That is bleeding  
You need wall/floor/ceiling to line up exactly in the corners.  
If they extend beyond then the surface on the outside can receive shadow or light and that can become visible on the inside.

Perhaps you need to play with the Texture Coordinates node for your material - it plugs into all textures you use for your material and you can scale the texture size up or down. Did that door mesh have a texture on it in the program you modelled it in? If it did, is it the same as the texture in Unreal?

> Expressions that perform actions on texture coordinates or output values that can be used as, or to modify, texture coordinates.
