About Us

Thank you for taking time out of your busy day to browse our website. Custom Interior Shutters is a factory-direct business, specializing in custom-made window shutters for residential houses and commercial buildings. It is locally owned by William Ketterman and is located in El Cajon, California. We have been serving the greater San Diego, Imperial and Riverside Counties for the last 21 years at the same location. Custom Interior Shutters manufactures custom wood window shutters.

Why wood shutters and not composite or vinyl ?

Three reasons, beautifully hand crafted wood louvers add a warm, appealing appearance to every room because of their furniture grade appearance. They act as insulators to help balance the room temperature and, most of all, it is a product that Custom Interior Shutters can stand behind and guarantee. That is why we are the " Home of Quality and Service " in the window shutter manufacturing business. You don't have to sacrifice quality and service just to have an affordable window dressing at a very competitive price.

Do you have an idea for your next project and need help designing it ?
