How do you find out company made kitchen cabinets?

if they are the same ones that came with your house - contact the real estate developer and try to track it down. also, some cabinet makers will tag all their products - BUT the tag might be very hard to find, look in every nook and cranny and especially at the back of the drawers, etc. It might even be on the back of the cabinets themselves and you wont see it without removing the cabinets from the wall. If they are the same as other houses in your development, go door to door and ask your neighbors, someone might know.
