How do I fix half my house losing power?

Work through it in order: check the circuit breakers and reset any that tripped, reset your GFCI outlets, look for an overloaded circuit, then check the main breaker. Also rule out a utility outage by checking if neighbors are affected. If none of that restores power, call a licensed electrician.

When is half the house losing power an emergency?

Treat it as urgent if you notice a burning smell, scorch marks, buzzing or popping, a warm panel, sparks or smoke, or a breaker that trips again the instant you reset it. Stop troubleshooting and call a professional right away, since a damaged service drop or failing meter base can escalate quickly.

Can a tripped GFCI outlet cause half my house to lose power?

Yes. A single tripped GFCI outlet can cut power to several other outlets downstream of it, sometimes in a different room. Pressing the reset button on each GFCI outlet in bathrooms, kitchens, garages, and outdoors resolves many partial outages.

Is it safe to reset my main breaker myself?

If you are comfortable, you can flip the main breaker fully off and back on once. If it will not hold, if you feel unsure at any point, or if you notice any burning smell, heat, or noise, stop and call a licensed electrician. Never force a breaker that keeps tripping.

Why Does Only Half the House Go Dark?

Your home is fed by two main power lines, and the circuits are split between them. When one of those lines, one main breaker leg, or a shared circuit fails, everything on that half goes dark while the other half keeps working. That split is your biggest clue. It usually points to a tripped breaker, a tripped safety outlet, or in more serious cases a problem at your panel or the incoming service. Here is how to find it, safely and in order.

Check Your Circuit Breakers First

This is the most common cause and the easiest fix. Find your electrical panel in the basement, garage, or a utility closet. Look for any breaker that has flipped to the off position or is stuck in the middle. To reset it, push it fully to off, then firmly back to on. If power returns, a simple overload was the culprit.

Reset Your GFCI Outlets

These are the outlets with test and reset buttons, found in bathrooms, kitchens, garages, and outdoors. One tripped GFCI outlet can cut power to several others down the line, even in a different room. Press the reset button firmly on each one. This catches a surprising number of partial outages.

Look for an Overload

Did the power drop the moment you switched on a space heater, microwave, or hair dryer? That points to an overloaded circuit. Unplug the heavy items from the affected area, spread them across different circuits, and reset the breaker. If it holds, you found the problem.

Check the Main Breaker

The large breaker at the top of your panel controls power to the whole home. If it has partially tripped, it can knock out large sections. If you are comfortable, flip it fully off and back on once. If it will not hold, or you feel unsure at any point, stop here and call a professional. Do not force it.

Rule Out the Utility

Look outside. Are your neighbors dark too? Was there just a storm? A downed line or a utility side fault can cause a partial outage that has nothing to do with your wiring. If the issue is on the grid, contact Dominion Energy. If only your home is affected, the problem is inside, and it is time for step six.

Still Out? Call a Licensed Electrician.

If none of the above brings the power back, the cause is deeper, often in your home wiring or your electrical panel. These are not safe to guess at. Our Master Electrician will find the real fault and fix it right. Call 703.225.8222.

⚠️ A Few Safety Rules

Never touch exposed wires, and never attempt a repair you are not fully confident in. Electricity does not give second chances. If a breaker keeps tripping right after you reset it, that is the system protecting you from a real fault, not a nuisance to override. And once power is restored, a surge protector helps shield your electronics from the jolt that can come when power snaps back on.
