Whole-Home Surge Protection · Virginia
A whole-home surge protective device (SPD) mounts at the panel and limits voltage spikes before they reach your circuits. The current National Electrical Code requires one for new and replaced services in dwellings; it works best paired with plug-in protectors for electronics.
Coastal storms in Hampton Roads and older Richmond homes shape repair and upgrade work.
Across the Mid-Atlantic, homes deal with humid summers, coastal storms and occasional ice. Permit offices, utilities and housing stock differ by city, which affects how whole-home surge protection is planned and scheduled. These local guides cover the Virginia cities where we have written specific notes.

Summer thunderstorms roll across Arlington from the Blue Ridge most afternoons in July and August, and lightning strikes near the Potomac can send spikes through the power, cable and fiber lines that feed every house. Arlington has an unusually high share of home offices, so surges often take out laptops, monitors and network gear along with heat pump boards and smart thermostats.
