90 Grove Street, Twin City Glass managed the complete demolition, abatement, and installation of 213 historic aluminum windows. In a successful collaboration with Martin Brothers Construction, converting this structure into mill-style apartments required seamless coordination between the ownership, architect, and General Contractor to meet strict Massachusetts Historical Commission standards. By handling the full scope—from hazardous material abatement to final glazing—we delivered a turnkey solution that preserves the building's industrial heritage while providing modern performance and efficiency for its new residents.
