The link shows a photo of the small gap of space between the baseboard and flooring on an exterior wall in our home. I’m not sure if there used to be some kind of quarter round/shoe molding there that was removed but the interior walls don’t have any. I’d like to seal the space to protect against outside and basement draft, bugs, etc. but am not sure what would work best for this or how to do it so it isn’t an eyesore since it’s in a main living space. Thank you!
