In Kind Replacement

Best practices from Historic New England experts

Historic New England strives to retain the historic fabric of the structures and landscape features in our collection through proactive maintenance and conservative repairs and treatments. Some elements, like roofing or siding shingles, are sacrificial layers that need to be replaced as part of a maintenance cycle. Other elements might be subject to decay through inadvertent exposure to weather or even through natural aging processes.

When we need to replace an element, the preferred practice is to replace the material using the same material type or species, dimension, texture, detailing, and compatibility, or shortened commonly to the phrase “replace in kind.” Historic New England recognizes that there may be situations where exact replacement in kind is impractical due to reasons of material durability or of repair location. Our in-kind replacement white papers attempt to identify these issues and the appropriateness of certain replacement materials.
