Can any professional tell me that the maintenance of long hair and mildew on the wall of the house is the scope of work of the property?

Hello, this is obviously a waterproof problem, which is caused by moisture. The solution is to deal with the roof, and then you waterproof the next door. Secondly, the indoor humidity may be too high. When choosing waterproof materials, choose materials with strong adsorption and add waterproof coatings. The wall needs to be negotiated with the neighbors, and the roof is completely a property issue. Another option is that since the property can't be handled in time, you can go directly to them, which means that the roof is for your own use and independent use, so that you can handle it yourself, at least your own business. I hope it helps you and me.
