Document the condition
Write down where the problem is, when you first noticed it, whether it tracks with rain or humidity, how it has changed over time, and any prior repairs. A few photos and rough measurements go a long way toward making that first phone call productive.
Read the local context
Bowling Green sits squarely in south-central Kentucky's karst limestone country, the same geology responsible for the vast cave systems around nearby Mammoth Cave National Park -- the longest known cave system in the world. Lost River Cave, one of the largest underground river cave systems in the country, runs beneath the city itself, and on February 12, 2014, a sinkhole opened without warning inside the National Corvette Museum, swallowing eight Corvettes into a chamber more than 40 feet across and roughly 30 feet deep -- a dramatic, well-documented reminder that karst terrain is an ongoing structural reality for property across Warren County, not a rare event. That geology, combined with a growing population pulled in by WKU, the Corvette plant, and a diversifying regional economy, keeps foundation, drainage, and moisture-related trades in steady demand across the city and the county seats around it.
Ask about what will not be visible later
What you can see growing on a wall or ceiling is rarely the full extent of it. A workable plan has to account for how water is getting in, humidity levels in the crawl space and attic, the condition of the materials themselves, how the work area gets contained, and how the result gets verified once it is done. Ask specifically what preparation and checks happen behind the scenes -- the parts that will not be visible once the job is finished.
Compare complete scopes
When you set two proposals side by side, check how each one handles protecting the rest of the house, getting access to the affected area, material choices, permits, post-work testing, cleanup, restoring finishes, what is excluded, warranty terms, and how they would handle a change order.
What official local sources add
The City of Bowling Green's Public Works and Stormwater Quality programs note directly that Warren County sits in a karst region typified by caves, sinkholes, springs, and underground streams, with very few surface streams to carry away runoff -- which is why the city requires erosion-control and post-construction stormwater plans for qualifying land-disturbance projects. Because karst terrain can produce a sinkhole on one property while a neighboring parcel shows no issue at all, parcel-specific soil, drainage, and flood conditions should be verified with the city before foundation, grading, or exterior work begins.
