After a number of frustrating local phone calls to enquire about having window screens made to measure, it was recommended I call Stittsville Glass on Main Street, Stittsville. I did so and had a most pleasant conversation with a gentleman who asked me to bring in my current screens. He thought he could repair them although they were quite bowed, but it might save me the cost of new builds. He did indeed get them into shape very quickly .... at absolutely no charge! Wonderful service, thoroughly recommended.
