Late last year we finished up a large window restoration project at the Louden Machinery Factory in Fairfield Iowa. Louden manufactured and sold farming equipment, including Barn plans, all over the Midwest between 1868 and 1956. The factory had previously been converted to housing, and received a major makeover last year as part of the work we were doing. About a third of the windows were restored, mostly on the first floor.

We go all out when we're working out of town. Conveniently, the best time to work on a commercial job is usually after 3:30 anyway. More photos of this job to come.
