You've most likely packed up belongings for a move, so you will understand how the first part of this process works: gather as many clean, sturdy boxes as you need. The tricky part of packing is deciding what to box up, what to keep out, and what to take to Goodwill. An average kitchen remodel can last 4-8 weeks. So, you will not have easy access to the stored items for a period of time. You will also need to find a place to store the boxes in your home, or elsewhere.
Consider packing or moving fragile items close to the space being remodeled. This will ensure they do not get dirty or damaged during the project. This includes wall decorations as vibrations during the remodeling process could damage them.
As you pack, there may be a few items you will need to use during the remodeling. Pack these in a separate box or near the top for easier access. Remember to label your boxes.
Don't wait until the last minute to start packing. You will want to finish this before the remodeling starts. If you are using a temporary kitchen, you will need to set this up with all the necessary supplies prior to kicking off the remodel. While unlikely, if your project gets delayed, resist the urge to unpack kitchen items.
