Mezuzah

From Halachipedia

Having one's Mezuzot checked

  1. One should have one's Mezuzot checked by a sofer once in every three and a half years, and it is a pious practice to check them every year during Elul.[1]

The Bracha on putting up a Mezuzah

  1. If one took down one's Mezuzot in order to have them checked by the sofer and they were found to be kosher, one should put them back up with a Bracha of Lekvoh Mezuzah.[2]
  2. However, if one took down one's Mezuzah just to put it in a nicer case, one doesn't need to make a new Bracha when putting it up unless it was taken down for several hours so that one stopped thinking about the Mezuzah.[3]
