Professional Type 1, Type 2 & combined surge protection installed by licensed electricians. Properly grounded and verified with written quotes.
Same-day & next-day service available in most areas
A whole-house surge protector clamps voltage at the panel. When the line voltage spikes above a defined threshold, the device diverts the excess current to ground before it propagates downstream.
It does not replace plug-in surge strips — those handle smaller spikes. It handles the big ones: lightning-induced surges, utility switching events, and large appliance kickbacks.

Highest protection level. Ideal for lightning-prone areas, homes with previous surge damage, or heavy electronic loads.

We provide a written quote before any work begins. The price is final unless hidden issues are discovered and you approve changes.
Other installers in Cedarburg often install whatever is on the truck, skip grounding verification, and don't perform post-install testing.
We check grounding first, use vetted reliable devices, and confirm everything works before leaving.
"Lost a TV and a fridge in a single storm last year. Got Grant's to install a whole-house unit afterward. Six months later, another bad storm — nothing in the house even flickered."
"I asked three companies for quotes. Grant's was middle-priced but the only one who actually checked my panel and grounding before quoting."
"Had a Type 2 unit installed. The tech walked me through what it would and wouldn't protect. No oversell, no scare tactics."
No device protects from everything. A whole-house unit handles large external surges. Layer with quality plug-in protectors for sensitive electronics.
Quality units have indicator lights. Most last 5 to 10 years in typical Cedarburg conditions. Replace when the light goes off.
Often the install reduces premiums. We provide documentation that supports claims.
No. The device installs at the main panel. Licensed electrician required. Most manufacturer warranties require professional installation.
The device will likely sacrifice itself but will significantly reduce damage to downstream equipment.
A short call will tell you exactly which tier fits your home, what it will cost, and whether your panel is ready. Get clarity and peace of mind today.
