Electrical Services for Virginia, DC & Maryland
S&H Contracting Unlimited is a licensed and insured electrical contractor serving Northern Virginia, Washington DC, and Maryland. We handle residential and commercial work — from panel upgrades and EV charger installations to emergency repairs and lighting projects. Every job comes with a written estimate before work begins, and we stand behind what we build.
Our Services
Emergency Electrician
Electrical emergencies happen without warning. We respond across Northern Virginia to diagnose and fix the problem — burning smells, dead circuits, panels that won’t reset, storm damage at the service.
Panel Upgrades
Older homes often run on 60–100A panels that were never sized for modern loads. We handle the full upgrade: permit, Dominion Energy coordination, new panel, and inspection — most jobs in a single day.
EV Charger Installation
A Level 2 charger adds 25–30 miles of range per hour instead of the 4–5 from a wall outlet. We confirm panel capacity, run the dedicated 240V circuit, mount and wire the charger, and pull the permit.
Light Fixture Installation
Recessed LED retrofits, chandelier and fixture swaps, ceiling fans on properly rated brace boxes, dimmers and smart switches — mounted to hardware that can hold it, wired to code.
We serve homes and businesses from Alexandria to Stafford — across Prince William County, Fairfax County, and into Washington DC and Maryland.
