Our bedroom wall that is an exterior wall has pipes in it that creak, but they only creak when the wind outside blows. What could be causing this? This started a only a few weeks ago. We had a new heating/a.c. system put in a year ago. This is also the same wall as our chimney and was wondering if it could somehow be related to a crack in the chimney lining or something? We just have no idea where to begin or who to call.

Jessica, this is a difficult problem to try to diagnose without being there in person. The most common reason for noises coming from inside walls is the expansion of pipes when they heat up, either because the home is hot water heated or a hot water pipe is connected to a bathroom fixture. The “creaking” noises are generally caused when hot water is run through pipes causing them to expand in holes that were drilled too small. Typically you won’t find water lines in an exterior wall, but it’s not unheard of. Whether you do or don’t have pipes in your exterior walls, we recommend you consult with an expert in your area to help solve your pipe problem.
