If someone is changing his front door old MEZUZAH for a new more HIDUR MEZUZAH. IS A BRACHA MADE for the new one? The old one is kosher i believe, but the new one is HIDUR.
Thank you for your question.
What you are asking is a bit controversial, however most poskim say that you do make a bracha.
Poskim that say to make a bracha- Eshkol pg. 195, Maharam Shick Y:D 285, Tuv Taam V’daas 1-246, Daas Kedoshim -4, Yisodei Yishurun 1pg. 17, Shevet Halevi 2-158 (4), Teshuvos Vhanhagos 2-551, Mezuzas Beysecha 289-6, Chovas Hador 11-14 and ftnt. 28, Agur Boholecha 7-29 that the Steipler said that this is the minhag.
No bracha Maharshag Y:D 57, Shvus Yitzchok 8-20 ftnt. 16 in the name of R’ Eliyashiv zt”l, Oholei Yishurun2- 278 in the name of R’ Moshe Feinstein zt”l.
