Masonry Workshops

Henry Frerk Sons offers a range of masonry workshops throughout the fall and winter. Most of our classes are offered on Wednesday mornings, and most are free. In addition to classroom learning we offer plenty of opportunities for hands-on practice so you can try out the materials and techniques that we cover.


Can't make our classes? We also do evening presentations several times a year for the Historic Chicago Bungalow Association, so check their seminar schedule to see if there's an upcoming event that works with your schedule!





We are currently scheduling classes for the 2018-2019 Workshop Schedule, and will add sessions as they are confirmed. 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.
