We haven’t done anything to our house it is 10-12 years old (we lived in 4) there is black mold and two small areas of log rot (no gutters) what do we wash with and what do we treat it with afterward. we have a two sided porch some is not covered, thats were the rot is. who is a repair service in or around Chatsworth, Ga.
The 1st step is to either corn cob blast or wash walls, depending on the type of finish you have. Log replacement, borate, and stain will be neccessary also. A photo of the home will be helpful for a better judgement call. Please call a seamless gutter person in the phonebook, very important to have gutters.
