile and sump pumps to drain excess standing water from crawl spaces. This prevents mold formation and protects your home’s structure.

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.
