Commercial Electrician in Catonsville, MD

When your business needs electrical work, you want a licensed electrician who understands commercial spaces and shows up ready to work. JJ Palmer Electrical Service is led by a Maryland Statewide Master Electrician (#12441) who started his career as a commercial electrician at Alexander Electric in 1978. Today we bring that same experience to business owners and property managers across Catonsville, Ellicott City, Columbia, and Baltimore and Howard County.
