What in the room touches the slab?
Take wide photos of walls, garage doors, indoor doors, steps, drains, posts, equipment pads, and outdoor slab edges. Mark the low area on a simple room sketch.
Note stuck doors, unusual water flow, moved equipment, or cracks that reach walls. These facts help with routing but do not prove a cause.
What must be protected or moved?
List coatings, tile, flooring, cabinets, lifts, machines, pipes, drains, conduit, floor heat, and known lines below the slab.
Ask how the provider will handle access, dust, drilling, patches, air flow, protection, and return to use.
When is this more than a slab problem?
Leveling may address a floor slab that rests on the ground. It cannot diagnose foundation movement, wall movement, broken pipes, or building damage from a form.
When signs involve the building or hidden lines, seek the right inspection or licensed expert before choosing a lift.
