Denalect Alarm was founded in 1969 by Rod Uffindell as a part-time business while he attended college. The business continued to grow from a part-time to a full-time business and, to date, Denalect has installed over 9000 alarm systems. We are proud of the fact that most have resulted from customer referrals. Denalect Alarm is a local, independent company serving the Northern California counties of Contra Costa, Alameda and parts of Solano county. Our office in Walnut Creek houses all company operations, which include: design, sales, installation, service, monitoring and business operations.
