We are about to buy a ranch-style house with cathedral ceilings. Because of the ceilings, there is no attic access. One of the points that came up in the house inspection is that the bathroom accumulates moisture and mildew because there is no vent. I've found a website that shows how to install a vent-kit, but it assumes that you can get into the attic to place the vent. Is there any solution to my dilemma that doesn't involve cutting a huge hunk of ceiling out? Any alternatives to a ceiling vent? Any advice would be appreciated.
