The short answer
How Lightning Harms Wiring
Lightning carries an enormous electrical charge. When it hits your home or a nearby object, that charge can travel through your electrical wiring, often bypassing standard surge protectors. The result can be melted insulation, scorched wires, or a fire hazard hidden inside your walls.
Even if the strike is blocks away, the surge can enter through underground power lines. Your appliances, outlets, and circuit breaker panel may all be at risk. You might notice a burnt smell, flickering lights, or a breaker that will not reset. These signs mean the system needs a professional inspection, not just a reset.
Signs of Surge Damage
After a thunderstorm, check your electrical panel for tripped breakers or scorch marks. Look at outlets for blackening or cracks. Test lights and appliances for odd behavior, like buzzing or dimming. If anything seems off, turn off the main power switch if you can do so safely.
Also watch for a burning plastic or ozone smell near outlets or the panel. That smell can indicate melted wiring. Do not touch exposed wires or attempt repairs yourself. Water damage from the storm can make the situation more dangerous, so keep your distance and call a professional electrician.
- Tripped circuit breakers that will not stay on
- Burnt or melted outlet faces or plugs
- A persistent burning smell near electrical fixtures
- Flickering or dimming lights after the storm
- Electronics that stop working or show error codes
- Power that cuts out in only one room or circuit
Protecting Your Home
A whole-home surge protector installed at your main panel can absorb some of the shock from a lightning strike. Point-of-use surge protectors for expensive electronics add another layer. However, no device fully stops a direct strike, so unplugging sensitive items before a storm is the most reliable step.
If you live in an area with frequent spring thunderstorms, make a habit of unplugging computers, TVs, and other valuables when severe weather is forecast. Also check your home insurance policy to understand what damage is covered. Policies vary, and your insurer decides what is covered.
Water Damage Connection
Lightning can also cause water damage indirectly. A strike can knock out your well pump, leaving your crawl space or utility room vulnerable to flooding. Power surges can also damage your HVAC system, which may leak water onto floors and walls.
If you find standing water or damp drywall after a storm, treat it quickly. Water that sits for more than a day can soak into wood and insulation, creating conditions for mold growth. Local water damage pros can help dry out affected areas and assess what needs replacing.
When to Call the Pros
Do not try to rewire or fix a damaged panel yourself. An electrician should inspect your system and make safe repairs. If you also have water intrusion, you may need two types of help: one for the electrical hazard and one for drying and restoring your home.
For water-soaked walls, floors, or belongings, local water damage pros can remove standing water, dry out materials, and prevent mold from spreading. They can also work alongside an electrician to ensure the area is safe before any cleanup begins. Acting quickly reduces the risk of long-term damage.
Storm season can bring both lightning and heavy rain in the same afternoon. After any severe weather, walk through your home to spot signs of electrical or water trouble. Early attention keeps small problems from growing into major repairs.
- Call an electrician for any burnt wiring or tripped breakers
- Call the pros if you find wet drywall or soaked floors
- Take photos of damage for your insurance records
- Keep a flashlight handy in case the main power goes out
- Do not enter a flooded room with standing water near outlets

Can a nearby lightning strike damage my electronics?
Yes, a strike does not have to hit your house directly. The surge can travel through the ground or utility lines and enter your home. Even a strike a mile away can cause voltage spikes that fry sensitive devices. Unplugging electronics before a storm is the right line of defense.
Will my surge protector stop lightning damage?
Standard power strip surge protectors are often too weak for a lightning surge. A whole-home surge protector installed at your main panel offers more protection, but even it can be overwhelmed by a direct strike. The only sure way is to unplug devices during a storm.
What should I do right after a lightning strike?
First, check for any fire or burning smell and shut off the main power if you can do so safely. Do not touch wet surfaces or electronics. Then call an electrician to inspect your wiring and a water damage pro if you see any wet areas. Document everything for your insurance claim.
