If the walls of historic houses could talk, they might relate stories of mold, broken bricks, cracked foundations and rotten frames imposed on their structure by the passing of time. They’d also likely warn of the unforeseen issues and immense challenges found in restoration projects. On Thursday October 10th, the Pilgrim Hall Speaker Series welcomes Lee McColgan, author of the book A House Restored: The Tragedies and Triumphs of Saving a New England Colonial. In an engaging two-hour presentation, he will share his personal journey – a house restoration project   that changed the course of his life, prompting him to leave his job in finance to become a specialist in historical restoration contracting, preserving historic buildings, houses and properties across all time periods.  His book is a memoir steeped in history, chronicling the painstaking but ultimately rewarding restoration of his 300-year-old South Shore home. The presentation is from 6pm to 8pm at the Pilgrim Hall Museum at 75 Court Street in Plymouth. Tickets are $10 for non-members, $5 for members and free to students with a valid ID.
