Wet wall requiring Basement Waterproofing
June 9, 2021

A wet, leaky basement is a common problem. Basements are underground, making them especially susceptible to water, but that doesn’t mean it’s a problem that should be ignored. When faced with a wet or leaky basement, here are a few things you need to know.

Signs of a Leaky Basement

There are a number of obvious and not-so-obvious signs of a water problem in the basement.

Here are just a few:

  • Visible water. This is an easy one. Don’t ignore it!
  • Water stains. If you see discoloration or water stains on the floor or walls, it may mean you have a problem.
  • Odor. A musty or mildewy smell in the basement may mean there’s a leak or moisture buildup.
  • Mildew or mold. These often harmful growths thrive in humid areas, so if you see them, it may indicate a water problem.
  • Efflorescence. This occurs when the water leaves behind salt deposits, causing a white or gray ash stain on the walls.
  • Spalling. Spalling occurs when concrete or stone peels right off of the walls. This indicates water damage and requires professional service.

Causes of a Leaky Basement

There are countless ways that water can find its way into your home and leak into your basement, and it’s not always easy to determine the source of the problem. Check out these few causes of leaky basement.

Here are a few things to check out:

  • Plumbing. Sometimes the water in your basement isn’t due to a foundation problem. Rather, the leak or moisture is coming from defective plumbing in walls or ceilings. The water eventually finds its way to the lowest point in your home, the basement. Call a plumber if you see a wet patch of drywall on the ceiling or suspect this is the problem.
  • Leaking windows. If your basement has windows, make sure they completely seal without gaps, holes, or cracks. Any defects in the windows could allow water to leak in and cause problems.
  • Cracks in the basement walls or floor. Water in the soil around your basement may seep into the basement through cracks. If you notice cracks in the walls, floors, or foundation, call an expert at KC Waterproofing and Foundation Repair. We’ll be happy to take care of it for you.
  • External water sources. A number of external water sources can cause basement leaks. Check your downspouts, and ensure they are directed away from your foundation. Clear your gutters regularly to stop improper water runoff. And examine your soil grading, as downslopes toward your home may inadvertently drain water right into your basement.

How To Fix A Leaky Basement?

If you notice any of the above signs, try to isolate and stop the water source. Repair downspouts, gutters, and defective plumbing along with regrading your yard to improve drainage.

The best way to deal with a leaky basement is to rely on a professional. KC Waterproofing and Foundation Repair are well-equipped to deal with all types of basement and foundation problems and eliminate your water problem.

Leaky Basement Cracks

With all of the rain lately, your basement is probably having some problems keeping all of the water out. Even a well-built basement can have problems keeping out water in flooding conditions. Most homes are not built to withstand flooding. However, most of our homes are built to withstand some degree of water coming in. If you are seeing leaky basement cracks, you need basement waterproofing. Do not let what seems to be a small problem get worse. You could end up with foundation problems that cost a lot more to resolve.

How To Fix Basement Cracks?

If there is any foundation damage or mold or mildew, this will need to be taken care of before any other work is performed. The mold and mildew will be cleaned up, and then we can check out the foundation to see if it is failing. Depending on the problem, the foundation may have carbon fiber strips used inside the home or it might have push piers or helical piers on the exterior of the home that supports it.

There are a few options in terms of waterproofing your basement. Once the foundation problem is resolved, we would seal the crack. From there, we want to make sure that your basement is protected from any water that wants to make its way in. We would work to install either a drainage system that leads to your sump pump and/or a vapor barrier system that seals out moisture. A sump pump is a must in situations where you are seeing water frequently in your basement. Sump pump installation frees your mind from worry knowing that you will be protected in the event that water comes into the home. Lastly, a dehumidifier will keep moisture at bay.

Can I Ignore It?

In a word, no! Basement leaks and foundation issues may not be an expensive problem, they can worsen, which means problems for your home as well as your pocketbook. If you suspect an issue, contact KC Waterproofing and Foundation Repair today.

Satisfied Customer Reviews

Jeff was very professional and informative. Fortunately we didn't have foundation problems but if we do we know who to call.
Mario was here on time & was very informative about questions I had. A 10 out of 10. Thank you …Mario
This is the second time I've used this company. Great company. They have good employees. Fran did a great job of explaining everything, even the financing. I thought the lending company had great options. When it was time for my French drains to be installed. They came on time and ready. They even did a crawl space protective cover. Great team, they worked well together. Took the whole day but got it all done. Cleaned up well afterwards. The price was reasonable. Jackson explained everything as it went along. Kind, friendly service.
Mario serviced my sump pump today and did a good job. He also replaced tape on my wall shield. He provided excellent customer service and was willing ti come out any time needed or said to call him anytime if I had any questions.
KC Waterproofing and Foundation Repair has taken incredible care of my home through multiple visits. Gary and Davan handled my initial sump pump installation and crack repairs, and they were not only skilled but genuinely thoughtful throughout the process. We had a bit of early miscommunication, and instead of brushing it aside, they listened, acknowledged what happened, and adjusted the plan so everything aligned with what I needed.

They brought me in at every step—walking me through pump location options, explaining the exit pipe decisions, and making sure I felt confident about the work being done. Their friendliness and respect made a stressful repair feel manageable.

Later on, I had some cracks that needed to be reassessed, and Mario came out to take a look. He was incredibly kind, patient, and thorough, and he did an amazing job with the additional repairs. His calm, reassuring approach made me feel completely taken care of.

I also want to highlight Don, the manager, who is just as kind and committed to making sure customers feel heard and supported. It’s clear this team truly values doing right by people.

I’m grateful for their care and would absolutely recommend them for any foundation repair or waterproofing needs.
Mario was professional and courteous. He got the work done on time and as described. I would call for his services again!
Great price, great work! In just 3 days, Jesse’s team added two sump pumps and over 40’ feet of channeling with the full wall systems. No more towels, fans, and dehumidifier after every big rain storm!
We were very pleased with KC Waterproofing and Foundation Repair. The foundation specialist, Camden Bales, explained the process we would need to fix our foundation. We felt very confident in the work that was going to be completed. The crew, headed by Jackson Kleeman, worked very hard every day and kept us well informed of their progress. They arrived on time every day and cleaned up before leaving each night. They were polite, friendly, and knowledgeable. Overall, we are completely satisfied with the job that they did. When they finished, you couldn’t tell that work had been done. Great job!
Sump pump backup pump activated an alarm so I scheduled a checkup to make sure everything was fine. Mario called before coming and was very polite. He showed up on time and got straight to work, I was not home at the time and asked him to call me with the results. He diagnosed the problem and then called me to run through results and also provide some more info on the pump operation. Very easy to work with, good communication, smart guy. Would use him for service again.
Mario did a great job, he was very professional and nice.
