The side walls certainly do not seal well and there always seems to be a gap in various places. Truthfully, I¡¯ve never had any water leakage because the aluminum fascia on the outside creates an adequate overlap, but what is definitely a problem is mosquitoes! I¡¯ve found that unless that gap is sealed we are plagued by the biters! A work around is pushing mosquito netting into the space between the side wall and the roof, and we do this every time we set up
