Pier and beam repair for the wood-floored ranch houses Huntsville grew up in
The brick ranches that went up across Huntsville in the 1950s, 60s and 70s mostly sit on block or brick piers over a crawl space. Sixty years of damp clay and dry summers later, some of those piers have settled, some have leaned, and the floor above tells you about it. The fix happens from underneath and it is measured from above.
A pier and beam house carries its weight down through wooden floor joists onto beams, and the beams onto a grid of piers that stand on footings in the crawl space. It is a good system for a site that moves, because each pier can be adjusted. It is also a system with a lot of parts sitting a foot or two above damp soil, and in Madison County that soil is Decatur or Dewey clay that swells in a wet spring and shrinks in a hot August. Over decades a pier near a downspout settles while one under the middle of the house does not; a beam that was level develops a sag between supports; joists dry, shrink and pull their nails; and the floor above starts to slope toward the low pier, bounce between the sagging beam and the wall, and squeak everywhere in between.
The symptoms inside are familiar to anyone who has lived in one of these houses: a marble rolls to one side of the hall, doors swing open on their own, a crack opens along the top of a wall where the ceiling has pulled away, the kitchen floor has a soft spot near the sink. None of them are an emergency. All of them get worse slowly, and a floor that has been shimmed with offcuts of lumber by three previous owners is a floor that has been moving for forty years.
The repair begins with a laser survey of the floors from above, room by room, so the low points are numbers rather than impressions. Then the crew goes under. Each pier is checked for settlement, lean, cracked block and a footing that has sunk into the clay; each beam for sag, rot at the bearing points and old improvised shims; each joist for sag, splits and sections that have sat against damp soil. The report maps all of it against the floor readings so the cause of each low spot is identified, not assumed.
Then the fix, which is mostly carpentry and masonry rather than heavy equipment. Settled piers are replaced with new block piers on proper footings, or with adjustable steel piers where the house is likely to keep moving; sagging beams are jacked back toward level a little at a time and supported with additional piers at mid-span; weakened joists are sistered with new lumber bolted alongside; and the whole frame is shimmed with steel rather than wood scraps. The lift is gradual over a day or two so plaster and drywall above are not cracked by a sudden move. Afterward the same laser survey is run and the before-and-after readings go in the report. Where the crawl space is damp enough to have caused the problem, encapsulation is priced alongside, because dry soil is what keeps the new piers where they are put.
What this work includes
Laser survey above, inspection below
Every room read with a rotating laser and every pier, beam and joist checked in the crawl space, so each low spot has a named cause.
New piers on real footings
Settled block piers replaced on properly sized footings; adjustable steel piers where the house is expected to keep moving and future adjustment is worth having.
Beams and joists made sound
Sagging beams supported at mid-span, rotted bearing ends cut back and replaced, weak joists sistered with bolted lumber.
A gradual lift
Jacking in small increments over a day or two, watched from above, so the walls, tile and plaster come along without cracking.
Steel shims, not scrap
The improvised wood shims of past decades come out; steel shims go in and do not compress or rot.
Measured afterward
The same survey points read again when the work is done, with both sets of numbers in the report you keep.

Questions about pier and beam repair
How much can a pier and beam floor be lifted?
As far as it needs to go to come back within normal tolerance, usually an inch or two at the low spots, done in small steps. Lifting an old house all the way to dead level in one go cracks walls and ceilings; the aim is a floor that reads level to the eye and the marble, with the frame fully supported.
Why not just add more shims?
Shims are fine on a pier that is sound and has stopped moving; that is what steel shims are for. Shims on a pier that is still settling, or on a beam that is sagging between piers, are a way of chasing the problem every few years. The survey tells which is which.
Can the work be done without tearing up floors?
Yes. Everything happens in the crawl space. Access is through the existing crawl door, and in a tight crawl space the crew works on their backs. The only time a floor is opened is to replace subfloor that has rotted from below.
Is a damp crawl space really the cause?
Often it is a large part of it. Wet clay under a pier footing is soft clay, and a pier sinks into it; humid air swells joists in summer and dries them in winter so they move. Fixing the piers without drying the space works for a while. Fixing both is what lasts.
Does this need a permit in Huntsville?
Replacing piers under a house is structural work and goes through City of Huntsville Building Services inside the city limits. Re-shimming alone generally does not. The crew files what is needed and the fee is on the sheet; outside the city, the town or county office applies.
What does the HBLB rule mean for my job?
If the total comes to $10,000 or more, the contractor must hold an Alabama residential home builder's licence from the Home Builders Licensure Board. Whole-house leveling often does; a few piers and some sistering often do not. Either way you are told which, and the HBLB number is on the sheet when it applies.
