Someone please help me. Our house is four years old and has done this from the beginning. We live in a quadlevel with smoke detectors linked together and also on battery. Usually the smoke detector at the top of the stairs (with the attic above of course) drips water and at about 2 a.m. would set off all the detectors in the house. We took it down. We now have two more detectors leaking (this only happens in the winter), which are all on the second floor beneath the attic, and we took them down too. I just went to change a light bulb in the same hallway and find rust on the screw from the light where water has been dripping down into the light. We have a five month old and this is freaking me out. I was raised in a firefighter household and having these down so they don't bark is not working for me. My husband works long hours and have asked the guys he works with and they have all come up with something different. We have blown in insulation and the corners of all our upstairs bedrooms sweat also. Should we get rid of the blown in insulation or is there someway we can insulate all the holes in the ceiling? Sorry so wordy, just worried about my big and little guy!
