He does really fine careful work. I used him about 5 years ago to do the masonry for my detached garage, and then I finished it. Everything was square & plumb. The window, door, and the top wall, was so level, that I did not have shim anything. It was unbelievable.
I recently had him come back, to replace part of the back wall of my house, that had buckled due to water backup against the foundation & wall. He put rebar in the blocks openings and then filled them with mortar. I am convinced that wall would survive any natural disaster. He also got someone to do the evacuation, addition of a drain pipe and gravel so that it will never happen again.
