Henry Frerk Sons was founded over 140 years ago by the determination and hard work of Henry Frerk, who described himself as a "sawed-off and hammered down German."
March 16: In light of the ongoing COVID-19 emergency we have chosen to cancel the upcoming Dryvit certification class and Keim class. All attendees will be notified directly. Given the uncertainty surrounding the current situation we are unfortunately unable to reschedule the classes at this point. Coming up on February 19 & 20: Our intensive hands-on two-day Jahn Restoration Training Workshops introduce traditional methods of masonry repair using JAHN Restoration Mortars. This includes the repair of limestone, sandstone, terra cotta and brick. The objective of these workshops is to demonstrate materials and techniques to achieve long lasting results. Our classes welcome masons, contractors, craftspeople, specifiers, and other preservation professionals. Architects can receive AIA/CEU credits upon request.
