Henry Frerk Sons offers our popular classes on historic lime mortar, stone and terra cotta repair, and historic brickwork during the fall and winter. We are continuing to add to our class schedule for Fall 2017, so please join our email mailing list in order to get updates.





Henry Frerk Sons is pleased to announce our upcoming 2017-2018 Masonry Workshop Schedule. Most of our classes are free, but space is limited so register early to secure your spot. All classes take place at our Chicago workshop, which is located at 3210 N. Troy St., directly north of our main facility at 3135 W. Belmont.
