Get the condition on record
Note where you see it, when it shows up, its relationship to rain, and how it's changed. A few photos and measurements help from the first call.
Read the local context
The first question is whether this trade applies to the property at all, since the postwar housing was generally built over vented crawl spaces while the newer communities are largely slab on grade. If there is a crawl space, get underneath and establish the depth, the access, the state of the ground cover and whether the ductwork is intact -- in the older stock these spaces are often shallow enough that access alone limits what can be achieved. Then look outside at where water reaches the perimeter after a storm.
Ask what will be hidden
With a water table that sits close to the surface in flat coastal-plain terrain, planning has to start with drainage and standing water, then work through liner attachment, termite-access gaps, air sealing, equipment placement, and framing condition. Get the prep and verification steps in writing -- they will not be visible after the vapor barrier goes in.
Set proposals side by side
Compare protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
What official local sources add
One honest caveat belongs up front: the city's official pages are not reachable by the automated research behind this site, so nothing here should be treated as a substitute for confirming current requirements with Warner Robins or Houston County directly. What can be said with confidence is that the area grew in successive waves tied to the base and to regional expansion, and that this determines whether a given house has a crawl space at all -- the earlier waves largely do, the newer ones are largely slab. The permitting question that actually matters for this work is usually drainage: exterior grading and discharge typically precede sealing, and those are the parcel conditions worth verifying locally before a scope is set.
