Dear Glenn: My home is a one-story ranch house built on a crawl space. The crawl space has the walls and band joists foamed. There are six vents for the crawl space, all open, and there is an outside access door. The crawl space also has a sump pump so that moisture is not a problem.

My goal is to make the crawl space a self-contained space that will maintain a consistent temperature throughout the year. How best can I accomplish this, and can you recommend any area contractors? Much thanks.

Don, Fort Gratiot
