Write down what you're seeing
Jot down exactly where it is, when you first noticed it, whether it tracks with rain or humid stretches, how it's changed since, and any repair attempts so far. A few photos and rough measurements go a long way toward a productive first call.
Read the local context
Huntsville's history is unusually legible in its housing, and that is what makes it useful here. The city was settled in 1805 and was briefly Alabama's first state capital after statehood in 1819, but the stock that dominates the metro today came later: when Redstone Arsenal became the center of the country's rocket program after World War II, and Marshall Space Flight Center followed in 1960, the population arrived faster than housing could be built gradually. The result is broad rings of subdivisions put up quickly in a few concentrated decades, mostly over vented crawl spaces, with attic ventilation practice that varied by builder and year. That matters for moisture work, because it means neighboring houses tend to share the same weak point -- and it is why an assessment here should start with the construction era rather than the visible stain.
Ask what won't be visible once it's closed up
What you can see is only a fraction of it. A plan that holds up covers water entry, ongoing humidity, how far the affected materials reach, containment during the work, and a check afterward to confirm it worked. The written scope should spell out the prep and verification steps that get covered over once the job's done.
Line up proposals side by side
Check how each one handles protecting the rest of the home, getting access, the materials they'll use, permits, testing, cleanup, restoring finishes, what's excluded, warranty terms, and how they handle change orders.
What official local sources add
The stormwater program does not govern remediation, and it would be padding to suggest otherwise. Where it earns a mention is one step upstream: most persistent moisture in this metro is a site-drainage problem before it is an indoor one, and the 2020 update to the city's design and discharge standards is aimed squarely at how water is handled on a lot. That matters in a practical way here because Huntsville keeps adding infill beside much older subdivisions -- a new build next door can change where water goes on an established property, and a crawl space that stayed dry for thirty years can start taking water for reasons that have nothing to do with the house itself. Where correcting a moisture source means regrading or altering discharge, current requirements are worth confirming with the city before the work is scoped.

Because so much of Madison County sits over karst limestone, and parts of Huntsville fall inside recognized historic districts, get your specific parcel's flood-zone status, historic-review requirements, permits, and karst-related soil considerations confirmed with the city before signing off on work.
