Our Approach
One contractor accountable for the whole system.
Most security failures happen in the seams between vendors. Sherlock owns the entire lifecycle — layout, equipment, installation, programming, testing, and maintenance — so there's one company responsible when it matters.
We work on new construction and existing buildings alike, including service for major systems originally installed by others. Installations carry a one-year labor and materials warranty, and service contracts keep systems compliant year after year.
