Tefillin and mezuzot ought to be checked periodically, in case natural processes have rendered the parchments non-kosher.

Your local Judaica place probably has a contact, regardless, or your local frum shul. You might need a prosthetic man; I hope you won’t. 

I can check tefillin and mezuzot if you mail them to me. Doing them onsite is not so optimal, but it can be arranged.
