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 what will be hidden
Cracks and sticking doors are clues, not diagnoses. Soil moisture, grading, drainage, framing, foundation type, and the karst limestone bedrock common across central and south-central Kentucky all need to be considered together before a repair plan is proposed. The written scope should explain the preparation and verification that will no longer be visible at completion.

Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
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.
