Built on Experience, Driven by Trust

Electrical USA began with a simple idea in 1986: to deliver reliable, honest electrical services that customers could truly depend on. Founded by Owner Dennis Diller, what started with one man’s hard work as a helper and apprentice soon grew into a locally trusted team serving homes and businesses across Parkton, MD, and Baltimore County, MD.

With over 38 years of experience in the electrical industry, we’ve built our reputation by doing the job right, every time. Our founder started this business from the ground up, learning every aspect of electrical work firsthand before opening Electrical USA. That experience, combined with a hands-on approach to every project, ensures that every customer receives quality workmanship and genuine care.

We’re proud to be a small, local team that values precision, safety, and professionalism. When you choose us, you don’t get a call center or a rotating crew; you get the owner himself, along with two skilled electricians who take pride in every project. We treat your home or business as if it were our own, making sure everything we install or repair is safe, compliant, and built to last.

At Electrical USA, we serve both residential and commercial customers with integrity, offering dependable solutions from generator installations to full system upgrades. We’ve earned the trust of our community by focusing on what matters most: honest work, fair prices, and reliable power for every customer.
