Signs Your Crawl Space Needs Repair

If you notice any of these issues with your crawl space, you should have your crawl space inspected:

Musty Odors

If mold is growing in your crawl space, you may smell a musty, damp, or unpleasant odor. Have your crawl space repaired right away to prevent mold from spreading into your home and causing allergic reactions or damaging drywall, wood floor joists, insulation, and carpets.

High Energy Bills

Humidity, cracks, leaks, and moisture issues in your crawl space lead to high energy bills. Consider repairing your crawl space to eliminate moisture intrusion and air leakage, making it easier and cheaper to maintain a comfortable temperature inside.

Sinking Floors

Water and humidity issues in your home’s crawl space can damage floor joists and wooden supports, leading to sagging or bouncy floors. Repairing your crawl space will enhance its structural integrity and keep your floors stable and even.

Crawl Space Moisture

Leaks, condensation, and high humidity levels often cause moisture in crawl spaces. Reliable crawl space encapsulation in Gladstone, MO, eliminates moisture problems and helps maintain your home’s structural integrity.

Condensation

Too much moisture buildup in your home’s crawl space leads to condensation, mold and mildew growth, and pest infestation. Encapsulating your crawl space prevents moisture problems and helps you maintain a healthy space.

Pests

Pest infestation is a major sign that you need to repair your crawl space. Proper crawl space repair properly seals the area and prevents destructive insects from entering your home.

Why Should You Get Your Crawl Space Repaired 

Repairing a crawl space provides the following benefits for your home:

Improved Indoor Air Quality

Crawl space blocks out moisture and prevents humidity issues and water seepage. When your crawl space area is dry and clean, it prevents mold growth and pest infestation. This improves your home’s indoor air quality and protects you and your family from health issues.

Enhanced Home Value

When you repair your crawl space, you improve your home’s structural integrity and aesthetic appeal, which enhances its value. If you decide to sell your home, it will be in excellent condition without expensive foundation issues, making it an attractive option to potential buyers.

Prevents Mold Growth and Pest Infestation

Our team properly seals all the entry points in the crawl space repair process, which prevents pest infestation. This helps you improve indoor air quality and create a barrier between your home and the ground. Crawl space repair maintains humidity levels and prevents water seepage, which reduces the risk of mold growth.

Satisfied Customers

Fast and good!
A sump pump was installed very quickly.
Gerry and Davan were excellent. They protected the house and basement from extra dust and just going in and out to get the tools.
Digging up the yard to install the pipe...they replaced the sod and cleared the extra yard waste. Also they were very friendly with our dog.

Gerry, Davan, and Mario came to check the new installed sump pump. Made sure everything was working.
I'd give everyone 10 stars if I could!!!!

Satisfied Customer Reviews

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!
We recently had foundation repairs with multiple piers and poly-fill. Not only were they professional on-site, but one of the employees even noticed a package sitting outside starting to get rained on so they placed it in my mudroom. They kept me informed through the process and ensured I understood each repair prior to commencing.
Fran was incredible! He was prompt and very knowledgeable about our questions regarding our foundation. He showed us that we already had a bracing system and our foundation was secure. I would recommend him to anyone!
Fran Heisinger came out and gave a detailed and thorough inspection of our foundation. His experience, service and expertise assured us if we needed additional work, his crew and company could do the job. Highly recommend.
We recently used KC Waterproofing to do our foundation, put in an IBeam and jack post, multiple piers. When I say these guys did an excellent job from start to finish… I can’t even express it enough. Very professional. Very clean work. They cleaned up so well you can’t even tell we just had major work done. This was a week and a half project. The entire crew has just been so amazing in this hard time. I will forever recommend and be using them for future projects. I don’t quite remember every one’s name but the ones I do, Cam, Kyle, Jacob, Jesse, Gerry, Connor, you all were amazing and fantastic job. Start to finish!
The team showed up exactly when they were supposed to. They kept us informed with everything they were doing! The entire experience was excellent‼️
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!
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.
We are very happy with the service we received from KC Waterproofing.
We had a very good experience with KC Waterproofing foundation repair on our house in south Kansas City in February and highly recommend you give them an opportunity to look at your foundation for an estimate and any work to be done.
