Hi, my house has nice bricks on all 4 sides and I need to install a new flashing under the first row of bricks all around without taking the entire walls down. One contractor said that I could remove on one wall, 5 bricks leave 3, remove another 5 and so on, install new flashing in the openning, re-install missing bricks and than do the same with the row of 3 bricks left there for support !. I can do this but is it OK to do it in this matter, is there a better/simpler way of doing this. Thank´s.
