Document the condition
Jot down where the issue is in the Birmingham house, when it happens, how it tracks with weather, whether it's changed over time, and any prior repair attempts -- photos and rough measurements make the first conversation go further.
Read the local context
Start by establishing what kind of below-grade space this is, because the ridge suburbs produced daylight and walk-out basements cut into a slope, and those are loaded from one side rather than evenly. Then find where the water shows: a wet line along the joint where wall meets floor points somewhere different from a damp patch halfway up a wall. Walk the uphill side after a storm and see where the ground sheds toward the house, and check where the downspouts currently end, since that is the cheapest thing to change and often the largest single factor.
Ask what will be hidden
Roof runoff, site grading, hydrostatic pressure against the wall, cracked mortar joints, and stubborn interior humidity often look alike on the surface, yet each traces back to a different repair in a Birmingham basement. Once the Birmingham job is finished, the prep work and verification steps disappear from view -- the written scope is what should describe them.

Line up Birmingham proposals side by side and check protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order terms.
What official local sources add
This is the trade most likely to need the permit the city names. Exterior work on a below-grade wall means excavation, regrading and a new discharge route, and inside a mapped flood hazard area that is development requiring a floodplain development permit rather than an ordinary building permit. Establishing status first therefore changes the sequence of the job, not just its paperwork. The stormwater division's picture matters too, because on hilly ground the streams, detention sites and pipes it maintains are where a sump discharge ultimately goes, and that destination is not the owner's to choose freely.
