The Glass Doctor Advance Measurement System helps commercial customers prepare for when their glass will break, not if their glass might break. The Glass Doctor specialist determines the types of glass in an apartment complex, hotel, office building, retail establishment or other business. Next, the specialist measures the glass that would be needed in case of breakage. The glass types and measurements are kept on file at the Glass Doctor location. If there is a breakage, the customer simply calls the Glass Doctor franchise, explains which glass needs to be replaced, and the glass is ordered immediately. Advance Measurement saves the time of the initial assessment service call and ensures measurement accuracy. Businesses easily can incorporate Advance Measurement into their disaster recovery strategy plans.
