Re: should I get my brick house power washed?
I have read that it is best to wet the entire face of the brick with a hose prior to pressure washing.
Then to start at the bottom and work your way up and then back down with the pressure washer.
Do this before the pointing work. Low pressure and avoid positioning the nozzle 90 degrees to the face of the brick.
If your worried about the edges, have the contractor do a small test area out of site.
