Verified record
International Stone Inc. is a granite, marble and quartz countertop fabricator based in Woburn, Massachusetts, in business since 1995 and offering kitchen and bathroom design work for residential and commercial customers. The company carries a BBB rating of A+ and shows a strong 4.4-star aggregate from 44 Google ratings, though no individual review text is on file describing specific jobs. Local news from 2016 reported the company's approved move into a larger Woburn warehouse to support its stone fabrication operations, and it also appeared on a 2020 list of local businesses that received a Paycheck Protection Program loan. A more serious matter is on the public record: in 2012, OSHA cited International Stone Inc. for multiple serious workplace safety violations — eleven at an Ansonia, Connecticut fabrication operation with proposed penalties near $47,600, plus separate citations tied to the company's Woburn facility. These findings concern worker safety in the shop rather than the quality of finished countertops, but anyone considering the company should be aware of this history. For a straightforward kitchen or bathroom countertop project, the company's decades in business and strong online rating point to an established local fabricator; it is worth asking directly about current shop safety practices given the past OSHA record.
