I have just signed a lease for a very old building. We have begun restoration so we can move our business in within the next year. This evening I thought I heard voice in the cellar so I went down to check it out. But there was no one in the basement. As I walked around the lights turned on by themselves.
Is it possible that old wiring can cause that to happen? Is that common? Is that a sign of really bad wiring... or can motion cause a power surge?
Yikes.
