Moldy and hairy wall properties have not been maintained. Can I not pay the property fee?

If it is a new house delivery, you can go to the developer's house repair department. If it is really caused by housing quality problems such as water seepage, developers have the obligation to maintain it.

But if the problem is not serious, you can wipe off the mildew spots and spray Mrs. Grey's mildew inhibitor, which can kill the mold spores on the surface and prevent mold reproduction. The effect is very good. If you can't wipe off the mildew, you can consider repainting the wall paint.
