4 1/2 crown ceiling less than 96

Should Crown Molding be even from room to room? I have the skinny Crown that was installed years ago. My house is old and I'm having some renovations done. When the contractors reinstalled the molding in my living room dining room combination it's about 5-10 inches lower in the dining room. I want it even. Am I being to picky by asking this? Please advise!!

Happy to help but would need to see picture of what you refer to. Its fine to have different size crowns if there is a reason for the application.

Hi John, thanks for your response. The Crown is the same size, it's the area located. The living room install is about a 5 to 10 inch difference from the dining room install. It's an open floor plan but it's clearly noticeable when you stand at the entrance of the rooms.
