San Mateo, nestled in the heart of the Peninsula between San Francisco and Silicon Valley, presents unique challenges for electrical systems. The city's diverse housing stock ranges from historic downtown Craftsman homes built in the early 1900s to modern developments in Hillsdale and Bay Meadows, each with distinct electrical demands. Whether you're upgrading a century-old panel in a Central San Mateo bungalow, installing EV charging infrastructure for your Tesla, or adding smart home technology to a Baywood Park residence, selecting the right electrical contractor is critical for safety, code compliance, and long-term reliability.
The San Mateo area's position in California's tech corridor means homeowners often have sophisticated electrical needs—from home office setups requiring dedicated circuits to whole-home automation systems. Combined with California's increasingly stringent energy efficiency requirements and the city's specific building codes, electrical work here requires contractors who stay current with both technology and regulation. Poor electrical work isn't just inconvenient; it poses fire hazards, can void insurance policies, and creates costly problems during home sales when inspections reveal code violations.
This comprehensive guide examines six licensed electrical contractors operating in San Mateo in 2026. We've analyzed their licensing history through the California Contractors State License Board (CSLB), verified insurance coverage, evaluated customer reviews across multiple platforms, and assessed their experience with San Mateo's specific requirements. Our goal is to provide you with data-driven insights that help you make an informed decision based on your specific project needs, whether that's a simple outlet installation, a complete panel upgrade, or complex commercial refrigeration electrical work.

How We Ranked These San Mateo Electrical Contractors
Our evaluation process begins with California Contractors State License Board verification, confirming each contractor holds an active C-10 electrical license in good standing. We verified license numbers, checked for disciplinary actions, and confirmed how long each company has held their license—an indicator of experience and stability. All contractors featured here maintain active licenses and carry the required $25,000 contractor bond, which protects consumers in case of contract breaches or incomplete work.
Insurance verification was our second critical step. We confirmed workers' compensation coverage where applicable and general liability insurance, protecting homeowners from potential liability if workers are injured on their property. Review analysis followed, examining Google and Yelp ratings with attention to both volume and recency of feedback. We read through actual customer comments to identify patterns in service quality, communication, pricing transparency, and technical expertise. A contractor with eight recent five-star reviews provides more reliable data than one with a single review from years ago. We also considered specializations and project types, since electrical contractors often develop expertise in specific areas—residential service work, panel upgrades, commercial refrigeration, or new construction. This multifaceted approach ensures our rankings reflect real-world performance, not just marketing claims.

What to Look for in a San Mateo Electrical Contractor
San Mateo operates under California's Title 24 building standards plus local amendments adopted by the city's Building Division. Any electrical work beyond minor repairs requires permits from the San Mateo Building Department, and contractors must be familiar with local inspection protocols and code enforcement priorities. The city has been particularly focused on electrical safety in older homes, where outdated panels, aluminum wiring, and insufficient grounding create hazards. Your contractor should proactively discuss permit requirements and factor inspection timelines into their project schedule.
Given San Mateo's Mediterranean climate with dry summers, electrical systems must account for fire safety considerations. This includes proper outdoor outlet installation with GFCI protection, landscape lighting that meets clearance requirements, and panel locations that comply with wildfire interface codes if you're in hillside areas. The city's push toward electrification—replacing gas appliances with electric alternatives—means many contractors now regularly handle 240V circuit installations for induction ranges, heat pump water heaters, and HVAC systems.
Insurance verification is non-negotiable. Request certificates of insurance for both general liability and workers' compensation before work begins. Some smaller contractors legally operate without workers' comp if they have no employees, but this should be clearly disclosed. Check references specifically from San Mateo projects, as familiarity with local inspectors and permitting staff can significantly smooth the process. Finally, obtain detailed written estimates that itemize materials, labor, permit fees, and timelines. San Mateo's competitive market means you should compare at least three quotes, but be wary of bids significantly below others—they often indicate shortcuts, unlicensed subcontractors, or poor-quality materials that will cost more long-term.

