I searched the archives and came up with nothing. So, this weird question might apply to others, please post any HELPFUL leads.
I am in search of a local company who does environmentally-correct "acid Washing" of a concrete porch. Someone painted it years ago, and it's time I work on the exterior of my home. I could potentially need this contractor to do other concrete work, like add draining holes in a concrete wall, and do a little re-grading of concrete in my back yard. I do not want Power washing, as that would make the existing concrete rough. Any and all help is much appreciated. -- to the power of breathing, Dan Myers Intuitive Masseur 215.901.0899
