Just bought this house built in the US in 1956. I had the house tested for asbestos before we did any demo, which came back negative, but I’m now having doubts. Area A was covered in a beige tile. I had someone rip it up and that’s how it looked after. I just pulled up carpet adjacent to area A. I’m assuming B was what was originally in area A, and at some point a previous owner pulled that up (leaving that tiny square of evidence). But I highly doubt that any testing was done or any precautions were taken, and I have no idea how long ago this happened. Area C is what’s under the carpet, some kind of tile. So, assuming this is all asbestos: what’s the danger in the house with the guys who pulled up the tile on what likely previously had asbestos? Is there anyway to safely remove the carpet tack strips? If the house is currently safe, and there’s a safe way to remove the tack, can I encase it all with leveling concrete?

Redoing our kitchen and looking for some advice on the countertop overhang. There will be tall cabinets on either side of standard height cabinets; is it better to (Option 1) order the tall cabs an extra 1.5” in depth so the countertop is flush with the edge of the tall cabinets, or (Option 2) have all the cabs the same depth, and the countertop extend 1.5” past the tall cabs?

We’re a rental built in the ‘60s (US) that has this bathroom mirror that goes from backslash to ceiling. I learned today that both this mirror and the mirror in my kids bathroom (second pic) were attached to the wall with only some kind of adhesive circa 1965. And today, thankfully while we weren’t home, the adhesive in the kids bathroom failed spectacularly. We’re only in the house a little longer but I’d rather not be killed or maimed in a hail of shards in the meantime. So what could be installed to brace this mirror in case its adhesive also gives up the ghost?
