The past few mornings we have heard a distinct tapping noise apparently coming
from the other side of the adjoining wall in our 3 bed semi.
This happens at more or less the same time (07:00) each day. The
tapping lasts a
few minutes, stops, then starts again. After about an hour there is no more
tapping for the rest of the day!


Central heating switching on at 7am and pipes through joists etc.
expanding?
