Through our experiences, $4,000 seems to be the minimum cost of a Kitchen Cabinet painting project. There are many factors that affect the cost of the project. For example, quantity or size of the kitchen cabinets, existing condition of the cabinets, if you’re painting the interiors of the cabinet frames, if you’re using handles or pulls that match the existing holes or if new ones will need to be drilled, and if your cabinets are already painted, are just a few considerations.
