The service
What whole-home surge protection is, what a visit covers and where the line is.
The short answer
A whole-home surge protective device (SPD) is wired into your main panel on its own breaker and diverts voltage spikes to ground before they reach outlets, appliances and electronics. Whole-Home Surge Protection in Danville is booked through pros who cover its 2 ZIP codes, in neighborhoods such as Blackhawk, Diablo, and Greenbrook. In Danville, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. The licensed electrician you choose sets the price and the warranty for the device install.

What shapes a whole-home surge protection job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
Choosing a surge protective device
Devices differ in where they mount, how much energy they handle and what they report. Your panel and your equipment decide what makes sense. Tap an option to compare, then add your pick to your job notes.
What is not part of whole-home surge protection
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Panel replacement, fuse box replacement and wiring repair, which are listed as Electrical Panel Upgrade & Rewiring.
- Any surge device job that reaches $1,000 in labor and materials goes to a licensed contractor. Panel-level work is always done by pros who hold the electrical license.
- Lightning rods and a lightning protection system for the structure, which is specialist work.
- Replacement of equipment already damaged by a past surge.
- Utility service work on the meter, transformer or overhead lines, which belongs to the utility.
License and permits for whole-home surge protection
A whole-home surge protective device is wired into the main panel, so it is licensed electrical work. The pro who takes this job holds the license and works inside the panel with proper safety procedures.
Adding a device at the panel can need a permit and an inspection in some places, and the inspector checks the breaker, lead length and grounding. Your pro tells you whether a permit applies and handles it.
Check the pro license on the profile before you book, and ask for the device model and the permit record if one was pulled. Keep them with your home records and your warranty.

Before you book whole-home surge protection
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph the panel
Take a picture of the closed panel, the label on the door and the inside with the cover removed by the pro. It tells the pro whether there is a free slot and what type of panel you have.
Note past damage
List appliances or electronics that failed after a storm or power event. It guides the device rating and any extra protection.
Check insurance and warranty terms
Some manufacturers and insurers ask for surge protection or offer connected-equipment coverage. Read the terms before you choose a device.
Keep point-of-use protectors for sensitive gear
A panel device does not replace good protectors on computers, TVs and audio. Keep them plugged into rated strips.
Learn the indicator lights
Ask the pro to show you what the healthy and failed lights look like, and add a calendar reminder to check them after storms.
Combine with other electrical work
If you are adding a circuit, charger or panel work, install the device in the same visit so the panel is opened once.
Say where in Danville you are
Add your neighborhood, for example Blackhawk, Diablo, and Greenbrook, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.
