Our Work



Benefits
Smart, future-ready repairs
We use advanced diagnostics—thermal imaging, circuit tracers, load monitoring, and insulation resistance testing—to pinpoint issues without guesswork. When repairs are made, we recommend scalable upgrades: whole-home surge protection (critical for foothill power fluctuations), smart breakers or monitoring modules, and circuits sized for future EV chargers, heat pumps, or backup generators. We specify copper conductors, AFCI/GFCI protection where required, and modern, Wi‑Fi–ready devices when requested, so your system adapts easily as your needs grow.
Permits and compliance
Shaffer Construction navigates LA County permitting and inspections, coordinating directly with the Department of Public Works Building and Safety Division. We build to the 2022 California Electrical Code (based on NEC), Title 24, fire hazard zone requirements, and local amendments, and ensure utility clearances for meter/panel work. From GFCI/AFCI upgrades to service equipment repairs, we document our work, label circuits, and provide as-built notes so inspections pass cleanly and your home remains fully compliant.
Pro-grade materials, methods
We use spec‑grade devices (Leviton/Hubbell), copper THHN/THWN‑2 conductors, torque to manufacturer specs, and apply anti‑oxidant compounds on aluminum service conductors. In fire hazard zones, we use fire-rated materials and proper clearances. Every connection is verified with proper pigtails, secure terminations, and box fill compliance. We test polarity, grounding, and GFCI/AFCI function before leaving—aiming for reliability you won’t have to think about.
Diagnosis-first planning
Every call begins with a focused interview of symptoms, then a targeted site assessment. We map circuits, isolate fault conditions, and prioritize fixes by safety and impact. You’ll receive options—immediate repair, code-corrective upgrades, or future-ready enhancements—along with pricing and timelines. For complex faults (intermittent trips, shared-neutral issues, voltage drop on long runs), we stage testing to minimize disruption and only open walls or ceilings when diagnostics justify it.
What We Offer
Frequently Asked Questions
My breakers trip when the well pump and dryer run together. Is this a wiring problem or an overloaded circuit?+
Often it’s an overloaded circuit on older 15/20A runs in properties with well pumps and high-draw appliances. We confirm by measuring load and evaluating circuit sharing. If wiring and terminations are sound, we can re-balance loads, add a dedicated circuit for the well pump, or upgrade the breaker where appropriate. If we find heat-damaged conductors or loose neutrals, we repair those immediately and may recommend a panel evaluation.
Are Federal Pacific or Zinsco panels common in Altadena, and should I replace mine?+
Yes, both brands appear in 1960s–1980s homes throughout Altadena. They’re known for breaker performance issues and can be fire hazards. We can maintain them short-term (tightening, labeling, replacing weak breakers), but we strongly recommend panel upgrades for safety and reliability—especially in fire hazard zones or if you’re adding an EV charger. We handle the LA County permit and inspection and can complete most replacements in a day once permitted.
Do I need special electrical requirements for Very High Fire Hazard Severity Zones?+
Yes. Properties in fire hazard zones require fire-rated materials, proper clearances from combustibles, and defensible space considerations for outdoor circuits and equipment. We ensure all repairs and upgrades meet these requirements and coordinate with LA County Building and Safety to verify compliance during inspections.
How long do permits take for electrical repairs in Altadena, and do I always need one?+
Many minor repairs (like-for-like device swaps) don’t need a permit. New circuits, panel work, and substantial rewiring do. LA County Building and Safety typically processes permits within 2–4 weeks. We file the paperwork, schedule inspections, and meet the inspector on-site so your project stays on track with minimal disruption.