Fuata Electric
License #906539 • San Mateo, CA
18 years licensed
Workers' Comp ✓
$25,000 bond
Active License ✓
3.7
6 reviews
Fuata Electric operates under license #906539, active for 18 years, positioning them as an established mid-sized contractor in San Mateo. With full workers' compensation and bonding, they maintain proper insurance for their team. Their 3.7-star Google rating across six reviews presents a mixed picture that warrants careful consideration. Owner Dave has earned strong praise from satisfied customers, with one noting they've worked with Fuata for five years both personally and through client recommendations, praising prompt service, fair pricing, and efficiency.
Recent positive reviews from December 2025 highlight quick project completion and friendly service attitudes. One customer praised their technician's diagnostic skills in solving a complex doorbell circuit problem left by previous electricians. However, negative reviews raise concerns about follow-through and workmanship quality. One January 2026 review complained about lights improperly timed after timer replacement and work violating National Electrical Code. An August 2025 review described waiting 1.5 months for a promised quote after an hour-long consultation. These mixed signals suggest Fuata Electric may deliver excellent service with certain technicians or project types while struggling with consistency. They may be best suited for smaller projects where Dave himself is involved, or for customers willing to closely monitor project progress and workmanship. Contact them at (650) 513-1492 or through fuataelectric.com, but request detailed timelines and specifications in writing.

Air Temp
License #889684 • San Mateo, CA
19 years licensed
Workers' Comp ✓
$25,000 bond
Active License ✓
4.3
7 reviews
Air Temp holds license #889684, active for 19 years, and maintains full workers' compensation coverage and bonding. Their 4.3-star Google rating across seven reviews reflects generally positive customer experiences with some notable exceptions. The company appears to specialize in refrigeration and HVAC work with electrical components, differentiating them from pure electrical contractors. One review specifically praised them as "Refrigeration Repair pros" for fixing a commercial refrigerator in time for business reopening, indicating commercial expertise alongside residential services.
Recent reviews from January 2026 and May 2024 show ongoing operations with technician Luis receiving specific praise for availability, reliability, and competitive pricing on Peninsula electrical and HVAC work. Multiple reviewers describe prompt service and professionalism. However, a February 2021 complaint about a van driver damaging a parked car suggests occasional lapses in professionalism or employee training. For San Mateo homeowners needing electrical work related to heating, cooling, or refrigeration systems—such as installing dedicated circuits for HVAC equipment, commercial kitchen electrical, or troubleshooting appliance electrical issues—Air Temp's cross-discipline expertise could prove valuable. Their 19 years in business demonstrates staying power. Reach them at (650) 591-1004 or airtempco.com. They appear best for projects requiring both electrical and HVAC knowledge, though primarily residential service customers should verify their specific electrical project fits the company's expertise.

Maloney Electric
License #728713 • San Mateo, CA
29 years licensed
No Workers' Comp
$25,000 bond
Active License ✓
5.0
1 reviews
Maloney Electric has maintained California contractor license #728713 for an impressive 29 years, demonstrating long-term stability in the San Mateo electrical contracting market. They carry the required $25,000 bond but currently operate without workers' compensation coverage, typical of very small operations or sole proprietors without employees. Their single 5-star Google review provides limited data for comprehensive assessment, though the perfect rating is encouraging.
The lack of substantial online presence—no website listed and minimal review history—suggests Maloney Electric may operate primarily through referrals and repeat customers rather than active marketing. This traditional business model isn't inherently negative; many skilled tradespeople maintain full schedules through word-of-mouth recommendations without investing in digital marketing. Nearly three decades of continuous licensing indicates they've successfully navigated California's regulatory requirements, economic cycles, and evolving electrical codes. For San Mateo homeowners, Maloney Electric may represent a low-overhead option potentially offering competitive pricing on straightforward electrical work. However, the limited online information means due diligence is especially important—request multiple references from recent San Mateo projects, verify current insurance coverage, and obtain detailed written estimates. Contact them at (650) 347-7211. They may be best suited for customers prioritizing experience and local knowledge over extensive digital reviews, willing to do additional vetting work.

JD Electric
License #1128782 • San Mateo, CA
1 years licensed
No Workers' Comp
$25,000 bond
Active License ✓
5.0
3 reviews
JD Electric is the newest contractor in this comparison, having obtained license #1128782 just one year ago. Despite their recent licensing, they've earned a perfect 5-star rating across three Google reviews, indicating early success in building customer satisfaction. They maintain the required $25,000 contractor bond but currently operate without workers' compensation, suggesting a small startup operation, possibly a sole proprietor or owner-operator model.
The limited review history includes feedback from October 2024 praising knowledgeable and quality work, plus an earlier February 2019 review recommending their excellent service. The gap between reviews may indicate the business operated under different circumstances before formal licensing, or reviews attributed to the owner's previous work experience. With only one year of licensed operation, JD Electric hasn't yet built the track record of longer-established competitors, but their perfect rating suggests they're delivering quality work to early customers. The absence of a listed website indicates a bare-bones operation focused on work rather than marketing, which could mean lower overhead and competitive pricing.
For San Mateo homeowners, JD Electric represents a calculated choice—newer contractors often provide attentive service and competitive rates while building their reputation, but lack the extensive experience of 20 or 40-year veterans. They may be well-suited for straightforward residential electrical projects where lower pricing is important and the homeowner is comfortable with a newer business. Contact them at (650) 703-5457. Request detailed references and ensure all agreements are thoroughly documented in writing.

