I live in an apt on the side of a pvt house. The house is attached on one side.. the rest of the block is attached on both sides... they are two family houses.

Through the walls I hear a drilling sound but my landlord said he's not drilling and maybe it has to do with the pipes. It sounds like someone is drilling for
About fifteen seconds... then it stops and picks up later on. It happens a
Few times every evening (prob the daytime too but I'm out a lot)

Can this be dangerous?
