Hi all have been asked to clean a new build as I have not done this before am struggling to quote can someone point me in the right direction. I have done a test patch and site manager is happy, but want quote by end of day. The area is around 140 sq m they want all bricks cleaned including chimney stacks with brick acid if needed then all of the stone work.. site will be level so will use towers. I was thinking of a price around 1600 is that way to much or too little. Just need rough price guide , or per sq m . Thanks Paolo
