I hope that this is posted in the right spot. Last night in our house when I came up from the basement I smelled what smelled to me like hot rubber. Some friends of mine thought it smelled like sharpie, or burn. I am terrified of house fires and we almost called the fire department because of how incredibly strong and sudden the smell was. The weird thing is it wasn't in any of our rooms, it was mostly in the little "hall" in the middle of them all and really the strongest heading up the stairs to the upstairs. We have ruled out everything like any light fixture, heater, appliance, chemical...absolutely nothing new was brought in or done yesterday that could cause it. We immediately turned off all the lights and the furnace and turned them back on maybe an hour later. The smell dissipated and pretty much went away by 1:00am. My husband was really concerned and stayed up all night just to make sure it didn't come back.
Our house was built in 1950 and we have never had a problem with the electrical but it has also not been looked at. Should we be concerned?
