Aside from buying a dehumidifier, what can I do to get rid of this moisture? My problem is our (large) garage. 28x36. Ten foot ceilings, and we do park inside in the winter months. Which of course means we drive in a certain amount of snow/ice. When that melts, we do squeegee it out as best we can. When the temps drop way down (zero and below) we tend to get frost in the corners on the footer-once we even found it on the sheetrock behind some stuff piled into a corner. We have a unit heater installed on the far wall, up high, temp set to around 50 (typically) and two ceiling fans. I keep the ceiling fans going nonstop to help dry stuff up. In addition, along one exterior wall, we have two exhaust fans. I could turn them on, but that means I am dumping heat outside-as well as moisture. We also have a regular diesel space heater that we will turn on when we have a lot of foot traffic in and out-to warm us (and the garage too) in a hurry. Naturally that combustion creates more moisture also. We routinely have humidity levels around 80%, which is too high. Making matters worse is the whole blasted house is tight tight tight-a five star plus rating. (Don't care for it, but let's not go there-it's what we have) So, how can I get rid of this excess moisture in an economical way?
