我真的希望有人可以告诉我正确的方向,我把我的头发。我们买了老房子几年前,发现天气变凉时门楣楼上有严重的渗水。值得一提的是它不做当它湿的,只有当它的冷。整个过梁前面滴上方和底部窗口一路滴。我们的窗户得到冷凝从上到下。我们所有的窗户都换成三玻璃,没有效果。我试着风口的气流,没有不同。我试着底通风口,什么都没有。我清理排水沟时,什么都没有。我试着热涂料和防水膜,没有更好的。 Windows and doors are open all summer, in the winter I used a dehumidifier, still wake up in the morning on cold nights to dripping lintel. The outside is rendered, I have painted the house with masonry weather paint twice, no different. The roof doesn't leak at all and our attic is super dry. What on earth is happening and how can I fix it, having such a wet house is driving me nuts.....
