Whole House Surge Protector Installation in Baltimore, MD
Most homeowners think about power surges only when lightning strikes. The reality is that the average home experiences power surges more than a dozen times a day, from running the dishwasher, to squirrels chewing on power lines, to fluctuations in the local power grid. Each one sends excess voltage through your home's wiring, quietly wearing down appliances and shortening the life of your electronics.
Whole house surge protector installation from Stella Electric puts a single device between your home's electrical system and everything in it, protecting every outlet, every appliance, and every device connected to your wiring, all at once. We serve homeowners throughout Baltimore, MD and the surrounding area.

Why Homeowners Need Whole Home Surge Protection
Power surges do not have to be dramatic to cause damage. A washing machine will not get fried the way a hard drive does, but repeated exposure to excess voltage causes it to heat up every time wearing down components faster and leading to premature replacement that costs far more than surge protection would have.
The problem is only growing. The country's electrical infrastructure is aging, and deteriorating power grids are a recognized contributor to increased surge frequency in homes. Relying on individual power strips to cover your most valuable electronics is no longer the approach experts recommend. The better solution is to protect the whole home at once.
What a Whole House Surge Protector Actually Protects
A whole home surge protector installs directly at your electrical panel and covers everything downstream. Think of it as an invisible surge protector sitting in front of every outlet in your home.
That means protection for:
Appliances plugged into wall outlets throughout the house
Large appliances on dedicated circuits, including refrigerators, washing machines, and dryers
Devices directly wired into your home's electrical system, such as a garage door opener
Electronics and devices storing digital data, including computers, smart TVs, and home automation systems
A common misconception is that whole house surge protection is only valuable during storms. Surges from everyday causes, a dishwasher cycling, a neighbor's AC unit kicking on, a blip in the local grid, are far more frequent than lightning strikes and just as capable of degrading your appliances over time.
How Much Does Whole House Surge Protector Installation Cost?
The final price depends on:
The size and model of surge protector selected
The specifications of your home's electrical system
Labor for the installation
Stella Electric provides flat-rate quotes before any work begins, no hourly estimates and no surprise charges. Financing is also available if you need it.
Choosing the Right Whole Home Surge Protector
The right surge protector for your home depends on two things: the types of appliances and devices you want protected, and the operating voltage of your home's electrical system. Not every unit is sized the same, and the right match matters for reliable protection.
Surge protectors that consistently rank among the top options for residential installations include the EATON CHSPT2ULTRA, the Siemens FS140, and the Leviton 51120-1. Stella Electric will recommend what is the right fit for your home's specific needs during the installation consultation.

Yes. A whole home surge protector installed at your electrical panel protects every device and appliance in your home including those wired directly into your system, like a garage door opener. They work against surges from any cause, not just lightning strikes, which account for only a small fraction of the surges a typical home experiences.
Yes. Home rewiring is a major electrical project and requires permits in Baltimore, MD. Stella Electric handles the permit process as part of the job, ensuring all work is inspected and meets current electrical code requirements.
The right unit depends on your home's appliances and operating voltage. Models that rank consistently well for residential use include the EATON CHSPT2ULTRA, Siemens FS140, and Leviton 51120-1. A Stella Electric electrician will assess your home and recommend the appropriate unit during the consultation.
For most homeowners it is. A single surge event can damage or destroy expensive appliances and electronics that cost far more to replace than the surge protector itself. When you factor in the protection of every device in the home, not just those on a power strip the cost is relatively modest for the coverage provided.
