Compatibility is the Key Stone

Avoid Premature Failure

Much of the maintenance and restoration of masonry buildings fail prematurely. There are many reasons why: inappropriate materials, poor craftsmanship, or perceived savings. There is a better method; for less money and without the headaches.

When undertaking the important task of historic restoration or maintenance, it is critical to take into consideration the total cost of ownership; comprising material cost, labor cost and durability of the restoration, while not contributing to further deterioration. Choosing inappropriate materials or contractor in the interests of keeping costs down often leads to just the opposite - higher total cost of ownership due to failure from either the materials, the contractor, or both.

Cathedral Stone Products, Inc. is dedicated to providing the appropriate materials to qualified and dedicated restoration professionals. Our materials have been thoroughly evaluated and tested to ensure that they are truly physically compatible with the structure to which they are being applied.

True compatibility means that the repairs will behave in the same manner as the structure, in essence becoming one. The repairs will expand and contract with the masonry, and will be breathable enough to allow water vapor and liquid water to escape to the surface. Therefore, the repair will not fail due to freeze/thaw cycles or salt re-crystallization.

Cathedral Stone Products introduced the first masonry training program in the restoration trade in 1984, and has trained thousands of craftspeople in the proper application and finishing techniques of masonry around the world . As important to a project as using appropriate materials is the use of a qualified craftsman. Craftsmen should be dedicated and specifically trained in historic restoration and maintenance - there is no compromise.
