"You can stop searching for an electrician - hire Brey Electric. You couldn?t ask for a more professional contractor. He installed a GFCI outlet in the bathroom and had to go through a very tight attic space. He recommended the attic route because it would be less expensive than running a wire up from the basement. He explained clearly what the job would entail, finished the job ahead of schedule, vacuumed the floor when the job was completed, and went a step further to offer to provide a custom extension cord if the toilet seat cord isn?t long enough. Conner takes customer service seriously and works with the electrical contractors association to stay current with industry practices. He?s relaxed and very easy to work with. I won?t hesitate to refer Brey Electric to my friends and call on Connor for future jobs."

"Boy Scout Service: trustworthy, helpful, friendly, courteous, kind, etc. Installed 50A outlet. Since he was here I had him look at some other work to bid on (remove baseboard heater and install outlet). He moved his schedule around and got it done the same day, going out of his way to save me money. I'll be calling Cornerstone in the future!"

"The job entailed replacing receptacles on both sides of the kitchen sink; GFCI protecting as needed; replacing a receptable on the exterior, cutting a switch on the interior above it to control it. The serviceman arrived on time, was courteous, and finished the job in less than an hour. Although the repairs were expensive, the total cost was as quoted. And I was able to use my MasterCard to pay for it. The serviceman also cleaned up nicely after the job was done."

FAQs for electrical wiring or panel upgrade projects in Sherwood, WI

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
