Time and time again, every time I poke my nose into one of these
forums I see posts that are the equivalent of asking "how long is a
piece of string". often the poster has made up his mind before he asks
a question.
To the OP and just about everybody else who cares to listen, the post
by Joe should be read, read again and probably copied so that you
don't forget.
After 50 years in the game I could not have put it better. He is spot
on.
Just in case you want to check me out look at my brief page on decks.

To reinforce what Joe has said, I am this afternoon going to look at a
house with a structural engineer and a real estate person. The place
has had illegal additions to it, the owner wants to bring these up to
the current standard. The reason for this? The owner wants to sell
but has only had offers up to $320,000. Similar houses in her street
have sold for over $400,000.
It would have cost her a fraction of the cost she is faced with now,
to do it right in the first place.
Cheers
Bill.
