Residential Construction

Residential construction is fraught with challenges and full of surprises. Homeowners change their minds, specs change, timetables change. You need a distributor who will be with you from the initial bid to installing smart home systems, to dropping off the keys.

In addition to lighting, Dominion Electric can supply all the electrical products you need to finish your home, from basic and designer wall plates to smart home systems that control lighting and monitors home energy usage in real time, for a safer and more efficient home.

Residential construction is also full of opportunities. We can also help you with backup power generators, electric vehicle charging stations, and photovoltaic (PV) systems including solar panels and batteries for storing excess PV-generated power.

With an inventory of more than $26 million, 250 brands, and 1,000 vendors, we can get you the parts you need, when and where you need them, and at the right price.

Our fleet of 34 vans, trucks and flatbed delivery vehicles leave every weekday morning between 4 and 6 a.m. to deliver product throughout the D.C.–Maryland-Virginia area. Or you can stop by one of our 10 counters or 3 showroom locations on your way to the office or jobsite.
