This week the Fine Homebuilding editors discuss winter condensation, straw-bale homes, punky floor joists, rental-property remodels and more. After getting feedback from a few listeners, Patrick, Matt, and Rob find themselves again discussing the pros and cons of whole-house fans and the process of finding a good contractor. They move on to helping some other folks determine how far to go when fixing up a rental house; how to deal with rotted joists in a drafty crawlspace; if wet windows means there is a serious ventilation problem; and what materials make suitable moisture barriers for sills in a straw-bale house.
