Protect Your Milwaukee Home From Outdated Electrical Systems
Many houses built from 1880-1940 across Milwaukee and Waukesha Counties still have outdated electrical systems. These old wiring methods weren’t made for today’s electronics and appliances.

Plus, many insurance companies now refuse coverage for homes with these systems or charge much higher rates. Our local team has upgraded electrical systems in hundreds of Milwaukee area homes – from Bay View to Brookfield. We know how to bring modern safety standards to your home while protecting its historic features and architectural details.
