251 WEST 89TH STREET
With an aging PTAC system, the building at 58 West 58th went forward with the replacement of its existing units. Upon replacement, each apartment received a new unit sleeve and a unit with newly installed waterproofing and surrounding insulation to ensure the apartment units remain at optimal temperature for the owner. With the new units installed, a new exterior grille was also installed to give a refined look to the exterior facade.
