Woodharbor Doors and Cabinetry officials in Mason City are going back to their roots as they have completed negotiations to buy the former Fieldstone Cabinetry building in Northwood and bring 150 jobs back to Worth County. Curtis Lewerke and his brothers Dennis and Jonathon were the former founders of Fieldstone back in 1981, selling the business to Masco Corporation in 1986. Masco closed the Fieldstone facility in the mid-90s. Curtis Lewerke says it’s the most aggressive expansion in the company’s history in machinery, technology, equipment and training. Lewerke says Woodharbor will move its interior door line from the Mason City facility to Northwood and expand their kitchen and bathroom cabinet line in their Mason City facility. Lewerke says the additional machinery and manufacturing space will accommodate Woodharbor’s projected growth plans through the year 2008. He says employment at Northwood is expected to grow to 120 while the Mason City plant employment will stay steady. Lewerke pointed out that the expansion was contributing to the fight against terrorism as it improves people’s lives and the communities. Current employment at the Mason City facility is about 400 people. With the acquisition of the Northwood plant, the total combined square footage of administration and manufacturing space will total around 380-thousand square feet.
