What pier and beam repair costs under a Huntsville house
Crawl-space houses are the bulk of Huntsville's older stock, from the 1950s brick ranches in south Huntsville to the farmhouses up the 231 corridor, and their repairs are priced by the piece: so much per pier, per joist, per beam. The pieces add up differently under every house. This is how.
Under a pier and beam house the floor sits on joists, the joists on beams, the beams on piers, and the piers on whatever the builder found: a concrete footing, a flat rock, or in older houses nothing much. Madison County clay moves, the piers move with it, and over sixty years the floor develops a slope, a bounce or a soft spot. Repair means putting good support back under it, and the price is a count of parts and the labor to get at them.

Three jobs, three prices
A soft spot by the bathroom
One pier that has sunk under a long-leaking tub drain, two joists gone punky from the same leak, floor bouncing in a four-foot patch. One new block pier, two sistered joists, maybe a short piece of beam. $1,200 to $2,600. The plumber's bill for the drain is separate and comes first.
A sloping hallway
The center beam has dropped an inch and a half over 24 feet because the three piers under it sat on bare clay. Three new block piers on footings, the beam jacked back to the survey line, shims at the neighbors. $2,800 to $5,200, two days.
The whole 1962 ranch
Floors out by two and a half inches corner to corner, half the piers leaning, a beam with a rot pocket near the back porch, wet clay underneath. Laser survey of every room, nine new piers, four re-shimmed, one beam section, a day of cribbing and jacking in stages so the plaster does not crack, then the re-survey. $9,500 to $14,000, four to six days, and the drainage recommendation on the same sheet so it does not happen again.
What the technician checks before pricing
- Every pier, with a level and a hand on it, for lean, crumbling block and missing footings.
- The beams at every pier and at the ends, with a probe for rot.
- Joists under bathrooms, kitchens and the back porch, where water lives.
- The sill on top of the foundation wall for rot and termite damage, which changes the job and the trade.
- Floor elevations with a laser in every room, written down so the lift has a target and the re-survey has a comparison.
- Where water enters and sits, since wet clay is why the piers moved.
What makes crawl-space work expensive
Height. A 30-inch crawl space is a workplace; an 18-inch one is a hardship, and the labor line reflects it. Then ductwork, plumbing and wiring laid where the jacks need to go. Then the stuff people store under houses, which has to come out before anything else does. If you can clear the access door and the first few feet yourself, the sheet gets shorter.
A pier and beam job of $10,000 or more is residential work that Alabama requires an HBLB-licensed contractor to do. The crew's number is on the findings sheet; look it up before you sign.
What people ask about this
Is a steel pier worth the extra over block?
Under a house that is going to keep moving a little, yes, because it can be re-shimmed from a wrench without rebuilding anything. Under a house on a sound footing that just needed one pier replaced, block is fine and cheaper.
Will leveling crack my walls?
It can, which is why a crawl-space lift is done in stages over a day or more, an eighth of an inch at a time, and why plaster houses are lifted less aggressively than drywall ones. Hairline cracks at door corners are normal and are patched; anything bigger is avoided by going slow.
Can you fix it from inside the house?
No. Pier and beam repair is done from the crawl space. If the access is inside a closet floor, that is where the crew goes in; if there is no access at all, cutting one is the first line on the sheet.
How do I know the piers were the problem and not the soil?
The inspection tells you. A pier that has leaned on a sound footing is a pier problem. A footing that has sunk into wet clay is a soil problem and may want a helical pier or drainage rather than another block stack.
Does the house need to be empty?
No. You will hear jacking and some creaking during the lift, and you should keep off the floor above the work for safety while it is up on cribbing, but the family stays home.
