A Method I’ve adapted for checking and temporarily repairing wards quickly.
All you need is some paper, a pen and something to channel and read the energy (Crystals are a fine example).
Take your piece of paper and your reader and while holding the reader, close your eyes and try to sense the energy of the space and its wards. Transfer that feeling onto the paper.
Once you’ve envision your ward and space, take your pen (keeping your eyes closed) and start scribbling back and forth weaving the energy together in that spot that you see in your mind.
To help find weak spots that need repair I associate certain energy colors and hot/cold signatures with different needs – which is something you can find or create for your personal associations of your wards.
If you do feel an area needs to be repaired, I thicken the scribbling in that area while weaving the energy in my mind. Vice-versa erasing with pen if needed to be cleansed or cleared.
You can also use this method to bind areas or add sigils/runetic protection to the wards.
