I am trying to save the mid century blocks that came with my house but every time I close my wooden gate the force shakes the blocks and I’m worried that eventually the blocks will fall away from the wall and break. I’m looking for suggestions on how to secure these blocks to the wall. I imagine they likely moved when the sidewalk foundation sunk. If it’s not a DIY project I’d appreciate suggestions as to the type of professional I would be looking for to fix this.
