Welcome to Keystone Sign Service

Keystone Sign Service is a full-service sign company that was started by Douglas Bradley in 1987, and remains family owned and operated. What began as a small business in the basement of the Bradley household quickly grew into a successful company with a 6,000 square foot building, that houses both a manufacturing facility with large metal fabrication equipment and a fleet of service vehicles; as well as a graphics workshop with large format printers. Keystone Sign Service is dedicated to fostering long term relationships with their clients through providing quality products.
