i have a few questions: 1. im thinking of ripping out ceramic tile in my bath and putting bead board up. anyone know what i will find behind the tile? the bathroom was re-done in 1967 and i do believe it is sheetrock above the tile. any one have opinions about bead board in a moist bathroom? anyone have an opinion on the type of wallpaper i should use in a bath room? 2. our house (100+ years old) has a brick foundation and the mortar between the bricks is about half gone. any ideas on the best way to repair this or is this something i dont need to repair in the next 5 years before we sell? 3. we lifted the basement rugs to find layers of cardboard/books/newspapers underneath ( not sure if it was for insulation or ease on the feet). they were soaked in mildew. the previous owners had 2 accidents with leaking water heaters but otherwise it is a "dry" basement. we are letting the mildewed areas be exposed for the summer to hopefully dry out. the cement is crumbling ( cement floor). here are my questions: a. can a person re- cement a floor by themselves or is this a job for the pros? there are specific areas that are good. others need patching. do you patch a floor or do you re-surface it in its entirity? b. is there an ideal way to scrub up the mildew? c. how do you know if you should have a de humidifier? {note: there are 4 separate rooms in the basement, if i buy a dehumid. do i buy 1 to cover the square footage or 2 smaller ones to spread them out or even more than that? i know some of you are pros and probably find my questions dull and repetitive. but this is where im at and im doing the best i can to become self sufficient in home care. so if i have annoyed you, accept my apologies and feel free to ignore my posts. but if i havent, please consider imparting some wisdom this way. i would greatly appreciate it. -mary
