What To Expect During Design, Fit, And Installation

An interior storm window is only as good as its fit.

An experienced interior storm windows company can confirm the cause with a quick inspection.

Installers need to know whether the sash operates, whether the stop molding is original, and whether there is enough depth for the storm frame and the hardware that holds it in place.
