Signs You Need Professional Repair

Not all foundation issues are obvious. Sometimes a small crack, a musty smell, or uneven floors indicate a bigger problem lurking beneath your home. Here are some warning signs to be aware of:

Structural and Foundation Damage

If your floors are sloping or your doors and windows are sticking, it could mean your foundation is in trouble. Things like shifting soil, settling ground, or pressure from underground moisture can cause serious damage to your home. These small signs might not seem like a big deal at first, but ignoring them can lead to bigger, more costly repairs later on.

Bowing or Buckling Walls

If your basement walls are starting to lean, bulge, or curve inward, it’s a sign of too much pressure from wet soil outside. This happens when the ground around your home is saturated with water and pushes against the walls. Bowing walls can completely collapse if they are not restored.

Musty Smells in Your Basement and Crawl Space

If your crawl space or basement smells musty, it’s more than just a bad odor; it means there’s moisture trapped inside. This often happens because of water leaks, poor airflow, or standing water. Moisture can cause mold, wood damage, and make the air in your home unhealthy.

Mold Formation in Your Basement and Crawl Space

If you see mold in your basement or crawl space, or notice the air feels damp, it’s a sign that there’s too much moisture. Mold often grows in wet, humid areas and can hurt your home and your health, especially if you have allergies or breathing problems.

Water Seepage

If you’re seeing water puddles in your basement or crawl space, especially near the walls or in corners, it’s a clear sign that water is sneaking in where it shouldn’t. That unwanted moisture usually means your waterproofing or drainage system isn’t doing its job. Left unchecked, it can weaken your foundation and invite mold.

Cracks in the Foundation Walls or Floor

Small cracks in your foundation walls or floor might not seem like a big deal, but they can be. Whether it’s a thin hairline crack or a wider split, it could point to foundation settling or pressure from water buildup. These cracks can grow, weaken your home’s structure, and let in moisture or pests.

Our Foundation Repair Solutions in Excelsior Springs, MO

Whether your foundation is sinking, cracking, or shifting, we are here to address the issue, prevent further damage, and ensure your home remains safe and stable for years to come. This is how we resolve foundation problems in Excelsior Springs:

Pier Systems

If your floors feel uneven or you’re seeing cracks caused by foundation settling, pier systems can help. At KC Waterproofing, we install strong steel piers, either helical or push piers, deep into the solid ground under your home. These piers lift and support your foundation to stop it from sinking any further.

Wall Anchoring

If your basement walls are starting to bend or lean because of pressure from the soil outside, wall anchors can help fix the problem. We install strong steel rods connected to anchors buried in solid ground near your home. These anchors pull the walls back and keep them from moving more.

Carbon Fiber Foundation Repair

If you’ve got small cracks or slight inward curves in your basement walls, carbon fiber could be the simple fix. At KC Waterproofing, we use strong carbon fiber straps that attach right to the inside of your walls. They stop the cracks from getting worse and keep the wall from moving, all without big, messy equipment.

Our Basement Waterproofing Services in Excelsior Springs, MO

Whether you’re dealing with a little water seepage or serious flooding, we offer comprehensive waterproofing services designed to stop water at its source and protect your home for the long haul.

Interior Drainage Systems

Stop water before it becomes a problem with our interior drainage systems. We install our RapidFlowTM system along the edges of your basement floor to catch water before it spreads. It quietly moves the water to a sump pump, which removes it from your home.

Sump Pump Systems

Our sump pump systems are built to keep your basement dry, rain or shine. They automatically remove water during storms and even work during power outages, thanks to built-in battery backups.

Downspout Extensions and Exterior Grading

Keep water away from your foundation with our downspout extensions and exterior grading. We extend your downspouts and adjust the slope of the ground so rainwater flows away from your home, not toward it. This simple fix helps stop leaks, cracks, and water damage before they start.

Gutter Covers

Our exterior French drain systems quietly protect your home from underground water. Installed around your home’s foundation, they use gravel and special pipes to catch and move groundwater away before it can cause problems. It helps stop basement flooding, soil erosion, and foundation damage.

Our Crawl Space Services in Excelsior Springs, MO

KC Waterproofing’s crawl space services in Excelsior Springs, MO, tackle hidden problems before they turn into costly repairs. Here are some of the key crawl space solutions we offer:

Crawl Space Repair

If you have sagging floors or damage under your home, such as rotted wood or weak beams, we use strong jacks and reinforcements to lift and support everything from underneath.

Crawl Space Encapsulation and Dehumidification

We seal the crawl space with strong vapor barriers and add a dehumidifier to control moisture. This stops mold, wood rot, and musty smells, giving you cleaner air and better energy savings.

Crawl Space Drainage Systems

If water collects or floods under your house, we install drains and sump pumps to prevent flooding. This stops water from building up, which helps prevent mold, rot, and damage to your foundation, so your home stays strong from the ground up.

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.
