These are all great things to do and I hope your home stays protected. I’m a lover of simple and sympathetic magic, so here’s something I would do.
Take something that represents your home. This could be an image, a drawing, anything that connects you to hour home. It could even be a piece of paper with a line-drawing of a house on it labeled “My House”.
Draw a circle around it with a blue pen or marker. Then get the outside of that circle wet. Not dripping wet, but a little damp will do. As you do so, visualize the area around your home as wet and impervious to fire. By creating a representation of what we want to happen and putting our energy behind it, we can affect change in the world sympathetically.
