“I believe that restoration is not only about the preservation of historic buildings, but the preservation of the craftsmanship that is required to save these significant structures. Walking through the ashes of a burned down 1780s cape, I managed to salvage the only survivor of that intentional fire; hand wrought nails. This was just one of many buildings prior to and since, unable to escape such a fate, and it awakened a passion in me. The possibility of breathing new life into homesteads that continue to exist in our landscape centuries after they were built became my calling. Over 40 years later, with the desire to produce our own entranceways, windows and moldings, with the same focus; first, to preserve history, be architecturally respectful and build windows to last the test of time, and second, to preserve the craft by passing on those skills to the next generation.”
