@Bjorn AhlbladSoap, toothpaste, shampoo, Axe body spray, some clothing, cigarettes, a bunch of scratch off lottery tickets, and a tin mint box of full of methamphetamine. 

Hopefully, they will be able to afford it, and all will be well, and they won't touch anything else (they had sprayed everything with glyphosate, and even severely trimmed back the 2 huge live oak trees in the front yard).

A spray bottle,scorer and scraper.

He suggested 2 options:1: go through and add fireproof 2x4's and use the fireproof spray can foam to seal them (a bit extensive- it's a very large house). 2: use some sort of fireproof "wool"- he uses stuff made by Owen's Corning but I can't see to find it locally unless I'm commercial, which I'm not.

This is not a "throw down some grey laminate, spray on some paint and call it a day house."
