i had a gutter that leaked on my brick home during the end of last winter, i fixed the gutter, but the brick had absorbed enough water to mildew during the spring. and even grew moss. i want to fix it but have no idea where to start? The water also soaked through the wall and cause cracking in the paint inside. I know that it is a solid masonary wall, so my main concerns are drying the walls out, repairing the damage inside ande the mossy grout outside, but i would like to prevent this from happening again or anywhere else on my home. what do i do?
