The frame under the decking in front of summer house has rotten out and decking collapsed. I planned to cut and remove the decking just in front of the house. If I do a straight cut (red line)
on decking this won't be good for the join. Needs to be staggered. Also, plane to use 3 inch fence posts to hold frame off ground. Will need to shovel all the rotten wood out too under current frame
