In the beginning, there was carpet, and it was hideous and smelly.
Then Mrs. House and Mr. House tore out the carpet, and discovered a hideous black mess underneath, which we were able to clean. And that was good.
Removal of the carpet begat removal of the carpet tack strips (and staples), which was significantly less good.
And then the floor was cleaned by Mrs. House's father, which was wonderful and tedious.
Then our fathers sanded the floor, Mrs. House's father with the huge suction sander (not shown) and Mr. House's father with various hand sanders.
And then it was bare wood. Which needed to be sealed.
Prior to sealing there is the cleaning with nasty smelling chemicals.
Then the sealing of the floor with even nastier chemicals. Followed by more sanding, more cleaning, and more sealing.
And finally, we have a finished room, with a lovely floor, and a lovely Mrs. House watching some Seinfeld.
