Basement Waterproofing and Restoration for Lee’s Summit, MO

The waterproofing and restoration services we offer for your basement encompass all types of damage your basement might undergo due to moisture. Our experienced technicians utilize efficient methods to keep your basement dry and prevent the risk of water damage in the future. The comprehensive services we offer for your basement waterproofing in Lee’s Summit, MO, include:

Interior Drainage Systems Patented KCW Drain System

We use the KCW Drain System for interior drainage system installation in your basement. This system is suitable for concrete basement floors and is designed to collect water accumulated under the basement. The collected water quickly moves towards the sump pump, which then pumps the water out of your home. Our drainage system is comparatively more efficient than other systems available in Lee’s Summit, MO. It pumps out 30% more water in a few pumping sessions.

Crack Repair

For basement wall cracks, we use the polyurethane resin injection method. We clean the cracks and install injection ports in the affected area. Once the injection ports are placed, a layer of epoxy resin solution is applied to the cracks, which expands into each port. Epoxy penetrates the cracks and offers reliable protection against water intrusion.

Sump Pumps

Our waterproofing service at Lee’s includes KCW Sump System installation. The sump pump system we use has a high capacity and a large sump pit. Whenever water pools in the sump pit, the pump collects it and sends it outside your property. This prevents water damage to your basement due to flooding and clogged gutters.

Basement Dehumidifiers

We use professional-grade dehumidifiers to mitigate moisture damage to your basement. Our professionals thoroughly examine your basement to determine the moisture levels. After the examination, we install a dehumidifier of a suitable capacity. The installation protects your basement from mold, bad odor, and moisture and improves the indoor air quality. If you wish to learn more about our basement waterproofing methods, call us right away. Our basement repair experts will offer you a free consultation with a thorough explanation of our services.

When Should You Consider Basement Waterproofing for Your Home?

You should consider basement waterproofing for your home in Lee’s Summit, MO, if you notice the following signs of damage:

Wet Basement

Look for any signs of water stains on your basement walls and floors. If you find any dark stains, drywall discoloration, or mineral deposits, it is a sign that the basement is wet. Schedule an appointment with us for an inspection immediately.

Floor Cracks

Floor cracks in your basement can lead to water seepage. Hairline cracks in your basement are normal in most cases. However, cracks wider than ⅛ inch pose the risk of water damage. If you notice such cracks in your basement floor, they should be sealed without delay.

Musty Smells

The musty smell coming from your basement is an indicator of mold and mildew formation due to water infiltration. The unpleasant smell degrades indoor air quality and poses a risk of health issues.

Mold Formation

You may notice visible patches of mold in your basement walls, floors, or tiles appearing in different colors, mainly gray, brown, and green. This mold may indicate water damage in your basement, which needs to be taken care of immediately. If you let the mold remain in your basement, the mold will spread throughout the entire building before you even realize it.

Basement Flooding

Heavy rainfall, groundwater, and burst pipes contribute to basement flooding. The flood will leave standing water on the basement floor, leading to all kinds of water-related problems on your property. To deal with flooding issues, you have to install a sump pump and a proper drainage system in your basement.

Wood Rot

If your basement has wooden walls or beams, it is more likely to rot due to moisture. Look for any signs of damage in the wood, such as shrinking, discoloration, and cubical fracture.If you notice any of these signs of damage in your basement, contact our professionals. We will offer a free inspection before you proceed with basement waterproofing in Lee’s Summit, MO.

Step 2: Waterproofing and Restoration

Our technicians will begin the waterproofing and restoration process at the scheduled time. They will arrive at your home with all the necessary tools and safety gear. Depending on the difficulty of the project, our repairs may last 3 to 5 days.

Step 3: Quality Assurance

After the waterproofing and restoration process is complete, we perform quality assurance. We inspect the quality of the work done and ensure the basement is completely dry. We make sure the insulation and installations are functioning properly so that you don’t have to deal with water damage in your basement again.It’s important to understand that simply repairing damage is not enough to keep your basement safe from water issues. It needs regular inspection and maintenance at least once a year. For this, we also offer an annual inspection service. If you want to sustain the durability of the waterproofing process, make sure to contact us for an annual inspection.

Why Choose Basement Waterproofing Services From KC Waterproofing?

No one wants water in their home. Most homeowners think that broken pipes or floods are the most common ways for water to enter a house, but that’s actually not true. In fact, water most often enters a home through the basement. Think about it: the basement sits below ground level. That’s also where water flows when it rains, snows, or when it pours off of your roof or out of your neighbor’s home. When the ground can’t hold any more water, the water still has to go somewhere. That’s when it can enter your home through the walls or cracks and breaks in your foundation. This water can cause a number of problems, from damage to floors, walls, furniture, ceilings, and more to mold and mildew growth and associated health problems. You can avoid all of these problems when you choose basement waterproofing in Lee’s Summit. You’ll save time and money doing this over repairing after water damage, and you’ll save yourself a lot of stress, too!

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.
