I need to install a new window, about 2'x 3' in a bathroom. The bathroom is on the 2nd floor and the exterior is brick. I have no problem with the carpentry and window installation, but what is the best way to cut the opening in the brick? Do I need scaffolding to cut from the outside or can this be done from the inside? The ground slopes away from the house and it would be very difficult to get scaffolding setup in this location. I can probably finish out the exterior from an extension ladder but I'm not about to try to cut the brick from a ladder. Any advice would be much appreciated. Thanks!
