Stone & lime Historic Restoration Services | About Us

About Us


Restoration contractor Stone & Lime has a long track record of working on historic masonry projects spanning from Massachusetts to Texas. Patricia Pelchat and Kenneth Uracius started Stone & Lime Historic Restoration Services in 2004 to supply difficult-to-procure masonry restoration products to the historic preservation community.

As the use of, and demand for, these products increased within the restoration market, Stone & Lime Historic Restoration Services began providing labor services to help execute restoration projects. In 2016, Christopher Dabek joined the Stone & Lime team, bringing his knowledge of masonry restoration and building envelope restoration. In recent years Stone & Lime has been taking the role of general contractor, managing all trades of the projects and working directly with owners such as the National Park Service, the GSA, Harvard University, Bentley University, and Wellesley College among others. A few of the most notable projects are the JW McCormack Federal Courthouse in Boston, the restoration of Fort Jefferson in the Dry Tortugas National Park, and the stabilization of Plymouth Rock.

As Stone & Lime Historic Restoration Services has undertaken more challenging projects as well as managing every aspect of them in recent years, it has consequently expanded its management team with seasoned historic preservation experts to increase its reach and capabilities. This has allowed Stone and Lime to pursuit larger more complex jobs, as well as having the experience and talent to manage subcontractors.

Stone & Lime Historic Restoration Services, true to its origins, has a sister company named Freedom Cement, LLC, which was started to continue to provide historically accurate materials to restoration contractors. In 2010 Freedom Cement resumed production of natural cement from Rosendale, New York. Freedom Cement currently produces natural cement from the Lawrence mine in Rosendale and is supplying mortar to iconic structures such as the Statue of Liberty and the Brooklyn Bridge in NY. Freedom Cement is the only supplier that publicly declares its natural cement rock is mined in Rosendale, NY and has full control of the production and distribution of natural cement from Rosendale, NY.
