Question Answers

My Alhambra home has old aluminum wiring, which I've heard can be a fire hazard. Can you help make it safer?

Yes, absolutely. This is a common concern in many older homes in our area. We specialize in evaluating and remedying aluminum wiring systems to mitigate fire risks. Our services can include installing proper connectors (CO/ALR devices) at outlets and switches or, for a comprehensive solution, performing a partial or complete house rewiring with modern copper wiring. We'll provide a clear assessment and recommend the most effective and cost-efficient approach to ensure your home's electrical system is safe and up to current standards.

What does a full electrical panel upgrade involve, and when would my home in Alhambra need one?

A panel upgrade involves replacing your home's main electrical service panel and meter to increase its capacity and safety. Homes in Alhambra often need this upgrade when adding major appliances, renovating, or if the existing panel is outdated (like a fuse box) or overloaded, causing frequent breaker trips. Our process includes obtaining necessary permits, installing a new, higher-amperage panel with modern circuit breakers, and ensuring your entire system is properly grounded. As a licensed electrical contractor since 1983, we handle this complex work efficiently, bringing your home's power up to modern demands.

As a family-owned business, what kind of electrical projects have you handled in the San Gabriel Valley?

Since my father started the company in 1983, we've built a deep history of projects across the San Gabriel Valley. Our work ranges from routine residential repairs and lighting installations to comprehensive commercial builds and industrial motor control systems. We've performed countless panel upgrades and house rewires in the area's classic homes, installed backup generators for local businesses, and handled everything from Victorian-style lighting to modern smart home integrations. Our progression from a one-man operation to a multi-licensed team means we have the expertise to manage projects of any scale, all backed by decades of local, community-focused service.
