Change Main Door, Change house Period?

[lili123]

Dear Cecil,
My house is P5, in the past I noticed that the ex owner
of the house had change new windows and new paint, but
like you said those doesn't count. well, this time we
will replace the main door some time in 2009, so do you
think it will change the house Period?
Thank you for you advice.

Frankly, in my opinion, one needs more than that to really change to another Period. Thus, I feel that it is not sufficient.
