Licensed Electricians in
Potomac, MD

AJ Long Electric serves Potomac. Our family-owned company has been in business since 1996. Send the property address and work description so our team can review scope, access and availability.

Permit requirements depend on the property jurisdiction, building and electrical scope. The written proposal should identify required permit and inspection coordination. The local authority controls review, corrections and final approval; a mailing city alone may not identify the correct office.

We accept requests for Potomac and nearby areas, including Potomac Village, Potomac Falls, Avenel. Provide your complete address and access details; staff confirm the next step and available visit window after reviewing the request.

For urgent electrical hazards in Potomac, call (571) 444-6886. During business hours, we prioritize safety-related calls and confirm the available response window with you. If you see fire or an immediate threat to life, call 911 first.

Describe the desired change or symptom, provide the equipment model if known, and include photos taken safely with covers closed. Note access restrictions, prior renovations and other loads you plan to add. A home’s age or neighborhood alone does not establish its wiring condition or need for an upgrade.

Estimates are free, with no fee for the visit or the written price. For a panel upgrade, EV charger installation, whole-house rewiring, or another project, request an appointment so we can document the property-specific scope.

AJ Long Electric is a licensed and insured electrical contractor for work in Maryland. John Long is the company founder and Master Electrician, and the company maintains the licenses required for its work. You can verify our credentials before authorizing your Potomac project.
