I have almost a 2 inch gap between my wooden floor and wall in the apartment I am renting. I think the dust down there is causing me allergies and I’m worried about the cold AC air escaping down there. Is there a REALLY quick easy way that I can fix it that my landlord is likely to approve? The hole down there is about 10 inches - it is through the floor not just the hardwood planks.
The floorboard are on top of old floorboards that do not line up and neither reach the wall. The coin is a 5 cent coin. Thanks again!
