I own a 2-family house ... I live upstairs and rent out the downstairs. I removed all the carpeting on my floor due to allergies. My entire flat has hardwood floors that need refinishing badly.
The problem is that noise travels too easily between floors. Besides my footsteps and my/their entertainment/talking/sex noises, my floor also squeaks and clicks a lot.
The second problem is that smells travel from the 1st floor up to mine. They smoke and cook a lot.
I can't think of any options for quieting the noises ... I can't get to the floor joists and I can't put screws through the hardwood from above because I don't plan on covering it again with carpet.
I also can't think of anything for the smells ... will sanding and refinishing my floors stop them?
