Original window hardware on the National Academy of Sciences building was reconditioned.


At the National Academy of Sciences, masonry requiring a patch repair was filled using a special repair mortar that is compatible with marble. Larger cracks were grouted using injection ports and filled at the surface with the repair mortar.


Prior to installation, the subcontractor color- matched the mortar to be identical to the weathered appearance of the National Academy of Sciences’ stone.
