Under a raised home, small wooden posts carry everything.

Under a raised foundation home, the floor is the top of a chain: joists rest on girder beams, girders rest on wood posts, posts rest on concrete pads or piers sitting in the crawl space soil. The chain fails at its weakest link. Moisture is the classic attacker, because water from poor drainage keeps crawl space soil damp, and damp posts rot from the bottom up until they crush or lean. The soil takes its own turn: pads riding on clay tilt and sink a little with every wet and dry cycle, and pads on loose soil simply press in.

The crawl space usually holds honest evidence long before the living space does: posts off plumb, stacks of shims where a handyman chased the sag, wood that a screwdriver sinks into, pads cracked or buried out of level. Upstairs it reads as sagging or bouncing floors, as doors drifting out of latch, and gaps at the baseboards.

Sagging floors and sloping floors are different diseases. A sag is a dip between supports, and it points at the framing chain in the crawl space. A slope is a whole plane tilting, and it points at the perimeter foundation settling. The repair for one does nothing for the other, so the evaluation runs both tests: a manometer floor elevation survey upstairs that maps dips and tilts to fractions of an inch, and a direct crawl space inspection that examines every post, pad, and girder in the affected area, probes suspect wood, and traces any moisture to its source.

You get the findings in writing, with photos from under the house you never have to crawl through yourself. If the evidence says the framing is sound and the movement is old and finished, the report says that instead of proposing hardware.

Failed supports are replaced from inside the crawl space, with no demolition in the living areas. Rotted or crushed posts come out in favor of new supports on proper footings, and adjustable steel jacks go in where girders need lifting: each jack pad is excavated and set on a compacted base sized for its load, then the girders are raised in small controlled increments while a crew member tracks floor elevations above, working toward the most recovery the structure can safely give. Where the soil under the pads is the real problem, we address that too, so new posts do not inherit the old settlement.

What the repair really buys is the end of the shim cycle: a support chain rebuilt as a system, wood, footings, moisture, and soil together, instead of another wedge under a girder. Warranty terms are provided in writing with every proposal.
