I had done a similar inspection, on probably the hottest & most humid day this summer. I had done the exterior and roof first, and by the time I got inside I couldn't stop sweating.( I was very nervous when I opened the electrical panel W/ moist hands) By the time I got to the crawl space, everything was beading with condensation. The client had concerns about the ventilation. There were 6 vents, and I can't remember how many Sq/FT, but according to my calculations, it actually was sufficient venting. I had informed the client that it was an extreme humid day, and the vents only appeared to be insufficient. I recommended to him, that if the condensation remained to be an issue, he could replace a couple vents with power vents, and that could help with the air flow. I also recommended a dehumidifier since the crawl space was very accessible, and had electrical, and a sump relatively close to the entrance. Do you think these were good recommendations, or what else could I have recommended?
