Uneven Floor caused by foundation damage
June 9, 2021

You’re not alone. We’ve all experienced that one spot in your house where it’s not quite flat when you step. Maybe it’s the transition from one room to another, maybe it’s a section of your kitchen, or maybe it’s so bad that the floor in a room of your home is leaning. Maybe it happened so slowly that you thought it would never get bad enough to need a repair, or maybe it happened quickly.

Regardless of what it looks like, KC Waterproofing and Foundation Repair have probably dealt with it. From sloping rooms in older homes to sagging floors in nearly new homes, we’ve seen it, inspected it, and repaired it.

What do Sagging Floors Mean?

Sagging floors can mean a number of things. They might indicate something simple, such as a damaged section of wood on which the floor rests. It could mean that one of the supports for the floor is failing. In these cases, replacement of the damaged area may be needed, or it may be as simple as adding a support brace. Sagging floors could also mean underlying foundation slab settlement and damage, in which case a more extensive repair could be required.

Interior Floor Repair for Sagging Floors

KC Waterproofing and Foundation Repair is your interior floor repair expert From the installation of simple braces to using driven piles to lift an entire section of your home, KC Waterproofing and Foundation Repair can do the job the right away at a reasonable price. We use adjustable steel brackets in conjunction with driven or helical piles to lift and stabilize sagging floors.

Other foundation repair companies use inferior methods, such as shims. Not only do these increase stress on the structure, but they also may need to be replaced later. KC Waterproofing and Foundation Repair use the best products and methods available. Not only that, we provide a free inspection. So if you’ve noticed sagging floors in your home and have been wondering what to do, give us a call. We’d be happy to help.

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.
