Garner soil and why crawl spaces fail here
Garner drains into the Swift Creek basin, where Johnston and Cowarts silt loams hold water at low elevation. Organic-rich alluvial soil retains far more moisture than upland Cecil clay and dries out slowly even during Piedmont dry spells.
Persistently damp soil rots girders and band boards from the bottom up in ranch homes with shallow 18-inch clearances. Musty air is then drawn into the living space through return-duct leaks, so the whole house smells like the crawl space.
Many Garner crawl spaces are tight and low-clearance, which makes debris removal and liner detailing the labor-intensive part of the job.
