Your older frame mouldings could be in great shape. Occasionally we only have to replace glass or fabric and paper mats. Over the years, many chemically unstable materials were used in the picture framing industry (card boards, tapes, and adhesives). We could replace your old acidic mats and tapes with new conservation materials to extend the life of the art and bring it up to today’s preservation framing standards.
