Walls – Hearing a popping sound from wall

interiorwalls

Started hearing what sounds like a popping sound coming from inside our bedroom wall. It is part of the exterior to the house, but we have no known water or air ducts along that part of the wall. Any ideas what it could be or who would be able to look at it

Best Answer

Depending what "popping" (I think either popcorn or bubblewrap, neither of which seems likely) means, either:

Dripping water from a roof leak (or from a pipe above traveling a long way sideways, if no pipes in that section of wall - water will go a long way on framing)

or

Some sort of electrical arcing (try shutting off breakers and see if it stops - if it's that, the house you avoid burning down would be your own.)
