Heritage Restoration and Design Studio is happy to announce that we are certified to use the JAHN Mortar and the rest of the product line produced by Cathedral Stone, Inc. Cathedral Stone is based out of Maryland, and is an importer of quality masonry products from Europe. “This is another great feather in our cap here at Heritage Restoration. Coupling our past experience with masonry and statuary repair with this new product line will really be of great benefit to our clients,” said Stephen Berlinger project manager at HRD.

What does it mean to be certified by Cathedral Stone?

Cathedral Stone values the uniqueness of its products in the marketplace. As such, only those who have gone through their certification process have access to the company’s full product lines. By becoming certified, HRD now has access to a wide range of products that with great properties for both interior and exterior stone repair.

It is important to note that all of these products are non-epoxy based. This is huge, as they allow for the proper amounts of moisture to enter and leave the stone. Other epoxy and latex abased stone fillers do not allow for moisture to pass through the patch at the same rates as what the actual stone allows for. Overtime these alternative patching methods will fail and create greater damage to the stone. “The cathedral stone certification has expanded my masonry repair abilities passed cement and mortar into the whole stone preservation world,” said Kory Stremlau, shop manager at HRD Studio, ”It has unlocked a brand new approach to the restoration and repair of stone. I am excited to see where this new ability takes Heritage and myself.”

Heritage Restoration now joins the ranks of only a few certified masonry restorers in the central Midwest.

Here is what this product line empowers us to restore:
