Outlets & Switches in San Mateo, CA

Experienced Local Electricians

Operating in San Mateo since 2008, we've worked across the city's varied building types, from older homes requiring careful electrical updates to new construction with modern automation systems. This experience informs our approach to every installation.

Transparent Pricing & Detailed Estimates

We provide upfront cost estimates that clearly outline labor, materials, and any additional requirements before work begins. Our pricing reflects the actual complexity of your project, without hidden fees or surprise charges, so you can make informed decisions about your electrical upgrades.

Common Outlet & Switch Issues We Address

Insufficient Outlet Capacity

Modern households use significantly more electronic devices than older electrical systems were designed to support. When you're running extension cords across rooms or stacking power strips to access electricity, your property may lack adequate outlet coverage. So, we strategically add outlets in high-use areas like home offices, kitchens, and entertainment centers.

Outdated Two-Prong Outlets

Ungrounded two-prong outlets found in older homes lack the safety protection that modern appliances require. These outlets can't accommodate three-prong plugs without adapters and provide no ground fault protection.

For those dealing with a home that dates back to the 1960s or even further, updating the entire property can quickly turn into a major financial commitment. That's why we work with homeowners to prioritize critical areas first, like kitchens, bathrooms, and rooms with sensitive electronics. We can also provide a phased upgrade plan that fits your budget while improving safety over time. Our electricians will assess your specific situation and recommend the most cost-effective approach, which might include GFCI protection where full grounding isn't immediately feasible.

Failed GFCI Protection

GFCI outlets don't last forever. They eventually wear out and stop detecting electrical faults, which means you could get a dangerous shock in wet locations.

We check and replace any broken GFCI outlets. We also verify that their protection covers all the required wet areas in your home or building.

Our Professional Services

Standard Outlet Replacement

Worn outlets with loose connections, cracked covers, or poor grounding create shock hazards and damage connected devices. We replace outdated outlets with modern devices featuring:

• Secure connections
• Proper grounding
• Tamper-resistant shutters

USB-Integrated Outlets

Built-in USB ports eliminate bulky adapters while providing dedicated charging for smartphones, tablets, and other devices. We install outlets with USB-A, USB-C, or combination ports positioned at convenient locations throughout your property.

GFCI Outlet Installation

GFCI outlets protect against electrical shock in areas exposed to moisture. We install GFCI outlets in kitchens, bathrooms, garages, outdoor locations, and other areas where water contact is possible, meeting California's strict safety requirements.

AFCI Protection Upgrades

AFCI devices detect dangerous electrical arcing that can cause fires. We install AFCI outlets or breakers in bedrooms, living areas, and other locations required by current electrical codes.

Dimmer Switch Installation

Adjustable lighting controls improve ambiance while reducing energy consumption. We install dimmer switches compatible with LED fixtures, verify proper load ratings, and configure settings for smooth dimming performance.

Smart Switch & Outlet Integration

Connected devices allow remote control, scheduling, and voice activation through smartphone apps or home automation systems. We install smart switches and outlets that integrate with major platforms, program settings, and verify reliable network connectivity.

Additional Outlet Installation

Insufficient outlets force reliance on extension cords and power strips, creating fire hazards and inconvenience. We add new outlets at strategic locations, running wiring through walls or along baseboards while minimizing visible damage to finished surfaces.

Three-Way & Multi-Location Switches

Control lights from multiple locations using properly wired three-way or four-way switch configurations. We troubleshoot existing multi-location setups and install new systems that provide convenient control throughout your property.

Our Installation Process 

Initial Assessment & Requirements Analysis

We evaluate your current outlets and switches, identify safety concerns, and discuss functional needs. This includes testing existing devices, verifying grounding, and noting locations requiring code-compliant upgrades.

Circuit Capacity Verification

Before adding outlets or high-load devices, we calculate existing circuit loads to verify adequate capacity. If circuits are near maximum capacity, we recommend solutions ranging from load redistribution to new circuit installation.

Device Selection & Specifications

Based on your requirements, we present options that include: 

• Standard devices
• USB-integrated outlets
• Dimmer switches
• Smart controls

We explain features, compatibility considerations, and pricing for each option.

Professional Installation

Our electricians do the following: 

• Turn off the power to the affected circuits
• Remove old devices
• Verify proper wiring connections
• Install new outlets or switches

We test each device under load, verify proper grounding, and confirm GFCI/AFCI protection operates correctly.

System Testing & Demonstration

After installation, we test all devices to verify proper operation, check for voltage irregularities, and demonstrate smart device features if applicable. We provide guidance on maintenance and troubleshooting for future reference.

Frequently Asked Questions

How do I know if my outlets need to be replaced?

Signs requiring replacement include: 

• Loose-fitting plugs
• Visible damage or discoloration
• Warm outlet covers
• Buzzing sounds
• Outlets that don't hold plugs securely

Any of these symptoms indicates worn internal components that should be addressed promptly.

In San Mateo, is it mandatory for homes to have tamper-resistant electrical outlets?

Yes, the California electrical code requires tamper-resistant outlets in all residential dwelling areas. These outlets feature spring-loaded shutters that prevent foreign objects from entering slots while allowing standard plug insertion.

Can I replace a standard outlet with a USB outlet myself?

While basic outlet replacement might seem straightforward, improper installation creates fire and shock hazards. We recommend professional installation to verify proper wiring connections, grounding, and code compliance, especially when upgrading to specialized devices.

What's the difference between GFCI and AFCI protection?

GFCI devices protect against ground faults and electrical shock by detecting current imbalances, primarily used in wet locations. AFCI devices protect against arc faults that cause fires, which are required in bedrooms and living areas. Some modern devices combine both types of protection.

How many outlets can be on one circuit?

The National Electrical Code doesn't specify a maximum outlet count per circuit but limits total load capacity. General-use, 15-amp circuits can typically support 8-10 outlets, while 20-amp circuits handle 10-13 outlets, depending on connected device loads and wire gauge.