How We Rank Contractors
Licensing & Insurance
Active CSLB license, workers' comp coverage, and bond amounts verified.
Experience
Years of licensed operation in California, demonstrating longevity.
Customer Reviews
Google & Yelp ratings weighted for consistent positive feedback over time.
Priority Score
Our algorithm combines all factors into a single score, updated regularly.
Our ranking methodology for San Mateo electrical contractors combines multiple data sources to provide a comprehensive assessment of each company's qualifications, reliability, and customer satisfaction. The process begins with California Contractors State License Board (CSLB) verification, where we confirm active license status, check disciplinary history, and determine years of continuous licensing. The CSLB database provides transparency into each contractor's legal standing, bond status, and any complaints or enforcement actions. Longer licensing periods generally indicate greater experience navigating California's regulatory environment and adapting to evolving electrical codes, though newer contractors shouldn't be automatically discounted if they demonstrate other strengths.
Insurance verification forms our second pillar. We confirm workers' compensation coverage where required and verify the mandatory $25,000 contractor bond. California law allows contractors without employees to operate without workers' comp, but this should be disclosed to customers who may prefer the additional protection. We then analyze online reviews from Google and Yelp, examining both quantitative ratings and qualitative feedback. Review volume matters—eight recent reviews provide more statistical reliability than a single review, even if both show five stars. We assess review recency, since feedback from 2026 and 2025 better reflects current operations than reviews from 2015.
Qualitative review analysis involves reading actual customer comments to identify patterns in communication, workmanship quality, pricing transparency, and problem resolution. We note specific project types mentioned to understand each contractor's specializations. Finally, we consider practical factors like website presence, phone accessibility, and responsiveness to inquiries. Our goal isn't to crown a single "best" contractor, since the ideal choice varies by project type, budget, and homeowner priorities. Instead, we provide the data homeowners need to make informed decisions based on their specific circumstances, whether they prioritize decades of experience, perfect recent ratings, specialized expertise, or competitive pricing from newer entrants.

Frequently Asked Questions
How much does electrical work cost in San Mateo?
Electrical costs in San Mateo typically run 15-25% higher than California averages due to the Peninsula's elevated cost of living and competitive labor market. Simple service calls for troubleshooting or minor repairs generally range from $150-$300, with hourly rates for licensed electricians between $95-$175. Panel upgrades, common in San Mateo's older housing stock, typically cost $2,500-$5,000 depending on amperage increases and whether the main service requires upgrading. Installing a 240V circuit for EV charging runs $800-$2,000 depending on distance from the panel and whether trenching is required for garage installations. Whole-house rewiring in older San Mateo homes averages $8,000-$15,000 for a typical single-family residence. Always obtain written estimates from at least three licensed contractors, ensuring quotes include permit fees, materials specifications, and timeline expectations. San Mateo Building Department permit fees add several hundred dollars to most projects but are legally required and protect you with proper inspections.
Do I need a permit for electrical work in San Mateo?
Yes, virtually all electrical work in San Mateo beyond replacing existing switches, outlets, or light fixtures requires permits from the San Mateo Building Division. This includes adding new circuits, panel upgrades, service increases, outdoor wiring, and any work involving new electrical boxes or conduit. Permits ensure work meets California Title 24 standards and local amendments, and they require inspections that verify safe installation. Your contractor should handle permit applications, though you as the property owner are ultimately responsible. Permit fees typically range from $200-$600 depending on project scope. Unpermitted electrical work can create serious problems when selling your home, as inspection contingencies often reveal code violations. Insurance companies may deny claims for fires originating from unpermitted electrical modifications. The San Mateo Building Division is located at 330 W. 20th Avenue, and their website provides permit application information and fee schedules.
What should I ask an electrical contractor before hiring?
Start by requesting their C-10 electrical license number and verify it yourself through the CSLB website at cslb.ca.gov. Ask how long they've been licensed and whether they've worked on similar projects in San Mateo specifically. Request proof of current general liability insurance and workers' compensation coverage, obtaining actual certificates rather than verbal assurances. Inquire about their permitting process—will they handle applications and scheduling inspections, and are permit fees included in their estimate or additional? Ask for a detailed written estimate itemizing materials, labor, permits, and timeline, including start and completion dates.
Request at least three recent references from San Mateo projects similar to yours, then actually call those references to ask about communication, cleanup, adherence to estimates, and problem-solving when unexpected issues arose. Ask whether they guarantee their work and for how long, and what happens if inspection reveals code violations requiring corrections. Inquire about their approach to protecting your home during work—will they use drop cloths, how do they handle dust from cutting into walls, and what's their cleanup process? Finally, ask about payment schedules. California law limits deposits to $1,000 or 10% of contract price, whichever is less, for projects under $5,000. Be wary of contractors requesting large upfront payments.

