Just moved into a new house that has hot water radiators. In one room (hardwood floors) there is a small gap around the pipe that leads up to the radiator from the basement.
A very strong skunky smell has been coming up from this gap. Exterminators have come and said there is no way there is an animal (alive or dead) in there. I am at a loss, just curious if anyone has any suggestions on what this might be?
