How to Extend a Deck and Fix Rotted Support Posts
by Bhupendra Mistry
I have a 10x12 deck that is 10 feet high and 20 yrs old. Its attached to the house and supported by square posts made of 2x10. The support posts and beam are 8 feet out from the house.
The support posts need to be replaced. There were set in concrete and may be softening inside.
I want to extend the deck by 2 feet in length and width to make it a 12x12 deck.
What is the minimal that I need to do?
