Our restoration process brings new life into your old windows. This allows us to salvage whatever elements are still viable and add small parts to create more longevity.

If the original sash (operable portion of the window) have been removed and replaced, that replacement will fail more quickly over time. When replacement windows fail, the only option is to replace again. Fortunately the "replace cycle" can be broken, with our custom made replacement sash which can allow for restoration of the original aesthetic of the windows.

Many people think they are stuck with an old, dirty, dingy door or need to upgrade with a cheap, hollow door option, and this couldn't be farther from the truth! Our door restoration process can create a welcome upgraded curb appeal. We've even won a Preservation Award for a door on Irving Pl!

Wood Options
We have access to nearly any wood species to match or repair existing windows/doors for custom jobs. What we have stocked, and is most used, is Forest Stewardship Council (FSC) Certified Select Grade Eastern White Pine (right photo), native to the Western New York area. The photo on the left is "Sinker Cypress", found on river beds, from the 1800's. As lumber companies from over a century ago would send logs down the river, some would sink, those are now collected and harvested to create replicas or replace original elements.


Glass Options
One of the core elements of updating original windows (especially 100year old + windows) is the ability to have the same aesthetic with modern heat saving technology with new types of glass. While retrofitting an existing window with insulated glass can be difficult, laminated glass is a nice option. Laminated glass provides more insulating qualities, as well as sound deadening. Adding a laminated glass storm window is another option to add even more thermal and sound protection. For our new sash, insulated glass is used, and glazed with special silicone to look like a traditional putty-glazed window.
