How to fix crown molding separating from ceiling?
Posted on 12/17/20 at 4:58 am

The crown molding is pulled away from the ceiling in most of my house. Here’s a pic of one spot:
There is also molding that has warped in my bathroom, but I assume those just need to be replaced:
Suggestions for fixing this?

I have no idea. How could I tell?
If it needs nails, then the answer is probably no. The previous owner half assed everything in the house.

Doesn’t look like it has nails. Use trim nails, little ones. If you can borrow an air nailer it is much easier vs using a hammer.
Use a little bead of caulk to reseal the edge to look nice. In the winter the dry air and heat in the house makes the wood shrink a little. If the caulks older or too thin it breaks and you see the cracks.
Same where the boards butt against each other.

I’m guessing you don’t have a Finish nail gun and compressor OP? Those are actually really easy fixes but should never do that in the first place.
You need a stud finder, finish nail gun, Brad nails 1.5-2”, and painters caulk.
Use a finish nail gun and put some Brad nails into the studs. So find the studs and shoot some nails into them. Then take some painters caulk between the trim and the walls to seal the gaps back up.
I’m guessing whoever did it did not nail into the studs and just drywall and they are pulling loose.

Use a caulk called “big stretch”

If does not nail in, and there are still large enough gaps, they sell these “caulk saver” foam filler tubes/strips to mash in there to help fill the gap so less caulk is needed (caulk doesn’t just keep pushing in the opening). They work great.

The top photo the OP posted reflects this. This should be able to be repaired by removing the old caulk and re-caulking.
The bottom photo appears to be actual separation of the molding from the ceiling/wall and likely requires re-nailing followed by re-caulking.

This would be my guess also.

This is the correct way to fix it.

I’m assuming I’ll need to paint over the nails?

You shouldn’t need to - 18 or16 gauge finish nails used with a nail gun have a very small head and the heads will be recessed slightly below the wood, if the pneumatic nailer pressure is set correctly
Maybe at most a small dab of white caulk or spackle compound over the nail hole.

You need a pneumatic finish nail gun and use 2 inch 16 gauge nails. Find the studs in the wall and push the crown tight to the wall and tight to the ceiling at the same time and nail it into the wall stud.
Chances are there is no blocking in the ceiling to get a solid ceiling joist, especially if running the same way that length of crown is running. What I do in that case is angle my gun to the left and shoot a nail and then angle the gun to the right and shoot another nail. That way the two nails go through the sheetrock on a 45 degree angle and tend to hold the crown tighter to the ceiling. Then caulk.

the first pic is just old caulk that has shrunk
all you need to do is recaulk
the bottom pic doesn't even look like it has been nailed into place

Where are you located? If I remember correctly don't you live in Cenla? Or did I make that up?
I am local and may be able to help you out with a nail gun.

Good tip.

Does no one cope their crown anymore? Goodtrim carpenters are not cheep
Posted on 12/17/20 at 11:08 pm to Cracker
Not if it will be painted.
Posted on 12/17/20 at 11:12 pm to Cracker
Many don't cope crown or base, can't even run shoe mold and forget setting doors, cabinets, or building closets. Good trim carpenters have moved on because builders are too cheap.

If you cant put your hands on a trim gun buy a box of trim head screws. They work great and hold, will be a larger diameter hole but fillable. Make sure you find the studs and have a good driver drill. I find square drive heads or similar work the best.
