TSW Electric in Alpine holds California C-10 Electrical Contractor License #832000 and has operated from its Otto Avenue base since the company's 2005 incorporation, serving residential and commercial projects across East County. Whole-home electrical upgrades run in parallel with HVAC system replacements coordinated by Maximum Comfort Heating and AC Repair on Alpine Blvd, where 240-volt circuit provisioning and disconnect-switch installation must precede condenser commissioning. Service calls cover main panel upgrades to 200-amp capacity, subpanel additions, dedicated circuit installation for EV chargers, and code-correction work on older Alpine homes built before current Title 24 standards. New-construction scopes include rough-in wiring, fixture trim-out, and low-voltage structured cabling for data and security systems. Underground utility trenching for detached structures requires shared-trench coordination with plumbing contractors such as Alpine Plumbing & Backhoe Inc on Alpine Blvd, where combined excavation runs reduce site disruption and backfill costs. Highest-demand residential projects involve full rewiring of pre-1970s homes, replacing original aluminum branch circuits with copper conductors terminated at AFCI/GFCI-protected breaker positions.
