ok, I have a water leak somewhere in my house... it's driping down into my laundry room... funny thing is, it doesn't do it all the time, so I can't pin point what causes it. Also, sometimes at night time, I can hear a dripping noise coming from my attick... when I went up there, I didn't see anything, but there is insulation everywhere which makes it quite hard to see. Does anyone know who would be able to trace down this leak and fix it for a reasonable price?
