Window and door treatments that are better for your home…
and the environment.

When windows stop functioning or lose their beauty, it's common for  homeowners turn to replacement windows—many of which are constructed from vinyl or other less sustainable materials. At Sashwright, we believe the most sustainable window treatment is one that is lovingly restored or rebuilt from wood. That's one of the reasons why we specialize in wood windows for historic homes. We want to give you beautiful window and door treatments that look amazing, offer energy efficiency, and rely on sustainable materials.



We pride ourselves on providing the finest high-performance window products for your home.


What our customers have to say about us.

We love our windows. Thank you for all your advice and pointing us to the Marvin windows. And then for installing them for us. I know this wasn't your usual project since you refurbish vintage windows, and a tiny project for you, but you were extremely conscientious and helpful all the way throughout the project. And the windows --now installed -- look wonderful. Without my bidding my husband said he thought noise was cut down with the new windows. He also said he was thinking that they would look nice aesthetically but he was surprised how much better they looked and how they opened up the living room making it feel larger. I work from home, so I spend a majority of my time in my house and Stephen and his team helped make it an even better space to be.

I hired Stephen Colvin and his crew to repair sash cords, and make and install storm windows for 12 wood windows on our house. The work was planned in the summer and completed by end of the the year following the time course initially projected. An email notice provided advance notice of each stage. The team that arrived was always punctual, and the work was performed with efficiency and great care. Interior areas were well covered in advance and cleaned after each work day. The crew are knowledgeable about wood frame windows and enjoy in their work.

I've worked with Stephen a couple of times now to do custom wood storm windows to enhance energy efficiency, reduce draftiness, and protect some intricate old leaded glass windows. Our experience with Stephen was excellent. He is a skilled craftsman and was always extremely professional. Highly recommended!
