Hi all,
I am a new homeowner in an old house circa 1890. the back porch has old tongue and groove on it...looks like 5" .75"....the total size of the porch is about 12 foot by 12 foot..a few the boards have rotted and need to be replaced...my questions are how much do you think it would be to replace the whole porch in a similar tongue and groove flooring? also do they have this stuff at any of the big box stores?

One of the issues we have is we do not want to spend a lot of money on the back porch because one day we will put in an addition and the porch will not be there anymore.

Thanks for your help.
