We are planning on putting a mirror to cover the TV hole above our
fireplace. The plan is to remove minimal trim, place shims on the sides
of the existing opening so the mirror is flush with the back edge of the
mantel and the existing trim.

I plan on cutting this backing board so it would fit into the opening,
and holding it in with quarter round or similar.

What would be best for this backing board. MDF, plywood, etc.

Should the mirror be bonded to the backer board. If so how?

I plan to remove the electrical plug, put wire nuts on each wire and
wrap the ends in tape. I am going to do nothing with the phone and
cable jacks that are there.

Any comments.


Thanks.

Those abandoned electric wires would still be connected, so the hot
wire remains hot? I believe that's a potential future fire hazard,
wire nuts and electrical tape or not. I am thinking rodents and teeth
when I say that.

I suspect code would require a junction box with a cover that provides
access to the wire ends, but I am not an electrician and I haven't
bothered to check the code.
