Signs Your Home Needs Foundation or Basement Repair

If you see any of these signs, you should consider getting reliable foundation or basement repair services quickly.

Structural and Foundation Damage

Visible structural damage, such as cracks in your drywall, floors, bricks, or exterior foundation walls, indicates that you need foundation repair solutions. A shifting foundation can also lead to sagging, sticking, or failing doors and windows. If you don’t address these structural issues on time, they can escalate and lead to foundation failure.

Garage Foundation Problems

Most homeowners overlook their garage, but the garage is also susceptible to soil settlement and movement. Foundation stress can lead to uneven floors, gaps between the floor and the walls, and a cracked garage floor.

Bowing or Buckling Walls

If you notice your basement walls developing horizontal cracks or curving inward, hydrostatic pressure may be pushing against your foundation. Bowing or buckling walls are serious indicators of foundation issues that can eventually lead to wall failure or collapse if left untreated.

Musty Smells

A musty, damp smell in your basement or crawl space can be a sign of water intrusion. This usually indicates deeper issues such as poor drainage, hidden leaks, or a lack of ventilation, which can lead to structural damage, mold growth, and reduced air quality. These smells tend to linger and worsen over time.

Mold Formation

Mold thrives in damp, dark environments, which makes crawl spaces and basements areas where mold is often found. Visible mold growth on walls, ceilings, wood supports, or insulation indicates that moisture is entering your home and lingering. Addressing and resolving mold growth issues on time helps you protect yourself and your family from respiratory issues.

Drainage and Gutter Issues

If your gutters overflow or discharge water close to the foundation, pooling water can lead to soil erosion, basement leaks, and flooding. Our skilled team helps you address and resolve your drainage issues by installing an exterior drainage system. These systems are designed to direct water away from your home and prevent long-term foundation problems.

Basement Waterproofing in Lenexa, KS

Did you know that at least 40% of the air you breathe on the main floor of your house comes from the area under your home? If you have water or extra moisture in your basement, this can cause problems with the air quality throughout your house!

Our team of experts in basement waterproofing in Lenexa, KS, can come to take a look at your home anytime. Then, we’ll design a sub-floor drainage system specific to your home and your needs. Get rid of extra moisture in your home forever!

Interior Basement Waterproofing

Our interior basement waterproofing system is designed to manage water that has already entered your basement. Through this solution, we capture and redirect water away from your basement using specialized systems.

Interior Drainage Systems

We install interior drain tile to manage water that infiltrates your basement. Our interior drainage system prevents water from pooling and reduces the effect of hydrostatic pressure on your basement walls, helping to prevent cracks and leaks. We provide interior drainage system solutions for homes with recurring water issues.

Sump Pump Systems

Our team installs a high-quality sump pump system that collects water and pumps it away from your foundation. We also install battery backup sump pumps to keep the system running even during heavy storms or power outages.

Exterior Waterproofing System

Our exterior waterproofing systems are designed to provide a proactive approach to basement protection by stopping water before it reaches the foundation. We take the necessary measures to prevent rainwater and groundwater from seeping through the foundation walls, reducing the risk of seepage, structural erosion, and basement flooding.

Downspout Extensions and Exterior Grading

Improper water flow around your home can lead to various basement water issues. Our team addresses all underlying issues and improves the grading around your property by installing downspout extensions. We install downspout extensions to redirect roof runoff away from the foundation, preventing pooling and hydrostatic pressure against the basement walls.

Gutter Covers

We install high-quality gutter covers that prevent clogging while allowing rainwater to flow through your gutter system. These covers reduce the need for maintenance and ensure your drainage system functions optimally throughout the year.

Exterior French Drain Systems

Our team installs exterior French drain systems to efficiently channel water away from your home, preventing water buildup near the basement walls. We provide this solution to homes in low-lying areas or properties with poor natural drainage.

Foundation Repair in Lenexa, KS

Cracks or other problems in your home’s foundation may sound like a homeowner’s worst nightmare, but we will do all we can to make fixing it easy for you. If you think you need a foundation repair in Lenexa, KS, contact our team today.

We’ll get to you quickly, find the problem, and make a plan to repair it as soon as possible. Our team will work quickly and efficiently so that you won’t have to worry about your foundation anymore.

Pier Systems

We install high-quality pier systems to stabilize and lift your home’s settling foundation. Our team installs either push piers or helical piers based on your foundation and property. We drive piers deep into the stable soil beneath your home for added stability. Then, we attach these piers to your foundation with steel brackets, which allows the structure to be lifted and leveled.

Wall Anchoring

Excessive soil pressure or moisture issues around your foundation can lead to bowing or leaning basement walls. That’s why we install a wall anchor system to stabilize bowing walls and straighten them over time. This method stops the walls from moving further inward and can gradually restore their original position.

Carbon Fiber Foundation Repair

Our team provides carbon fiber foundation repair services for walls experiencing minor cracks. We bond carbon fiber straps to foundation walls using high-quality epoxy to stop further movement. This method is quick to install, requires no excavation, and does not take up interior space. Our team offers durable reinforcement that enhances the long-term stability of your foundation.

Concrete Leveling in Lenexa, KS

Concrete can get uneven over time. When the ground shifts, it’s easy for some panels of concrete to end up higher or lower than they were before.

This doesn’t look great, and it can also create a tripping hazard. Even a small movement can make your home more dangerous than it was before. If you need any help with concrete leveling, contact us. We’ll use a process called polyjacking to get your concrete level again so you won’t have to worry and can love the way your home looks.

Reach out to our team at KC Waterproofing and Foundation Repair today! We’ll fix your indoor moisture problems, repair your foundation, or bring your concrete back into true alignment. Before long, you’ll have a home you don’t have to worry about, better indoor air quality, and an overall safer environment for your family.

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!
