Definition
This foundation system uses wooden or concrete posts (piers) to hold up your house above a crawl space. It's common in older homes and areas with moisture concerns, but the piers need regular maintenance to stay solid.

Pier-and-beam foundations are common in older homes, wet climates, and areas with poor soil bearing capacity. The system creates a raised floor, allowing air circulation beneath the home and easier access to utilities. However, settlement of individual piers can cause uneven floors and structural stress. Inspectors look for sagging beams, deteriorated piers, undersized support systems, and excessive gaps.
Pro Tip
Pier-and-beam foundations need moisture control and regular inspections. Rotted or settling piers are expensive to fix, so address problems immediately.
Example
A 1960s home in Louisiana on pier-and-beam foundation showed severely sloped floors, particularly in one corner. Investigation revealed several wood piers had rotted from prolonged moisture exposure and wood-destroying insects, reducing support capacity. Restoration required replacing all piers with concrete posts and installing new support beams.
