Pier & Beam and Crawl Space Foundation Repair

In a pier-and-beam home, the house rests on beams that sit on piers or blocks, with a crawl space underneath. This design is common in older homes across Texas, the South and the Southeast. It is easier to repair than a slab, but it needs attention: supports settle, wood shims compress, and moisture in the crawl space can weaken beams and joists.

Signs of pier-and-beam problems

• Floors that sag, slope or feel bouncy
• Doors that swing open or closed on their own
• Cracks in interior walls and ceilings
• Gaps between baseboards and the floor
• Damp or musty crawl space, rotting wood or wood damage
• Piers that lean, crack or have sunk into the ground

How pier-and-beam homes are repaired

The contractor measures the floors to find the low spots, then goes into the crawl space. Common fixes are replacing crushed wood shims with steel shims, adding adjustable steel posts under sagging beams, replacing rotted sills and joists, and installing new piers where the old ones have settled. Many contractors also recommend improving crawl space ventilation or moisture control, because damp crawl spaces are one of the main reasons wood supports fail.
