我得讲个长话短说，我很抱歉，但事情并不是简单的解决办法。这栋房子有3张床，建于1940年，前市政委员会，有空腔财产。在楼下，最糟糕的潮湿潜伏在厨房橱柜(外墙)后面，黑霉、发霉、吹碎的木屑、蜘蛛，恶心。外墙是2英尺高的油漆砖，然后进行渲染，朝北，砖的灰泥看起来是咸咸的，就像蜘蛛住在砖里。这是湿气还是冷凝水?我现在在厨房里放了滚筒式烘干机，从墙上通风，所以我想这能帮助干燥厨房内部，目前闻起来像这样。大约10年前，我在客厅的烟囱罩地板(外墙)附近发现了黑色的霉菌，但那只是感觉寒冷和有点潮湿。楼上的浴室(自然)有潮湿的地方在天花板上，我同意冷凝水(窗户打开很多)。最糟糕的是卧室里有令人困惑的sarga。十年前，我拉了一个臭衣柜，发现了大量的黑色霉菌，甚至还有一些绿色的。外面正在下雨，墙上有一小股涓涓细流。 There is an exteriour air brick behind. I striped the paper and painted with damp-stop and left it at that. I left whilst hubby got scrached by thistles on the other side of the garden fence. In the meantime the cavity got filled (no punns there). The room redecorated 2 years ago. 15 months ago the black mold first appered in the very top corner, single wardrobe about 3ft away in the same alcove (ventilated enough?). 12 months ago put two chests of drawers in this alcove the patch still grew and across the top of the chimney brest and started to go green behind the drawers. Had to move rooms again (7 people in our home) 6 months ago big wardrobe in alcove = huge smelly patch of mold. I've been told there is a big overhang to not cause problems, the guttering on the side of the house has forced a dip in the center and spilling over so not possible to be that. No mold on the out side. The render is massively failing but not in that corner. nothing obvious on the roof, joists and roof felt dry. the window in the winter is always wet. Is this just condensation? Why was the mold still growing without furiture in front? And why Green at the bottom of the alcove? If possibly realy bad condensation alone, which is best extraction fans, dehumidifiers or heat recovery (been recomended attic to hallway type) and do you get what you pay for. Can I get away with cheeper option if rendering needs doing aswell?
