woods, shall be protected from the elements and decay by painting
or other protective covering or treatment. Peeling, flaking and chipped
paint shall be eliminated and surfaces repainted. All siding and masonry
joints as well as those between the building envelop and the perimeter
of windows, doors and skylights shall be maintained weather-resistant
