This project is a custom built historic window period replication. The original window was decayed beyond any cost effective repair so a new historic replication window was needed to match. The first part of most period replication work is to carefully remove the original and bring it back to the shop for replication. Once they’re the first thing I do is take the sash out, and remove the glass panels that will be reused. The next step is to take careful measurements, including measurements from the field so I have something to verify against while in the wood shop. Once the jamb and sill are taken apart I can measure and match all the components. The next step is to set up the wood working machines required to manufacture all pieces. The sash are made exactly to the original with mortice and tenon joinery, matching profiling and to seat the existing glass panels exactly. The wood is all vertical grain fir and the hardware is either stainless steel or solid brass. No glue was used for this project except at interior trim joints. Oil base primer was used behind some jamb joinery, and behind the hinges for longevity protection. I also made what I call structural storm sash and they are mounted to the prime sash. Once the jamb is made it is fitted in the field and the sash are fitted for operation before the glass is installed. Installation, wall plaster repair, priming and painting were all done by Westbrook. This historic window period replication is an example of quality workmanship found at Westbrook. I use a fully outfitted wood shop with the right machines, and am fully tooled for field work with my custom built utility truck.
