Pier and Beam Foundation Repair in O'Fallon, MO

Older homes in O'Fallon — and many newer ones in certain neighborhoods — sit on pier and beam foundations. This construction style has real advantages: it keeps the structure above grade and allows access to plumbing and electrical underneath. But it also has vulnerabilities. Wooden beams rot, piers settle, and crawl spaces trap moisture.

Signs a Pier and Beam Foundation Needs Attention

Bouncy or soft floors are one of the clearest signs of pier and beam trouble. You may also notice floors that slope noticeably from one side of a room to the other, doors that drag or stick, or visible gaps under exterior doors. In some cases, you can look into the crawl space yourself and see damaged or missing wood, standing water, or piers that have shifted.

What Repair Involves

For a O'Fallon pier and beam home, repair work typically starts with a crawl space assessment of each beam and pier to develop a repair plan. Repairs can include replacing deteriorated beams, adding new piers for additional support, shimming to level the structure, and addressing moisture sources that are causing ongoing wood damage. Treating the root cause, not just the visible symptoms, is what keeps a repair from needing to be redone.
