When you prepare to remodel your kitchen, demolition the existing cabinets is inevitable. Not only cabinets, but also countertops, appliances, flooring and lighting, depending on the extent of your remodel and what you’ve decided to replace. It’s going to get really messy so just be prepared for that and just make peace with the fact that there’s going to be dust everywhere even after the demolition process is finished. You can count on the whole place being dusty and messy for most of the duration of the construction.
Actually during the entire remodel you shouldn’t expect neatness from your contractor. Believe it or not, it is sometimes a lot more efficient to leave things lying where they’ll next be used. It will be messy so just prepare accordingly.
By the way, when demolition your kitchen cabinets, make sure to cover up furniture that you want to protect from dust and will need to either plan on eating out during the remodel or setting up a temporary kitchen elsewhere.