How do I verify a contractor's license in California?
Visit the California Contractors State License Board website at cslb.ca.gov and use their "License Search" tool. You can search by license number, business name, or contractor name. The results show license status (active, expired, or suspended), issue date, bond information, and workers' compensation status. Critically, the profile reveals disciplinary actions, citations, and complaints filed against the contractor. Review the "Complaints/Actions" section carefully—while a single resolved complaint over 20 years may be acceptable, multiple recent actions suggest problems. Verify the license classification shows C-10 for electrical work. The CSLB also provides license verification by phone at 800-321-CSLB (2752). Always verify licenses yourself rather than trusting a contractor's word, as some operate with expired or suspended licenses hoping customers won't check. This simple five-minute verification protects you from unlicensed operators and reveals red flags before you sign contracts.
What's the best time of year for electrical work in San Mateo?
San Mateo's moderate Mediterranean climate allows electrical work year-round without the extreme weather constraints affecting other regions. However, scheduling considerations still apply. Fall (September-November) and spring (March-May) often offer the best combination of contractor availability and comfortable working conditions. Summer months can see increased demand as homeowners tackle improvement projects, potentially leading to longer waits for appointments and higher pricing. Winter (December-February) sees San Mateo's rainfall, which can complicate outdoor electrical work, service upgrades requiring temporary power disconnection, or projects requiring open trenching for underground wiring.
For interior work like panel upgrades, rewiring, or adding circuits, timing matters less climatically but consider your own schedule—these projects may require temporary power interruptions lasting several hours. If you're planning solar installation, EV charger installation, or outdoor lighting projects, spring and fall provide optimal conditions. Many contractors offer more flexible scheduling in January and February when demand drops post-holidays. Regardless of season, book established contractors at least 2-4 weeks in advance for planned projects, though emergency service calls typically receive same-day or next-day response.

Selecting an electrical contractor in San Mateo requires balancing multiple factors: experience and licensing history, insurance coverage, customer satisfaction data, project-specific expertise, and communication quality. The six contractors profiled here represent the spectrum of options available to San Mateo homeowners in 2026, from Dannels Electric's four decades of experience to JD Electric's newer operation building its reputation. First Stage Electric's consistent five-star ratings across multiple recent reviews demonstrate the quality achievable from mid-career contractors, while Fuata Electric's mixed feedback reminds us that even established companies can have inconsistent performance requiring careful vetting.
No single contractor is universally "best" for all situations. Your ideal choice depends on your specific project—a simple outlet addition might suit a newer contractor offering competitive rates, while a whole-house rewire in a 1920s San Mateo Craftsman benefits from decades of experience with legacy systems. The data we've compiled provides the foundation for informed decision-making, but your due diligence shouldn't stop here. Verify licenses through the CSLB, request current insurance certificates, call references from similar San Mateo projects, and obtain multiple written estimates before committing.
Compare Local Pros exists to streamline this research process, providing verified contractor data and real customer experiences in one accessible location. Use our comparison tools to evaluate contractors side-by-side, examining their licensing longevity, review patterns, and specializations. Remember that the lowest bid isn't always the best value—factor in experience, communication quality, and insurance protection. Quality electrical work protects your family's safety, preserves your home's value, and provides peace of mind that your systems meet California's rigorous codes. Take time to choose carefully, and don't hesitate to request detailed information from contractors before making your final decision.
