What Does an Electrical Inspection Actually Cover?

Licensed Electricians | Certified Inspectors

Hi, I am Peter, the Master Electrician at PRO Electric plus HVAC. People usually call me for an electrical inspection at one of a few moments: they are buying or selling, they just had some damage, they are about to add a big load, or they have an older home that has simply never been checked. Whatever brought you here, let me tell you what a real inspection covers and what we tend to find.

An inspection is a professional review of your whole electrical system to catch safety issues, code problems, and parts that are worn or outdated. The goal is a clear picture, not a sales pitch.

What we actually check

A thorough inspection looks at the whole system, not just the outlets you can see. That means the main panel and service, the breakers and their connections, grounding and bonding, the wiring through the home, outlets and switches, GFCI and AFCI protection, light fixtures, and the smoke and carbon monoxide detectors. We confirm everything is installed safely, works as intended, and meets current code, then write up anything that falls short.

When you need one

What we tend to find in older homes

Across our counties, the same issues come up again and again in older homes: outdated or undersized panels, Federal Pacific and Zinsco panels that should be replaced, missing GFCI or AFCI protection, two-prong ungrounded outlets, double tapped breakers, aluminum branch wiring, knob-and-tube wiring in pre-1972 homes, and signs of past overheating or do it yourself work that does not meet code. None of it is unusual, and all of it is fixable. You can see the bigger picture in the warning signs of a failing electrical system.

What happens after

You get a report listing what we found and what needs attention, with the safety priorities called out. From there we can handle the code corrections, pull any permits, and bring the flagged items up to standard. Working detectors are part of that picture too, which is why I always check smoke and carbon monoxide detectors on every visit. For a sale, that report and the corrections that follow are often what keeps the deal moving.

Frequently asked questions

What does an electrical inspection cover?

It covers the main panel and service, breakers and connections, grounding and bonding, wiring throughout the home, outlets and switches, GFCI and AFCI protection, light fixtures, and smoke and carbon monoxide detectors. We confirm each part is safe, works correctly, and meets current code, then document anything that needs attention.

When should I get one?

Common times are buying or selling a home, after fire, flood, or lightning damage, before adding a large load such as an EV charger or a panel upgrade, and for any older home that has never been inspected. If you are unsure about your wiring, an inspection is how you find out.

How long does it take?

A typical home inspection takes a couple of hours, though larger or older homes with more to review take longer. The point is a complete picture, so a careful inspector spends the time at the panel, the outlets, and through the wiring rather than rushing.

What do you find most often in older homes here?

Outdated panels, missing GFCI or AFCI protection, ungrounded two-prong outlets, double tapped breakers, aluminum wiring, knob-and-tube wiring in pre-1972 homes, and signs of past overheating. These are common in older Northern Virginia homes and can all be corrected by a licensed electrician.

Do I need one before selling?

It is not always required, but a pre listing inspection is worth it. You find and fix problems before they surface in the buyer inspection, which keeps electrical issues from becoming a last minute negotiation, and it gives buyers confidence that the system is safe and up to date.
