PORCHES
1. Historic porches on houses in Old North Knoxville should be repaired, or may replicate the original porch if documentation of its size and design can be discovered.
MASONRY
4. Identify and preserve masonry features that define the historic character of the building, including walls, railings, foundations, chimneys, columns and piers, cornice and door and window pediments.
5. Replace an entire masonry feature that is too deteriorated to repair. Use the remaining physical evidence to guide the new work, and match new to old.
6. If historical, pictorial or physical documentation cannot be found about a masonry feature, a modern design sympathetic to the building would be appropriate. A new masonry feature should be compatible in size, scale, material and color.
7.Match replacement mortar to the original mortar in color, composition, profile and depth. If necessary, analyze the original mortar to determine the proportions of lime, sand and cement. A "scrub" technique shall not be used to repoint. The width or joint profile shall not be changed unless the change will return the joint to its original appearance.
8. Never repoint with mortar of high Portland cement content, unless that is the content of the original mortar.
