When I renovated my old house I had the 1890s windows refurbished. To accomplish this, a carpenter cut the windows in half, replaced the glass with double pane glass and laminated it back together. I had new sash weights fabricated to compensate for the added weight. This was definitely more expensive than a rip and replace, but we were able to save about 90% of the original woodwork. Sills were replaced with synthetic because it was the best way to prevent water intrusion.
