One year after Alston's death in 1977, a group of artists and historians, including the renowned painter and collagist Romare Bearden and art historian Greta Berman, together with administrators from the hospital, and from the NYC Art Commission, examined the murals, and presented a proposal for their restoration to then-mayor Ed Koch. The request was approved, and conservator Alan Farancz set to work in 1979, rescuing the murals from further decay. Many years passed, and the murals began to deteriorate again – especially the Alston works, which continued to suffer effects from the radiators. In 1991 the Municipal Art Society's Adopt-a-Mural program was launched, and the Harlem Hospital murals were chosen for further restoration (Greta Berman. Personal experience). A grant from Alston's sister Rousmaniere Wilson and step-sister Aida Bearden Winters assisted in completing a restoration of the works in 1993. In 2005 Harlem Hospital announced a $2 million project to conserve Alston's murals and three other pieces in the original commissioned project as part of a $225 million hospital expansion.
