This is a very general description of a problem a client is having. Granted, I haven't been to the home, this is from her description:
Client described a noise in a wall. The wall is located in the downstairs master bedroom. There is nothing on the other side of the wall other than the exterior of the house. There are no trees, bushes, gutters, exterior hose bibs,,etc. She is hearing this noise (described as 2 balloons rubbing together and very loud) at night and in the morning. It's a constent sound she hears. We have had very high winds here in Texas and it seems to be making this noise when the wind gets to a certain speed. She does have rats/birds in the attic, but the exterminator said that is no animal making that noise. If any of you need more clarification, please let me know and I will be glad to give you whatever info I have:
Symptoms: Sounds like 2 baloons rubbing together. Only happens at night/morning. Only during high winds. House is on a slab. 2 story house. There is nothing above bedroom other than the attic. No plumbing to think of in that area (so she says).
