The boards on my deck are about 1" thick. I want to add on to my deck
and the boards are now 1 1/4" Apparently sometime recently they made
them thicker. I am not willing to replace the whole thing. So aside
from shimming the end boards on the old deck and thus having a hump,
what else can I do? I have been calling around to see if anyone has
any stock of the older boards but so far no luck.
I did this on my old deck. I had a few 5/4 planks that needed to be
replaced, but could only find the 2" anymore. I had to remove a couple
extra boards to make room for the router, but it wasn't to hard to do.
One inch sounds a bit thin. Is this wood or some material like Trex?
You could with a router cut approximately 1/4" deep "joist slots"
on the bottom of the deck boards and thereby preserve most of the
strength of the decking and all of the joist strength. You could probably
get away with doing it only in the vicinity of your old decking.
As another poster mentioned, if it is wood, watch for shrinkage from green.
