Specialized masons committed to conserving our architectural heritage through the application of traditional materials

Historic Stone Cleaning

Founder of Preservation Works Ltd., Rob Wozniak, demonstrates the ThermaTech cleaning system by removing 100+ years of carbon deposits while preserving the stone’s natural patina & avoiding an over-cleaned or a sandblasted look.

Our Products

We use & sell high-quality, specialty masonry products that have been used for thousands of years in traditional building & are now being used in modern “green” construction due to their high quality, reasonable cost & minor environmental impact.  We offer traditional binders imported from Europe at competitive prices.

Visit to Tigre in Spain

We love Tigre Natural Hydraulic Limes and Natural Cements, and you will too! We wanted to see with our own eyes where these products come from and how they’re made, so we traveled to Spain to meet the 3rd generation of the family that has been producing and selling these high-quality materials since 1945.
