Ask 4C:

I own a cute little 1920s bungalow. I am looking to make the original windows more energy efficient, and think I may need to replace them. What are my options?

Dear Seattle Bungalow,

Original wood windows on historic buildings are important architectural features – their craftsmanship and unique design often is irreplaceable. What many don’t realize is that the repair and weatherization of existing wood windows can be very practical. The National Park Service offers free technical briefs on repair techniques; Preservation Brief 9 addresses wood windows. Properly maintained and repaired wooden windows will increase energy efficiency, and continue to enhance the historic character of the building. Hope this helps, and good luck!
