How about putting blessed silver coins on the threshold?

You can put the coins directly under the entrance door. Pay attention to the number of coins. Generally, even numbers are needed. You can put two coins or four coins.

Generally, when building a house, you can put coins directly under the entrance door. You can make it clear to the construction team directly, and you can prepare directly. When you build the entrance door again, you can put it directly. This is good for your family's geomantic omen, but you'd better choose copper coins, which have a good meaning and can also play a role in ward off evil spirits.
