Caring for Attic - JEFFREY MAY or other expert

[Guest guest]

I have turtle vents now in attic. Is that likely to be enough, or

should I get a turbine??

Also, do people here think putting an ultraviolet light in my attic

would help clean it of any existing mold? Mold plates done up there

said much higher count than air in area or rest of house. It's a very

old house so perhaps wood has darkened with age, but some wood I can

see grain (wood is dark naturally I believe), but other wood has

charcoal like color so I suspect that could be mold, at least mold at

one time.
