Pier & beam is a feature, not a flaw
Unlike a slab, a pier & beam foundation can be adjusted almost indefinitely — that's why hundred-year-old Taylor houses are still standing square. The system is simple: concrete or cedar piers support wood beams, beams carry joists, joists carry your floor. When floors sag or bounce, one of those layers needs attention. Almost never all of them.
The three repairs that cover 90% of cases
Releveling and shimming ($1,500–$5,000). Over decades, piers settle unevenly and shims compress. A crew works through the crawl space with jacks, bringing beams back to level and replacing shims with steel. This is the most common fix and often all an older home needs.
Sill and beam replacement ($2,000–$6,000). Where moisture has reached the wood — usually from poor crawl-space drainage or vanished ventilation — sections of sill or beam rot and crush. Crews jack the structure, cut out the failed sections, and sister or replace them with treated lumber.
Pier replacement or addition. Cedar posts eventually decay at grade; old shallow piers heave in wet years. New concrete piers, properly footed, stop the cycle — and adding piers under a bouncy span stiffens a floor dramatically.
Watch the crawl space, save the house
Nearly every expensive pier & beam repair in this county started as a cheap drainage problem: water pooling under the house, wet-season humidity with blocked vents, gutters dumping at the skirting. If your crawl space stays damp, fix that first — or you'll be paying for beams again in a decade. We cover it on the drainage page.
Common questions
My floors slope but the house is 90 years old. Is that just character?
Some slope is normal in a home that age, but 'character' that gets worse, bounces, or comes with doors that won't close is active movement. A crawl-space evaluation with a level tells the difference — free, and worth doing every few years on a historic house.
Can pier & beam be converted to slab?
Technically yes, practically almost never worth it. Releveling and selective repairs cost a fraction of conversion and preserve what makes these houses good — access to plumbing, adjustability, and the original construction.
How often does a pier & beam house need releveling?
In blackland clay, every 10–20 years is typical, less often with good drainage and ventilation. It's maintenance, like a roof — not a crisis.
What does moisture do under a pier & beam house?
Sustained crawl-space moisture rots sills, invites termites, and cups hardwood floors from below. Ventilation, vapor barriers, and exterior drainage are the prevention trio — all cheaper than one beam replacement.
