Common Signs Your Home Needs Basement Waterproofing

As a homeowner, you should know when to call for professional help to ensure your home’s safety and security. Here are a few common signs to look out for:

Wet Basement

Any type of water or moisture in your basement, including water seepage, leaking cracks, wall stains, and standing water, can be an indication of a serious underlying problem. Not addressing these issues can lead to even bigger problems, such as structural damage and mold growth.

Wall or Floor Cracks

When the soil around your home expands or contracts due to changes in moisture content, the foundation and walls can shift and settle. This movement often causes cracks in the walls or floors, which allows water to seep in.

Musty Odors

A strange and unpleasant smell in your basement can be linked to excess humidity and mold growth, which occurs due to excessive moisture in your basement. A musty smell calls for an immediate inspection and effective waterproofing solutions.

Bowed Walls

Moisture in the soil causes it to expand, which exerts pressure on the basement walls. As hydrostatic pressure increases, this lateral pressure can also cause the walls to bow. If they are not repaired in time, bowed walls can lead to structural collapse.

Basement Flooding

Basement flooding is one of the most prominent signs that you need to waterproof your basement. Flooding can lead to pest infestation, bacterial growth, and excess humidity. If you observe any of these signs in your home, call us for professional basement inspection and waterproofing.

Our Basement Waterproofing Services For Smithville Homes

KC Waterproofing & Foundation Repair takes a comprehensive approach to waterproofing your basement in Smithville. We conduct a detailed inspection of your basement and implement appropriate solutions from the following services.

Interior Basement Waterproofing

Our interior basement waterproofing solutions include:

Interior Drainage Systems

A full-perimeter interior drainage system is one of the most efficient ways to fix a wet basement. It redirects water out of the basement so it doesn’t cause standing water or flooding. We provide homeowners with interior drainage systems customized to suit their basement’s needs.

Sump Pumps

A sump pump is installed in your crawl space or basement and acts as the last line of defense against water. When water accumulates in your basement due to flooding, burst pipes, or clogged gutters, it all gets collected in the sump pit. The sump pump evacuates the water collected in the sump pit outside your property. It can also work together with an interior drainage system to consistently evacuate water from your home.

Basement Dehumidifiers

Basements can easily become damp and humid. We can install a dehumidifier in your basement and ensure optimum levels of humidity in your home that keep your home smelling fresh.

Interior Crack Injections

If your basement walls or floors are cracked from the inside, we can repair them to ensure they are safe from water leaks and water seepage. Cracks, when not addressed, can turn into wide gaps and lead to pest infestation and water infiltration. We use a reliable polyurethane injection system to seal the cracks effectively.

Exterior Basement Waterproofing

We have the following solutions to protect your basement from the outside.

French Drains

An exterior French drain system is installed along the exterior perimeter of your home. Its primary purpose is to collect and divert water away from the basement. We thoroughly inspect your basement inside and out and, depending on its construction, install a French drain system to protect it from water intrusion.

Exterior Crack Injections

If not repaired in time, exterior cracks in your foundation can lead to complex structural problems. Our waterproofing experts seal the leaking exterior cracks in your concrete structure with polyurethane resin, which is designed to expand and block the crack and ensure structural durability.

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.
