We're building a log home on a concrete block crawl space (4-5 feet high). The floor is sand and we tiled and put in a perforated day drain. And there are small window vents on each wall. We used I-beams for the main floor supports.Due to the heavy rains earlier before our roof was on, the subfloor has been drenched. It will be replaced.But the immediate problem is drying the I-beams. They're covered in mildew & mold & are very damp. How do we prevent them from any further damage?? Do we rinse in bleach solution first? Do we put in forced air heaters? Do we get a large fan & circulate the air to dry it- then bleach it? Help!!

About 3 months ago my wife and I purchased a very large home built in 1830 here in New Hampshire. With the upcoming winter, I am turning my attention to winterizing the basement. The basement runs the full length of the house and has 1 entrance from inside the home and 2 from outside. Half of the basement has concrete walls and floor, the other is dirt floor with original stone walls. The current insulation is scarce, and looks to be in poor condition. My main question is what should I do for insulation in the ceiling in the basement? I also have a moisture/mold problem..I heard something about a vapor barrior but I really don't know how they work or what they are exactly. Any tips and info would be helpful. Thanks in advance.
