Sinking Concrete Foundation? Here's What It Means
A sinking foundation happens when the soil beneath your home can no longer support its weight evenly, allowing sections of the structure to settle downward. Left alone, it tends to get worse, not better. Foundation Solutions diagnoses the cause and builds a foundation repair plan matched to how far your home has settled.
What Does a Sinking Foundation Look Like?
Settlement rarely announces itself all at once. Instead, you’ll usually notice a combination of small changes around the house:
- Diagonal or stair-step cracks in exterior brick or block
- Cracks in interior drywall, often near doors or window corners
- Windows and doors that stick or no longer latch properly
- Uneven or sloping floors in one part of the house
- Gaps opening between the wall and ceiling or floor trim
Any one of these on its own can have another explanation, but seeing several together is a strong sign the foundation is settling.
Why Foundations Sink
Settlement almost always traces back to what’s happening in the soil beneath your home:
- Expansive clay soil that shrinks in dry weather and swells when wet, shifting support unevenly
- Poor drainage that lets water erode or soften soil beneath the footing
- Poorly compacted fill soil left over from original construction
- Tree roots drawing moisture from the soil near the foundation
- Age, as soil conditions and drainage patterns change over decades
Concrete cracking is often the first visible clue — see our concrete cracks page for how the two are connected.
Is a Sinking Foundation Serious?
Yes — a foundation that continues to settle can eventually compromise the structural integrity of your home. Call a professional promptly if you notice:

FAQs
About Sinking Foundations
Can a Sinking Foundation Be Fixed Without Replacing the Slab?
In most cases, yes. Methods like concrete lifting and polyurethane foam jacking raise the existing slab back toward level, and piering solutions stabilize the structure above it, without the cost and disruption of a full slab replacement.
How Much Does It Cost to Fix a Sinking Foundation?
Cost depends on how much the foundation has settled and which repair method fits the cause. Our team provides an exact, itemized quote after a free, no-obligation inspection.

Testimonials
I don't even know where to start with this review. From the first contact to the end of the job, Ryan and his crew were amazing - professional, knowledgeable, courteous, tidy and clean and very respectful of the impact the job had on me as the homeowner. The job was major, but I felt confident with the information that Ryan and his crew shared with me each step of the project. Since they are specialists, they are very busy so it took a while from start to finish but worth the wait! I could not be more pleased. They get an A+++ from me.
We had a consultation with a very knowledgeable engineer (Collin) who's extremely patient to answer questions and concerns we had. After a thorough walkthrough and measurements, it turned out the area which we thought might be problematic with leveling is only centralized and minuscule, not foundation-related. I'd like to thank Foundation Solutions for this engineer's detailed explanations, professional knowledge and recommendations. At the end, we acquired peace of mind and would highly recommend this company to anyone that may be seeking help with foundation related issues. If we are doing any addition/expansion of our house, we would definitely get in touch again for securing our foundation.
Kyle and the team are awesome! A corner of our foundation has a horizontal crack and when we go out for a quote, many companies explained how serious it is and give us a high estimation. Kyle came onsite and did a detailed inspection, explain why it crack, and how to properly fix it. Then few days later, gave us a reasonable estimate, and we decided to go with the service, they handled the permit, came to fix it in a day and did all the final inspection and passed, we have a smooth experience on the fix. My family are super happy with their service and already recommend to friends in case they need some work in the foundation.
