Foundation movement is something most homeowners would rather not think about.
Unfortunately, in the Greater Houston area, it is something worth understanding.
That does not mean every home is going to develop a serious foundation problem. It also does not mean every crack, sticking door, or uneven floor requires foundation repair. But understanding why homes move can help homeowners recognize changes earlier and take steps to maintain their property.
The biggest factor is often something homeowners cannot see at all:
The soil underneath the house.
Why Do Foundations Move?
A house is sitting on the ground, and that ground is constantly interacting with moisture.
In the Greater Houston area, much of the soil contains clay that can hold significant amounts of moisture. When that soil gains moisture, it can expand. When it loses moisture, it can contract.
That cycle can happen repeatedly over the life of a home.
At the same time, the weight of the house is pressing down on the soil beneath it. As the soil expands, contracts, and changes over time, different areas underneath the structure may respond differently.
That is where foundation movement can become a problem.
A house does not necessarily need to move uniformly for homeowners to notice changes. If one portion of the structure moves differently from another, the house can begin to tilt, deflect, or settle unevenly.
That uneven movement is what can eventually show up as cracks, sticking doors, or other changes throughout the home.
Is Foundation Movement Normal in Houston?
Some degree of movement can occur in homes over time.
The goal when constructing a home is not necessarily to create a foundation that will never move under any circumstances. Building a structure to withstand every possible change in the soil would require significantly more engineering and expense.
Instead, homes are constructed according to applicable building standards.
These standards provide minimum requirements for construction. They are important for establishing how homes are built, but meeting a minimum standard does not mean a foundation will never experience movement throughout its lifespan.
In a region with expansive clay soils and changing moisture conditions, some amount of movement can occur over time.
The important question is whether that movement remains relatively stable or begins creating noticeable problems in the structure.
Why Does Houston’s Clay Soil Affect Foundations?
Clay soil has an important characteristic that homeowners should understand: it can expand and contract as its moisture content changes.
During periods of significant rainfall, soil can absorb moisture and expand.
During extended dry periods, that same soil can lose moisture and contract.
This is one reason maintaining relatively consistent moisture around the home can be important.
It does not mean homeowners can completely prevent foundation movement by watering the yard. Even with good drainage, functioning gutters, and appropriate irrigation, soil conditions can still change.
But managing water around the home can help reduce some of the extreme moisture fluctuations that affect the soil.
How Does Uneven Soil Movement Affect a House?
Imagine a house supported by soil that is moving at different rates underneath different areas.
One portion of the structure may remain relatively stable while another area settles or moves more significantly.
That difference can create stress throughout the structure.
This is when homeowners may begin noticing things such as:
- Cracks in walls
- Cracks in brick or brick veneer
- Cracked or broken tile
- Doors that begin sticking
- Windows that become difficult to open or close
- Gaps or separations around parts of the home
- Areas of the house that no longer appear level
These symptoms do not automatically mean a foundation repair is needed.
The important thing is to notice changes.
A crack that has remained unchanged for years is different from a crack that is progressively opening. A door that has always been slightly difficult to close is different from one that suddenly starts sticking.
Paying attention to those changes can give you a better understanding of what is happening with the house.
Can Homeowners Prevent Foundation Movement?
You cannot completely control the soil underneath your home.
However, homeowners can take steps to help manage the conditions around the foundation.
Start with water management.
Make sure gutters are working properly and directing water away from the house. Downspouts should also discharge water in an appropriate location rather than allowing large amounts of water to collect directly beside the foundation.
Drainage matters as well. Standing water or excessive moisture around one portion of the home can create different soil conditions from another area.
Irrigation also deserves attention.
During extremely dry conditions, appropriate watering can help maintain moisture in the soil around the home. During periods of heavy rainfall, however, additional irrigation may not be necessary.
The goal is not to keep the ground constantly wet.
It is to avoid extreme conditions whenever possible.
Why Should You Have Your Plumbing Checked?
Foundation problems and plumbing problems can sometimes be connected, which is why plumbing maintenance is worth including in your overall home maintenance routine.
A leaking sewer line beneath or near a home can introduce additional water into the soil. That can change the conditions around the foundation.
Not every plumbing problem causes foundation movement, and not every foundation issue is caused by plumbing.
However, catching a plumbing problem early can prevent it from becoming a larger issue.
For older homes, regular plumbing checks can be especially useful. The transcript recommends having the sewer system checked approximately every two years, particularly for older homes or newer homes that are outside their warranty period.
If a plumbing professional identifies a problem, addressing it rather than allowing it to continue can help prevent the situation from becoming more complicated.
How Often Should You Check Your House for Foundation Problems?
You do not need special equipment or hours of your time to keep an eye on your home.
Regularly walk around the house and pay attention to things that look different.
Look at your doors and windows. Check your walls. Look at brick or brick veneer around the exterior. Pay attention to cracks, tile, and areas that seem to have changed.
You can do this while completing normal household tasks.
While mowing the yard, cleaning the house, or working outside, take a few minutes to look around.
The goal is simply to become familiar with what your home normally looks like.
That makes it easier to recognize when something changes.
What Should You Do If You Notice New Cracks or Other Changes?
First, do not immediately assume the worst.
A crack does not automatically mean your home needs foundation repair. Homes experience all kinds of changes, and individual symptoms need to be considered in context.
Instead, pay attention to whether the condition appears to be changing.
If you notice new or worsening cracks, doors that suddenly begin sticking, broken tile, or other changes that concern you, consider having the home evaluated by a reputable foundation contractor.
An evaluation can help determine whether the changes appear to be related to foundation movement or whether another issue may be involved.
The earlier you understand what is happening, the more information you have when deciding what to do next.
FAQ: Understanding Foundation Movement
Why do foundations move in Houston?
Houston-area homes are built on soil that can expand and contract as its moisture content changes. Over time, those changes can contribute to uneven movement beneath a structure.
Does every Houston home eventually have foundation problems?
Not necessarily. Foundation movement can occur over time, but movement does not automatically mean a home has a serious foundation problem requiring repair.
Can good drainage prevent foundation movement?
Good drainage can help manage moisture around the home, but it cannot completely prevent foundation movement. Soil conditions can still change even when a homeowner maintains the property properly.
Why does clay soil affect foundations?
Clay can expand when it gains moisture and contract when it loses moisture. Repeated changes in soil moisture can contribute to movement beneath a home.
What are signs that my foundation may be moving?
Changes such as new or worsening cracks, sticking doors or windows, cracked tile, or changes in brick or brick veneer can be reasons to have the home evaluated.
How often should I check my house for foundation changes?
Regularly. A quick walk around the interior and exterior of your home can help you notice changes before they become more difficult to identify.
Can plumbing problems affect foundation conditions?
A plumbing or sewer problem can introduce additional water into the soil around a home. That is one reason regular plumbing checks and prompt repairs can be an important part of home maintenance.
What should I do if I notice new foundation cracks?
Do not automatically assume the crack means you need foundation repair. Monitor the change and consider having the home evaluated by a reputable foundation contractor if you notice worsening cracks or other signs of movement.
Understanding Your Home Is the First Step
Foundation movement can be frustrating, but homeowners have more control than they may realize when it comes to monitoring and maintaining their property.
Keep your gutters working. Pay attention to drainage. Manage irrigation based on weather conditions. Keep up with plumbing maintenance. Most importantly, get familiar with how your house normally looks and functions.
You cannot control the soil beneath your home, but you can pay attention to what is happening above it.
And if something starts to change, don’t ignore it.
