They took all of the cabinet doors and drawers outside and completed all of the work on them out there. But inside the kitchen, they did have to sand the cabinet frames in place, and that created quite a bit of fine dust. However, they completely covered the floors and counters, all the way to the door, so most of the dust got wrapped up and taken out at the end of the project. They also used plastic sheeting to wall-in the kitchen, to keep dust and fumes contained as much as possible. Nothing got tracked into the rest of the house. But, some of the dust from the cabinet frames also fell into the cabinets, and now I am emptying the cabinets one at a time, cleaning the cabinets, and running the contents through the dishwasher. I'm only working on one dishwasher load at a time, which makes it less overwhelming. I don't really mind, because I'm just looking at it as spring cleaning, and I'm going to donate as much as possible.
