You have now completed the mitzvah of affixing mezuzahs. Your home proudly displays its Jewish identity, and you've tapped into this unique spiritual connection. But you're not finished yet. The mezuzah is a holy object that must be properly maintained to retain its holiness.
At least twice in seven years, we take down our mezuzahs and have them professionally checked to ascertain that they are intact. The scribe examines the scrolls to ensure that no letters have been cracked or erased and that the mezuzah is still kosher. Our vigilance keeps our mezuzahs performing their function: bringing holiness, protection and merit throughout our home.
