OK, so here's some of the work we've done:
The very first thing to go was this awful burnt orange carpet. Ew.
Under that, we were surprised to find pee yellow carpet. And a fake brick tile entryway. Double ew.
Finally, under THAT, lay the original hardwood floors, in remarkable condition considering the neglect and abuse they've endured.
Note the sweet entertainment center. With a good sanding and lacquering, these floors are going to be awesome. They continue into the bedroom, as well.
Back to that tile entryway. It was GLUED down to the hardwood. Genius.
5 hours with a razor, and I got all the glue up. People, please don't do ugly things to hardwood floors. For the children.
