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.

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.
