We are thrilled to announce the winners of the 2024 Cathedral Stone Excellence in Craftsmanship Award!

Each year, Cathedral Stone representatives keep an eye out for outstanding work in masonry restoration, preservation, and maintenance. Standout projects are submitted by our reps and reviewed by the entire team, including Dennis Rude, Stonecutter and President of Cathedral Stone Products.

For 2024, one project rose above the rest:

Jepol Construction, for their bold, innovative, and highly skilled work repairing the Empire State Building in New York City.

Cathedral Stone Products and Jepol Construction have partnered for many years, united by shared values in restoring and protecting masonry. Preserving the long-term health and integrity of historic structures is at the core of both organizations. Jepol takes restoration to new heights—literally. Their team has developed a comprehensive rope-access system, using specialized gear to safely reach and work on high-rise buildings throughout NYC. It’s no exaggeration to say the Jepol crew is fearless.

Jahn Restoration Mortars have been used on the Empire State Building for decades. In fact, M70 patches applied over 30 years ago are still performing today.

Using these time-tested materials and their innovative techniques, the Jepol team recently repaired spalled limestone areas using Jahn M70 Limestone Repair Mortar. Based on their consistent track record, we have no doubt these new patches will endure just as well.

Please join us in congratulating Jepol Construction—our 2024 winners! It’s inspiring to see craftsmanship of this caliber in our industry.

A big thank you to everyone who participated in this year’s competition. If you’d like to be considered for the 2025 Excellence in Craftsmanship Award, email us at hello@cathedralstone.com with CRAFTSMANSHIP AWARD in the subject line.
