Under the floor, one bay at a time.

Older houses in Garland and Richardson often sit on piers and beams over a crawl space. They move differently from slabs: posts settle, shims crush, and beams sag between supports.

What we do

Re-shim where the gap has opened, add piers where spans are too long, sister or replace damaged beams, and check that the crawl space vents and drains.

How it is measured

The same way as a slab: readings across every room before and after, drawn on one sheet.
