Been asked to quote a clean of a brick building, and was wondering if there was any recommended methods.
We've cleaned plenty of walls, cladding, fascias etc over the years, however, a full building worries me a little.
Have used pressure washers with no chemicals or heat previously and walls have come up fine, just worried about the pointing, and quality of finish. as its a fairly high profile building, and we get a lot of work from these clients.
