Whole-House Surge Protection
SPARKWISE ELECTRICAL INC
The Damage You Never See Coming
Most people picture a surge as a lightning strike. Lightning is the dramatic version and it is not the common one. The everyday version is small, repeated and invisible: the well pump kicking in, the air conditioner starting, a Duke Energy switching event two streets away, a neighbor's equipment cycling. Each one sends a spike down the line that your electronics absorb.
They do not fail that day. They fail eight months later, and nobody connects the two events.
A house in 2026 has more sensitive electronics in the walls than most people realize. Heat pump control boards. Induction ranges. Well pumps. LED drivers in every fixture. Garage door openers. A car charger. Every one of them has a circuit board in it, and every one of them is on the same service as everything else.

What a Whole-House Protector Actually Stops
A panel-mounted protector sits at the service entrance, so everything downstream is behind it: the heat pump and air handler boards, the well pump controller, the induction range, the LED drivers in every fixture, the garage door opener, the EV charging equipment, the smart thermostat, and anything hardwired that you cannot plug into a strip. It takes the big hit from utility switching, nearby lightning, large motors starting in the house and a neighbor's equipment on the shared transformer.

Why the Power Strip Is Not Enough
A good strip at the desk protects what is plugged into it and nothing else. It cannot protect the hardwired equipment, and it cannot stop a surge that arrives on the service before it reaches the room. The two work together: the panel device takes the large surge, the strip takes what is left. Anyone who tells you one replaces the other is overselling.

How a Surge Protector Install Goes
01
We look at the panel first: A surge protector needs two breaker spaces and a short, straight run to the bus. If the panel is full, we tell you before we quote, not after.
02
We size it to the service: A 200 amp residential service and a 100 amp service want different devices. We fit what the panel actually needs.
03
Fitted at the panel, not at the outlet: The device goes on the main panel so everything downstream is behind it, including the circuits you cannot plug a strip into.
04
Permit and inspection where required: In Zebulon, Wendell, Knightdale and Rolesville that goes through Wake County Permits and Inspections. We pull it and meet the inspector.
05
We show you the indicator: Every protector has a status light that tells you it is still working. We show you where it is and what it looks like when the device has done its job and needs replacing.

Frequently Asked Questions
Does a whole-house protector replace my power strips?
No, and anyone who tells you it does is overselling. The panel device takes the big hit; a good strip at the desk takes what is left. They work together.
How long does one last?
Until it has absorbed its rated energy, which could be two years or fifteen depending on what your line throws at it. That is what the status light is for.
Will it stop lightning?
A direct strike on the house is beyond any protector. Everything short of that, which is the overwhelming majority of surge damage, is what it is for.
Do I need two breaker spaces free?
Yes. If your panel is full we will tell you what that means before you commit to anything.
Does it need a permit?
In most of the jurisdictions we serve, yes. It is included in our price and we handle it.

What It Costs
Whole-house surge protection fitted on its own runs $289 to $589, depending on the device and whether the panel has room for it. It is already included at no extra charge with every 200 amp panel replacement we do, which is one of the reasons a panel replacement with us is a single number rather than a base price plus a list of extras. These figures are estimates from jobs we have done, and the exact price for your house comes from a free on-site estimate, in writing, before any work starts.
