I was wondering if anyone had any suggestions to minimize the trenches along foundation walls after foundations have been powerwashed. Also, does anyone have a weed killer or some answer to making the line of green at the bottom of the foundation where it meets the grade go away by the time you leave the jobsite and by the way I have used bleach it dosen't work quick enough for me. One more question pavers and splash blocks with grass coming up in between or around whats the answer to cleaning these without digging up your customers yard.
