Just had bathroom floor re-done after a long slow leak killed it. My domestic partner put another floor on and when he was almost done he discovered water all in the heat vent thing. He called it a duct. We live in a 1969 double wide mobile home and we are attempting to continue fixing it up. It's pretty nice. My contribution has been the decorating part, curtains, etc. I am very not inclined to do much else so thank god for my mans handy skills.
