We had a new fence installed last week - it is 6ft cedar planks, board-
on-board, 8 foot, u-channel steel posts, mounted in concrete.
The fence looks fine, but it doesn't seem as solid as I expected. I
can push it with one finger and the whole fence moves (the movement is
probably as much as 4" back and forth at the top of the fence). It
just feels like someone could push it over fairly easily if they
tried. With steel posts in concrete, I was hoping it would be quite a
bit stronger, more rigid and resistant to movement. I'm not sure if
the posts are bending, or perhaps the concrete foundations weren't set
properly or are not big or set deeply enough, which is causing the
lack of stability. I called the contractor today and he said that the
board-on-board design is not as rigid because the 2x4 cross members
are nailed on wide-side against the fence, rather than horizontally.
This makes sense, but still it seems to have too much "play". He also
should have mentioned the reduced stability of the board-on-board
design when selling us the fence.
If anyone has had this type of fence installed, I'd appreciate your
comments. Does your fence also have significant movement? I'm not
worried about the fence blowing down or anything, just wondering if
it'll hold up long term. I also want to get some assurance that the
contractor didn't perform faulty work by improperly setting the posts.
Thanks for any feedback.
