We just finished some facade work and have gotten several complaints about dirty windows. The contractor did protect the windows while work was happening, and they told us they would leave everything clean, but it looks like there was some dust kicked up around the windows that were adjacent to the sidewalk shed.

Now the scaffolding has been removed and management is uninterested in pushing the contractor to perform cleaning, stating that there is nothing in the AIA contract that specifically requires they clean windows. Do most buildings just hire an outside service to clean up after construction work?
