Signs You Need Professional Repair

Here are some common signs of foundation, crawl space, and basement issues that require professional repair services:

Structural and Foundation Damage

Structural and foundation damage can appear in the form of visible cracks in the walls, horizontal or stair-step cracks in the foundation, sagging floors, misaligned doors and windows, and gaps between walls and floors.

Bowing or Buckling Walls

Bowing walls can severely impact the strength and stability of your foundation. Walls begin to bow when hydrostatic pressure is exerted by the soil around the foundation. If you notice walls bulging inward, you may need bowing wall repairs.

Musty Smells in Your Basement and Crawl Space

A musty smell coming from your basement and crawl space can be a sign of moisture problems. The smell can spread to other parts of your home and impact your indoor living space.

Mold Formation in Your Basement and Crawl Space

Mold usually appears in damp and dark corners of homes. Damp basements and crawl spaces are the areas in your home that are most prone to mold growth. If you notice grey, black, white, or brown mold patches on walls and floors, it indicates you have a moisture problem in your home.

Water Seepage

Common signs of water seepage are watermarks or efflorescence on the walls and floors. Water seepage may result from cracks in the foundation, hydrostatic pressure, or poor drainage.

Cracks in Foundation Walls or Floor

Do not ignore cracks in your foundation walls or floors. They may indicate underlying structural issues like a settling foundation, soil movement, and hydrostatic pressure.

Our Foundation Repair Solutions in Gardner, KS

We address foundation issues with the following repair solutions:

Pier Systems

We use pier systems to stabilize and strengthen settling foundations. Depending on the needs of your foundation, we install helical piers or push piers. Both of these are permanent repair solutions and require minimal maintenance.

Wall Anchoring

Our wall anchoring systems offer a reliable solution for cracked or bowing foundation walls. We use high-strength steel anchors to connect leaning walls to an earth anchor in the stable soil outside your foundation. This gradually pulls the wall back to its original position and reinforces it, preventing further damage.

Carbon Fiber Foundation Repair

Our carbon fiber foundation repair is an effective technique for fixing foundation cracks. It involves using high-quality carbon fiber strips and then securing them to damaged walls. This non-invasive fix provides durable reinforcement and helps maintain structural integrity.

Foundation Repair, Basement Waterproofing, and Crawl Space Repair in Gardner, KS

Our Basement Waterproofing Services in Gardner, KS

We protect your basement against water intrusion with the following waterproofing solutions:

Interior Drainage Systems

Our interior drainage system includes the installation of a RapidFlow Drain SystemTM. This system is designed to manage water entering your basement. It channels water to the sump pit and prevents water accumulation in the basement.

Sump Pump Systems

Our sump pump system offers protection against basement flooding and prevents the risk of water-related issues. We install high-quality, reliable pumps for lasting protection. They collect excess water in your basement efficiently and direct it away from the property through a discharge line.

Downspout Extensions and Exterior Grading

We install downspout extensions and fix your exterior grading so that your basement remains safe from rainwater. Downspout extensions direct rainwater passing through the gutters away from your basement or crawl space, while negative grading of the landscape around your property helps water drain away from the foundation.

Gutter Covers

We install gutter covers to prevent gutter blockage. When the gutter is open, debris may accumulate and block the water, leading to water spilling out over the side of the gutters and pooling around your foundation. Our gutter covers channel rainwater away and prevent water from pooling around the basement.

Exterior French Drain Systems

Our exterior French drain system is designed to divert groundwater and surface water away from your property before it enters the basement. We install a French drain system around the basement perimeter and customize it to fit the layout of your home.

Our Crawl Space Services in Gardner, KS

We implement the following solutions for crawl space repair:

Crawl Space Repair

Our crawl space repair services address various problems like cracks and moisture issues in your crawl space. From installing and replacing support posts to stabilizing the floor, we utilize specialized repair techniques to keep your crawl space safe and strong.

Crawl Space Encapsulation and Dehumidification

Our crawl space encapsulation seals the space, protecting it from external elements like moisture and pests. We also install dehumidifiers to reduce the humidity inside your crawl space. These solutions are efficient and minimize the risk of moisture issues and musty smells.

Crawl Space Drainage Systems

We install drainage systems to prevent water from seeping in and pooling in your crawl space. These systems work by collecting water and channeling it away from your crawl space. This is an effective solution to ensure lasting protection against water infiltration.

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.
