We know that in order to perfectly match the original windows in a

historic building, they have to be made the same way they were originally built.

That's why we use the traditional methods, historic machinery and real wood. 



We use methods that have stood the test of time - like mortise and tenon joinery. It's simple and strong and has been used by woodworkers, stonemasons and blacksmiths for thousands of years because of its proven reliability. 

The surviving millwork in America's historic buildings is a product of 19th century machinery. We use the same machinery because it allows us to match the profiles and characteristics of the original sash and windows as closely as possible. Modern methods simply can't match it. 


Real wood brings warmth and character to your home that can't be replicated by man-made materials. It provides natural longevity that comes with low environmental impact and carbon footprint when compared to other building materials.

Historic homes, churches and buildings that were built hundreds of years ago.

Many of them retain their original splendor because of the wood features and methods with which they were built.
