Restoring and preserving historical buildings can be done in an environmentally friendly way without sacrificing the integrity of the project.  One company, Cathedral Stone Products, strives to update its environmentally safe masonry restoration product line on a consistent basis.

Some of the more well-known projects that Cathedral Stone Products has worked on include the Statue of Liberty, Terminal A at Reagan National Airport, the White House, the U.S. Naval Academy and the U.S. Military Academy at West Point.

Several of the nation's historic universities have also worked with Cathedral Stone on their restoration projects including Notre Dame University, Harvard University and Yale University.

Green restoration projects, like those that use Cathedral Stone Products, are becoming more popular.  Popular enough that commercial insurance companies have taken notice and now many offer policies tailored towards these unique restorations. 

One company, Fireman's Fund, started this new trend when it created its green building policy in 2006, Green-Gard.  This new product offering from Fireman's Fund was the only insurance company recognized in the Environmental Defense Fund's Innovations Review 2008.
