Crown molding separating from ceiling?

Apparently, caulk is the way to go, but you have to be careful of the type. Some are less flexible than others or have a larger shrinkage factor. Here's a link with some info;

For our house, the builders painted the walls a cafe color and the trim dark chocolate brown. The spaces were not even noticeable until we painted everything white!!

So, paint the walls a dark tomato red and the crown all black, LOL!

You have two choices, the first is to try to do it your self and probably waste a lot of time and money, the second is to hire a finish carpenter and let him/her do the job and show you how at the same time. By the way if you start with the second choice it will look a lot better and be very very much less expensive.

If the gaps are 1/2" or less, use a paintable, flexible caulk to fill the gaps before painting. Dap is a good brand.

The house is settling and may need to be inspected by a home inspector
