Every project in Ontario starts with a thorough inspection of accessible attic, crawlspace and wall wiring. We document what is active, what is abandoned, and where connections show heat damage. From there we build a phased plan that replaces the risky wiring first and keeps your family's routine intact.
Aluminum wiring does not always require full replacement. In many Ontario homes, correctly installed connectors at every device and junction bring the system to a safe condition at lower cost. We explain both routes honestly. Homeowners in Guasti, Montclair and Rancho Cucamonga and across San Bernardino County have relied on that straight advice.
