I had crown moulding recently installed in the LR. There are noticable gaps between the pieces of moulding. The contractor came back and filled them, but they separated again. How can I fix them?

Thanks for your help.

Where are the gaps?

The corners, the top / bottom or at the joints between two pieces?

How long did it take for the gaps to appear, after a winter/summer season?

Is your home new (trusses) and is the location of the room's ceiling at the trusses or is there another floor above?

The crown mdf poplar or a hardwood?

If you would rather you can use the crown molding forum on my site and look over "how to install crown molding" in the owners notebook.. or simply use any search engine they will bring it up in the top ten. Then you can place a picture if need be.

... I'll take a wild guess though, you have primed MDF crown and the installer never let the crown aclimate before install, then over the seasonal change you are getting cracks in corners & joints... for this the only solution is to fill & touch up with paint.

The crown would need to uninstalled then hung with scarf joints & copes, after it was allowed to aclimate for at least 3 days. MDF crown needs to sprung into place as well, if it fits loose it will seperate with the changing weather. If you have trusses and in an cold climate that requires a special installation, if you are in a wet climate mdf would require proper sealing before install.

Laslty it may be also that your home may flucuate with damp/cold to dry/hot for which you will get minor sepertaion, even with the more stable poplar trims.

It appears as if your installer is trying to repair the situation, minor shrinkage is acceptable in most applications. It depends on what is happening...
