Richmond windows

My husband being a contractor sometimes has to go out of state for some special projects. His latest journey took him to a huge old castle home outside of Richmond. His job and his crew were to set up over three hundred sets of scaffolding. At some points four storeys tall. The main contractor on this job were re-mortaring all the stone on the castle. One of the other companies were doing the window replacement from richmond windows. Usually you see white or brown windows. These window frames were an off gray color.
