Over 40% of the air in your home emanates from your crawl space and/or basement. If your crawl space is wet and musty due to damage, the air in your home is ridden with that same mustiness and potentially hazardous bacteria or mold.

Crawl space repair, in the form of either crawl space waterproofing or crawl space encapsulation, can protect the health of your family. Contact KC Waterproofing and Foundation Repair for crawl space repair in Overland Park, KS.

Why Should You Get Your Crawl Space Repaired in Overland Park? 

A compromised crawl space can damage your home’s structural integrity. Professional crawl space repair in Overland Park, KS, can provide your home with long-term benefits.

  • Improved Air Quality: Moisture, mold growth, and high humidity levels will affect the air quality in the rest of your home. A crawl space that isn’t sealed and insulated may also have a musty odor that can spread throughout your house. Repairing and maintaining your crawl space can improve the air quality throughout your home and help you maintain optimal humidity levels.
  • Better Insulation: Having your crawl space sealed and repaired keeps moisture, pests, and cold air from entering your home. This may reduce the presence of cold floors in your home during cold or damp weather. It can also help you maintain the temperature throughout your home more easily.
  • Reduced Energy Costs: A major advantage of crawl space repair and encapsulation is reduced energy costs. Crawl space encapsulation improves insulation and prevents leaks. This energy efficiency allows you to stay comfortable all year round with reduced HVAC bills.
  • Reduced Radon Gas: Radon is a naturally occurring radioactive gas that can enter your home through the ground and cause severe health complications, including lung cancer. Crawl space encapsulation creates a sealed and controlled environment inside your home. Our durable encapsulation significantly lowers the amount of radon that seeps into your home through cracks and openings in the crawl space.

Our Crawl Space Repair Services in Overland Park 

We offer comprehensive crawl space repair in Overland Park to solve a variety of crawl space problems long term.

Vapor Barrier Installation

Vapor barrier installation is also an efficient way to seal your crawl space and prevent incoming moisture. It keeps your crawl space dry and mold-free while making it more energy-efficient.

Crawl Space Waterproofing

Crawl space waterproofing ensures a moisture-free environment in your crawl space and the rest of your home. Depending on your crawl space’s layout and condition, we implement various proven methods to safeguard it, including vapor barriers, drain tile systems, insulation, and sump pumps. Crawl space interior drainage systems help intercept leaking and pooling water and redirect it away from your house. These systems help prevent flooding and standing water in your crawl space and keep it safe and dry. They are often combined with a sump pump, which collects water in a sump pit and automatically pumps it out of your home.

Crawl Space Encapsulation

To encapsulate a crawl space, we install a heavy-duty polyethylene barrier covering the foundation walls and floors. Encapsulation prevents leaks and water intrusion and keeps your crawl space dry year-round.

Crawl Space Dehumidification

Our crawl space dehumidification service involves installing a high-quality dehumidifier in your crawl space that keeps humidity at optimal levels. KC Waterproofing also provides concrete leveling in Overland Park, KS.

Crawl Space Wall Anchors

Crawl space walls can bow and bulge due to hydrostatic pressure from the soil around your foundation. The best solution for bowing walls is wall anchors. Crawl space wall anchors involve attaching steel plates on the foundation walls, which are connected to an earth anchor with steel rods. Gradually, the anchors straighten the wall and stabilize your foundation.

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.
