causes of water leaks in basement
June 8, 2021

#1: Under the Footer

It’s common in the construction industry to leave a small space between the footer and the poured foundation floor. But excess water can build up and create pressure, causing water to seep in through this crack. This can cause damage to the inside of your home and make the basement space unusable for living space or storage.

#2: Cracks In Foundation Wall or Mortar Joints

Excess moisture in the soil around your basement walls can build up and create pressure, which can cause cracks in the foundation and allow water to seep in. If you have concrete block walls, this seeping water may not be visible until it builds up inside the blocks. This can cause mildew and other problems from excess moisture. You might also see water seeping out of the bottom of the wall.

#3: Cracks In Basement Floor

Water can build up in the soil below your basement floor and create pressure, which can then cause water to press through cracks into your basement floor. The easiest way to tell if this is happening is if you see any visible water pooling on your floor, particularly in any low spots. If you don’t see pools of water directly, there are some signs to look for that might indicate that water has previously pooled there. Pay attention to water stains or other discoloration on the floor. Also, look for efflorescence, a white or gray powdery residue of salt deposits that water leaves behind.

#4: Windows and Window Wells

Because basement windows and window wells are located below ground level in a recessed area, they can accumulate dirt, debris, water, pests, and growing plants. Window wells can fill with water during wet weather, seep out through leaks around the window opening, and flood your basement. If older basement windows and window wells have not been properly maintained, they can rust, rot, or corrode, which can create leaks into your home and cause mold or mildew problems.

You need to keep your basement windows and window wells in good shape, to help keep moisture and water out of your basement. Make sure your windows completely seal without any holes, gaps, or cracks around them.

#5: Over the Top of Your Foundation

A heavy influx of water and improper foundation grading next to your home can allow water to get into your basement. You need to make sure your gutters and downspouts are cleaned out, fully connected, and draining freely. Also, check the location of your discharge for your downspouts and your sump pump. We recommend these discharge at least 10 feet away from your property.

Watch where the water flows in your yard, and pay special attention to any pools of water close to your foundation. It’s common for the soil next to your foundation to settle over the course of the seasons, so you may need to add some topsoil next to fill in any low spots that have formed. Focus on a 6-foot perimeter around your home to make sure the soil distinctly slopes properly away from the foundation,

Satisfied Customer Reviews

Great service, everyone is friendly and courteous. They do whatever they can to help you. Great company I would recommend to anyone.
Great team, worked very hard and stayed after hours to install a basement window as they knew a huge storm was on the way. Our basement was super dry following a lot of rain after install/fixing of foundation proving the job was done well! I recommend this company for foundation repair and water proofing to cinder block foundation in old home.
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.
