First developed in Holland by Mr. Heinz Jahn, these mortars were scientifically engineered to match the physical properties of the substrate in terms of elasticity, and porosity, as well as tensile and compressive strength. Since then, the company has used its scientific approach to masonry restoration to develop and further refine a full spectrum of completely integrated and compatible..

Whether you need to color match for a mortar repair or color match for the application of a paint/coating, our “pizza box” of color samples is the perfect solution.
Yes, you can get a custom color match, but there is a pretty good chance that the color you need is a color available in our Standard or Premium lines (or even a combination of Standard and Premium colors).
What’s the benefit of matching to Standard and Premium Colors?

Choosing a Standard or Premium color is faster and less expensive. We stock our Standard and Premium colors, which means these will ship out in ..read more

Neela Wickremesinghe (in safety-green), a specialist in architectural and historical conservation at Green-Wood Cemetery
We always know it’s going to be a fascinating project when we hear from Neela Wickremesinghe, a specialist in architectural and historical conservation. She’s the on-site conservator at Green-Wood Cemetery in Brooklyn, NY. Neela fascinates me; she’s part renegade archeologist, digging up chunks of history, and part restoration/preservation artist putting those pieces back together.
Green-Wood is a National Historic Landmark, known just as much for its 478 acres of roll ..read more

We believe that there are two critical elements to world-class masonry restoration work: compatibility and craftsmanship. Our Jahn Masonry Restoration Systems are the most compatible masonry repair products available, and our substrate-specific mortars require proper installation to achieve the performance and longevity that’s synonymous with the Cathedral Stone and Jahn names.
When our founder, Dennis Rude, initiated the Jahn Mortars Certification requirement in the mid 1980’s, the certification course was three days. In 2018, in an attempt to help our busy customers get certified faster, we ..read more

The tendency of Tuckahoe marble to “sugar”
Tuckahoe marble was first quarried in Tuckahoe, New York—just north of Manhattan. Due to this proximity, you’ll see lots of Tuckahoe marble in Manhattan. The greatest challenge of Tuckahoe marble is its tendency to delaminate into a powder — also known as sugaring.
I’m regularly asked if this type of stone can be restored successfully. My response starts with a question: was a consolidant used on past repairs? Consolidants trap moisture and cause rapid deterioration of the substrate from the inside. It is difficult to impossible to repair extre ..read more

Retirement is a bittersweet event. Especially when it’s someone who is both good at her job and fun to work with. That’s Sharon Henn to Cathedral Stone.
Sharon oversees our Accounts Payable division and her sharp eye for those thousands of tiny details that keep things in order is matched only by her dedication in chasing down our owner to get the one task he hates doing, done. Signing checks.
Sharon is retiring at the end of the year. She’s worked hard and she’s looking forward to relaxing on a cross-country trip she’s been planning with her significant other, Bill.
We’re all going to miss be ..read more

When I’m asked about our Bio-Cleaner, I usually respond: imagine the leading biological stain cleaner and add our Light Duty Masonry Cleaner—that’s our Bio-Cleaner. It’s works great on stone, brick, terra cotta facades and concrete structures and walkways and is especially good on grave markers and statues.
Most of the time we need more than just the biological stain removed; we need a general masonry cleaner to complete the job. This is a one and done product, and it’s one of my go-tos on structures that show even a hint of biological staining. It’s great in removing those stains and for peri ..read more

A wise decision was made to expose the various stone types and colors for their aesthetic and historical value, and not use whitewash stain.
In 1883, Thomas Osborne built the St. George Residence, known today as Hotel 17, located in lower Manhattan. Not only was Osborne a developer and architect, he was also the owner of the stoneworks that supplied the stone for the building. Earlier this year, a facade restoration for the building kicked off. That’s where the discovery begins.
Epstein Engineering called on Cathedral Stone early in the restoration project, beginning with the building’s first ..read more
