The conservation of the wooden windows at the Lyman Estate began last week, kicking off the slate of 2011 projects set to increase energy efficiency in the 1793 mansion. Most of the window sash date to approximately 1917, when the last major renovation of the mansion was commissioned by the Lyman family. This renovation transformed the exterior of the house from the Victorian look of the 1880s to its current Colonial Revival form.
Improved energy efficiency does not necessarily require replacement of historic windows. While the sash are not quite a century old, they easily have more than another hundred years of life in them. Simple maintenance involves replacing broken glass, some minor joint repairs, new glazing putty, and re-establishing the protective layer of paint. These are basic tasks that most homeowners can undertake on their own with a little time and patience.
During this phase of conservation work, Historic New England is committed to sharing what we learn about caring for old windows. As our team removed the first twenty-eight sash, questions arose regarding the form and function of the previous generation of windows. As work continues and we discover explanations, we plan to share our knowledge and shed light on earlier building technology in the What’s New section of our website.
Although the Lyman Estate function rentals operation is on a brief hiatus during this project, we are currently booking events for April 2012 or later. The grounds and the historic Lyman Estate Greenhouse remain open throughout the year.
