Clay keeps the perimeter damp for a week at a time. The unit holds the whole space steady anyway.
Heavy Spalding County clay holds water against a foundation for a week after rain, so a Griffin crawl space has a damp perimeter far more of the year than the middle. Even after sealing, that perimeter keeps feeding a little moisture into the space.
A dehumidifier absorbs that. It runs steadily through the wet months, holds the space in the fifties, and stops the humidity spikes that follow every long rain. In a shallow crawl space with little air movement, that active control matters more than it would in a taller one.
We size from the measured footprint and load, install a low profile unit where clearance calls for it, and plumb the condensate to gravity drainage since most Griffin lots have fall available. Humidity readings before and after go in the report.
Here is what our crawl space dehumidifier work includes on a Griffin home, in town or out toward the Spalding County line.
