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

Camden came and did a thorough inspection of our foundation and explained the findings well. I felt he was honest with his recommendations and did not try to convince us to do something that wasn't necessary.
Will use KC Waterproofing and Foundation Repair again and highly recommend.
Thank you Cam!
We recently had foundation repairs with multiple piers and poly-fill. Not only were they professional on-site, but one of the employees even noticed a package sitting outside starting to get rained on so they placed it in my mudroom. They kept me informed through the process and ensured I understood each repair prior to commencing.
Fran was incredible! He was prompt and very knowledgeable about our questions regarding our foundation. He showed us that we already had a bracing system and our foundation was secure. I would recommend him to anyone!
Fran Heisinger came out and gave a detailed and thorough inspection of our foundation. His experience, service and expertise assured us if we needed additional work, his crew and company could do the job. Highly recommend.
We recently used KC Waterproofing to do our foundation, put in an IBeam and jack post, multiple piers. When I say these guys did an excellent job from start to finish… I can’t even express it enough. Very professional. Very clean work. They cleaned up so well you can’t even tell we just had major work done. This was a week and a half project. The entire crew has just been so amazing in this hard time. I will forever recommend and be using them for future projects. I don’t quite remember every one’s name but the ones I do, Cam, Kyle, Jacob, Jesse, Gerry, Connor, you all were amazing and fantastic job. Start to finish!
The team showed up exactly when they were supposed to. They kept us informed with everything they were doing! The entire experience was excellent‼️
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!
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.
We are very happy with the service we received from KC Waterproofing.
We had a very good experience with KC Waterproofing foundation repair on our house in south Kansas City in February and highly recommend you give them an opportunity to look at your foundation for an estimate and any work to be done.
