McCormack Building Supply To Reopen Original Location This Summer It has been a rough couple of years for the crew at McCormack Building Supply in Winslow. In October of 2019, they suffered a devastating fire. No one was injured in the blaze, which tore through the business and caused so much smoke that it could be seen from downtown Augusta. Thanks to the help of the community, the business quickly got back on its feet. Within a few days, they were operating from a spot next to Pleau's Market. In fact, they never really "closed". The fire occurred on Friday, October 11th. They were open for business on Monday, October 14th.
