Whole Home Surge Protection Pages: What Homeowners Actually Need to Read
A homeowner searches surge protection after a storm takes out a refrigerator control board, and lands on a page that says a device will protect every appliance in the house, guaranteed. That claim is wrong, and a page built on it will not convert the careful reader who is ready to pay for the work.
Honest pages convert better in this trade. Surge protective devices have ratings, limits, and a second half to the story that most electrician pages leave out.
Say the two levels out loud
Panel mounted protection, often called Type 1 or Type 2 depending on where it sits relative to the service disconnect, handles large surges entering from the utility side and reduces what reaches branch circuits. Point of use protection at the outlet handles smaller, locally generated spikes and the residual energy the panel device lets through. The National Electrical Code, in Article 242 and the 2020 cycle's Section 230.67 for dwelling services, made surge protection part of the service conversation, which is a concrete fact a page can state instead of a promise it cannot keep.
A page that explains both levels sells both jobs without overselling either. A page that calls the panel device total protection sets up the callback after the next storm.
The panel check is part of the service
State plainly that the visit starts with the panel: available breaker space or a listed connection method, panel age and condition, and grounding electrode condition, because a surge device dumps energy to ground and a poor ground path limits what it can do. Homeowners understand a sequence. First we check, then we install, then we show you the indicator light and what it means when it changes.
That indicator detail matters more than it looks. Many devices have a status light or alarm that signals the protective components have absorbed their limit. Telling the customer on the page, and again in person, to check it after major storms turns a silent failure into a planned replacement.

Profile and page have to agree
Google Business Profile Help is clear that your services list should reflect work you actually do, so add surge protection as a service only when the page behind it exists and says the same thing. Whitespark's Google Business Profile guide makes the same point field by field: the profile sends the click, the page has to close it, and a mismatch between the two is where the call leaks out.
End the page with the real constraints: typical visit length, whether a utility pull is ever needed for your preferred mounting, and what the device warranty covers versus what it excludes. Exclusions stated up front read as confidence in this trade, not weakness.
Frequently asked questions
Does a panel surge protector protect everything in the house?
No. It reduces large surges at the service, but smaller spikes and residual energy can still reach electronics. That is why point of use protection at sensitive equipment is the second level, not an upsell.
How do I know if my surge device is still working?
Most panel devices have a status light or alarm showing the protective components are active. Check it after major storms and during any panel work. If the indicator shows the device has expired, it needs replacement, not a reset.
Does the electrical code require surge protection?
The 2020 National Electrical Code added a requirement for surge protection on dwelling unit services, in Section 230.67, with later cycles keeping the topic in Article 242. Whether it applies to your job depends on your local adoption and the scope of work, which your electrician should confirm.
Why does grounding matter for surge protection?
A surge device works by diverting energy to ground. A corroded, loose, or missing grounding connection limits how much it can divert, so checking the grounding path is part of a proper install, not an extra.
