The.125 is between adjacent joists. 16" on center.
I was thinking the same thing but having never built a deck I was
wondering how accurately aligned the joists are on the average deck.

Seems like it would be easier if it was a conventional deck and I
could use joist hangers.

I'll fix the 4 joists before I move on to the next 5. Thanks for the
opinions!!!

I'll take the last question first. Yes, you should fasten the decking
to every joist. (No exceptions.)

The uneven joists may be an issue. The average person can see a
deflection of an eighth of an inch, and your feet will fell it too.
But it depends on how small of a span the .125 difference occurrs
within. If there is a gradual slope of a total of .125 over a distance
of six or eight feet, then no one will notice.

If the .125 difference is between two adjacent joists, then I'd fix it
before I decked it.

I'm building a deck (1st time building a deck) using cement deck blocks for
support (21 blocks). Deck is 10' x 12' on the side of a AG pool. Each joist
is supported by 3 - 4"x4"s set in the deck blocks. Eack 4"x4" has to be cut
to fit due to uneven ground.

I have 4 joists in place now and I notice they arent perfectly even with
each other. I was using a 2' level to set the hight as I was putting them
in. When I stretch a string across all the joists I can see a variation of
up to .125" from joist to joist. I could go back and shim under some of the
joist but I was wondering how much differance it will make?

Will this variation be noticable when the 5/4 PT decking is screwed down??

Also, Do you have to screw the decking down at every joist? Can you screw
down the decking at every other joist then alternate with the next board??

Thanks for any advice!
