Model/Mesh Fractures Im new to blender, and new to the site. Ive researched my questions on the internet, and asked a few people, and they all basically sent me here. So i was hoping that I could get some assistance.

So Im new to blender, and starting to model some of my own assets for a Game my colleagues and I are building. Here is my current dilemma. 

As I venture further into my model, and I lop cut and drag, and I extract shapes and build I come out with amazing results. However, when I add a subsurface modifier, and start to do more intricate details, and adding little things here and there, I am finding that my mesh is starting to fracture. When I turn the subsurface modifier off, if all recorrects itself.

Im getting, for lack of a better term, "phantom" faces and 
edges and these "semi filled" faces appear and I cant figure out how to get rid of them. Im spending HOURS trying to figure out how to repair all my beautiful work, and I really think that solving the actual problem is something I should think about doing. So please, any assistance, would be most appreciated. 

I can add a couple of images to further my explanations, if needed and someone can tell me how.

Thanks Community

There are Faces inside your model that shouldn't be there. 


The best way to remove them is in Edit Mode select the bottom edge press "X" and select  "Only Edges and Faces" from the drop down menu.


Also, selecting Smooth Shading in Object Mode will clean this up.
