Hello,
there is 7 x 3.5 m pergola - one side attached to the brick wall and the other side resting on 2 poles.
Tradesman has finished the job but the metal post that is attached to the brick wall has not been fixed properly. 7m length sitting on 3 dyna bolts, and 3 holes on metal post as seen on the pic (without any screw / bolt). I feel concerned that pegola may not be able to withstand rain / storm.
Can you pls guide - what size screw / bolt should I use to complete this unfinished job?
Many thanks,
