WALTHAM, Maine — Two months after putting its 100-acre mill complex in Hancock up for sale, Robbins Lumber has sold it to Elliott Jordan & Sons, a general contractor, for the list price of $2.5 million. The buyer doesn’t necessarily plan to use it as a mill. “We see it as a site that probably has more value being developed over a number of years,” Duane Jordan. Waltham is about 20 miles from the Hancock site; both are in Hancock County. The company, one of the top three Eastern white pine producers in New England, acquired the Hancock sawmill and a Sanford facility from Pleasant River Lumber Co. in 2023. Company President Jim Robbins previously said, shortly after the company bought the Hancock plant, it experienced a major failure of a specialized machine responsible for 60% of the plant’s production.
