Understanding the Basics: What Is Foundation Settlement?
Foundation settlement refers to the downward movement of a home’s foundation due to changes in the soil beneath it. Every house experiences some degree of settling, especially within the first few years after construction. In most cases, this is perfectly normal and expected. However, when settlement becomes uneven or excessive, it can lead to structural damage, water intrusion, and costly repairs.
For Chicago homeowners, understanding the distinction between normal settling and problematic settlement is crucial in protecting your most significant investment: your home.
What Causes Foundation Settlement in Chicago?
Several regional factors make homes in the Chicagoland area particularly vulnerable to foundation movement:
- Expansive clay soils: These swell when wet and shrink when dry, causing seasonal shifts.
- Freeze-thaw cycles: Ice expansion and thawing weaken the ground’s ability to support the foundation.
- Drought conditions: Extended dry periods can shrink soil, creating gaps under your foundation.
- Poor drainage or clogged gutters: Water pooling around the home can erode or soften soil beneath the structure.
- Improper soil compaction: Homes built on improperly compacted fill may experience early and uneven settlement.
How Much Settlement Is Too Much?
While it’s normal for a home to settle slightly, especially in its early years, not all settlement is harmless.
Signs of normal settlement:
- Minor hairline cracks in drywall or around windows
- Slight sticking of doors or windows that later realign
- Small, isolated cracks in foundation concrete
Warning signs of problematic settlement:
- Cracks wider than ¼ inch in walls or floors
- Stair-step cracks in brick or block foundations
- Gaps between walls and ceilings or floors
- Doors and windows that no longer close properly
- Uneven or sloping floors
- Visible separation at foundation corners
If you’re seeing these red flags, it’s time to take action.
