loops only showing on certain faces, heeeeelp!!

hi all, im attempting to cut some windows and doors out of my building, unfortunately, when i make a loop, the new vertices only appear on certain parts of my model. i want them to appear around the whole building, inside and out. i really dont know what im doing wrong, can someone help?

You don’t make a cut all the way around your model because you don’t have a continuous loop. You have disconnected meshes. Whever your loop cut stops check for errors at those places. Make a continuous mesh and be more careful and think what you want as you model

ok, but what if i merge, will that work?
