Benefits

Cutting-Edge Diagnostic Technology

We troubleshoot today’s issues while preparing your facility for tomorrow. Our technicians deploy thermal imaging, power quality analyzers, and circuit loggers to pinpoint faults and reveal hidden risks. We design repairs that support smart metering, submetering for tenants, and Title 24–compliant networked lighting controls. From surge protection and transient voltage suppression to scalable conduit fill and spare capacity in panels, our fixes anticipate growth—EV charging, new POS stations, added refrigeration, or expanded IT loads—without rework.

Compliance and Safety First

We handle permitting and compliance end to end, aligning with the California Electrical Code (based on NEC), Title 24 energy standards, CALGreen, Glendale Municipal Code, and Glendale Fire Department requirements for life safety interfaces. Our fieldwork adheres to NFPA 70E electrical safety practices, and all equipment is UL-listed and installed per manufacturer specs. We communicate with the City of Glendale Building and Safety Division and Glendale Water & Power to schedule inspections and shutdowns, ensuring a smooth, compliant project.

Expert Troubleshooting Team

Quality repairs start with materials and method. We use copper THHN/THWN‑2 conductors, EMT or rigid galvanized conduit, MC cable where appropriate, and compression fittings for durable terminations. All lugs are torqued to spec, connections are insulated and labeled, and panels are organized to reduce heat and harmonics. We verify integrity with megger tests, thermal imaging, and load balancing, and we replace failing components—breakers, contactors, LED drivers—with top-tier brands that match existing system ratings and listings.

Customized Service Plans

Every Glendale property operates differently. We begin with a fast assessment, then tailor a repair plan around your hours, access constraints, and critical circuits. For restaurants and retailers, we offer early-morning or late-night work; for offices and medical suites, we coordinate phased shutdowns and notification signage. We stage materials, secure lifts for parking lot poles, and prepare hot work permits where required. You get a clear scope, timeline, and cost before we start—no surprises.

Frequently Asked Questions

Do I need a permit in Glendale for electrical troubleshooting and small repairs at my retail space?+

Many like-for-like repairs—replacing a failed breaker, driver, switch, or receptacle—don’t require a permit. However, new circuits, panel replacements, or service upgrades do. We’ll evaluate your specific situation and, if needed, submit to the City of Glendale Building and Safety Division and coordinate inspections to keep your project compliant.

Can you work after hours at The Americana at Brand, Glendale Galleria, or Montrose Shopping Park?+

Yes. We regularly schedule early-morning or late-night repairs to avoid disrupting foot traffic and tenant operations. We coordinate access with property management and security, follow loading dock protocols, and ensure egress lighting remains code-compliant during any temporary shutdowns.

How do Glendale’s hot summers affect electrical systems in commercial buildings?+

High ambient temperatures increase conductor resistance and stress terminations, often revealing loose lugs, weak breakers, and undersized circuits. Rooftop conduits and disconnects experience UV and heat damage. We use thermal imaging to find overheating, balance loads across phases, and tighten/replace components to prevent nuisance trips and failures.

Can you coordinate a temporary shutdown with Glendale Water & Power for a panel repair?+

Absolutely. For work requiring a meter pull or service interruption, we coordinate with Glendale Water & Power to schedule a safe window. We create a shutdown plan, notify affected tenants, perform the repair efficiently, and restore power with post-restart testing and documentation.

Our EV chargers in a mixed-use garage stopped working—can you troubleshoot them?+

Yes. We diagnose power supply issues, contactors, network faults, and cable/connector damage for Level 2 commercial EVSE. We verify upstream breakers, ground fault monitoring, and load management settings, and work with the vendor as needed to restore service and ensure code compliance.
