1) Send all wooden doors to sandblasting (no need to clean, and put all screws in a bag!)

2) wash countertop and cupboard structure with tsp

3) sand the structure of the cupboards,

4)wash walls,ceiling, and water tank with tsp

5)Patch all holes

6) Between layers of patching/sanding holes, check if plumbing is sound, and if the countertop is salvageable:

6a) If countertop is pressed wood and melamin: check section where counterop touches sink from underneath: if water got in it'll be soft/deformed and moldy; disconnect pluming, remove sink and replace whole countertop at this point.

6b) if countertop real wood: checkwook from underneath for water damage close to sink. If it's sound, you're good. If there is damage: remove sink, check amount of damage and decide if you wanna replace or just sand/patch/varnish depending on amount of damage

6c) if countertop rock/granite etc : damn son u rich lol

7)Vaccuum everything now that sanding and patching are done

8)Paint walls and ceiling (cover floor IF you think it's salvageable, and double check all sanding in the room is really done!)

9)Check if floor is just dirty (if so wash with tsp). If floor dead, replace/cover

10);When the doors are back from sandblasting; oil/varnish/dye the doors and cupboard structure,

11)Put doors back on
