causes of water leaks in basement
June 8, 2021

The last thing that you want to worry about in your home is your basement leaking, but unfortunately, it is a common problem among many homeowners. Luckily, achieving a dry basement in Kansas City is possible with proper professional solutions. Before diving into how you can fix a basement leak, let’s talk about the 5 most common causes of basement leaks in Kansas City homes.

1. Poor or Ineffective Grading

When your home was built, if it was built correctly, builders graded the land under your home to ensure that the ground around your foundation slopes away from the house, not towards it. However, in many cases, homes in Olathe, Kansas City and Overland Park are in need of basement repair due to ineffective or degraded property grading. If water begins to drain in the wrong direction – towards your house – then water begins to accumulate against your foundation and leads to basement leaks in your home. Luckily, a dry basement in Kansas City isn’t just a pipe dream. A Kansas City Basement Waterproofer Contractor will be able to determine if ineffective grading is the cause of your basement leak and provide an appropriate professional basement waterproofing solution.

2.  Cracks in Foundation

Cracks in your home’s foundation aren’t abnormal but it can certainly be a cause for water in the basement of your Kansas City home. Occasionally, cracks in your basement can be the cause of the water. In this case, it’s important to enlist a basement waterproofer in the Kansas City area to assess your foundation and basement, and determine if your foundation cracks and subsequent leaking are caused by hydrostatic pressure or structural problems. From there, KC Waterproofing and Foundation Repair can provide professional wall and foundation repair for a finally waterproof basement in your home!

 3.  Missing or Damaged Gutters and Downspouts

Gutters and downspouts are other essential elements of any home as they channel water away from your home (and, more importantly, your foundation) when precipitation occurs. However, if gutters and downspouts don’t exist or aren’t working properly, water can then be directed towards your home’s foundation, where it can find its way into your basement and cause an excess of moisture in your home. If you don’t already have gutters, KC Waterproofing and Foundation Repair can easily source and install the proper system for your home, leaving you with a dry basement and free of worrisome leaks.

4.  Poor Drain Tile and Sump Pump

A drain tile and sump pump are important elements of any home. A drain tile exists in a home to collect water around your basement foundation and direct it to one of two places. If your home is not on a slope, the water will be directed to a sump pump in your basement where it is then pumped away from the foundation. In some cases, a home may not have a drain tile and sump pump, where other homes simply have an ineffective system. This is where it is important to consider a professional basement waterproofing system to solve for the lack of an ineffective drain tile and sump pump.

 5.  Basement Condensation and Interior Water Leaks

When warm, humid air comes into contact with the cool basement walls and floor of your home, the result is typically condensation. In severe cases, this condensation can lead to significant moisture in your basement, causing you to worry. However, for interior water leaks, the cause is different but still arises from functions within your home. Check for inside basement leaks from areas of your home including your shower, sinks, toilets, the washing machine or dishwasher, or simply just a bad pipe. Trust a Kansas City Basement Waterproofer Contractor to quickly find the source of your basement condensation or leak and provide professional advice on which basement waterproofing system will address not just the leak, but the root cause for your basement leak.

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.
