What We Do for Homeowners

From panel upgrades and rewiring to EV chargers and heat pumps, we handle every electrical need in your home.

Panel Upgrades & Replacements

Modernize your electrical panel to safely handle today's power demands.

An outdated or undersized electrical panel is one of the most common — and most serious — hazards in older homes. We replace fuse boxes and aging panels with modern circuit breaker panels rated for today's appliances, EV chargers, and home additions. We handle all permitting and inspections.

  • 100A, 200A, and 400A service upgrades
  • Fuse box to circuit breaker conversions
  • Sub-panel installation for additions or garages
  • Full permitting and town inspection coordination

Home Rewiring

Full or partial rewiring to replace outdated or unsafe wiring throughout your home.

Knob-and-tube wiring, aluminum wiring, and deteriorated insulation are fire hazards that need to be addressed. We perform full and partial rewiring projects with minimal disruption to your home, bringing everything up to current code.

  • Knob-and-tube wiring removal and replacement
  • Aluminum wiring remediation
  • Partial rewiring for renovations and additions
  • Code compliance and inspection-ready work

Outlet & Circuit Installation

Add new outlets, USB ports, GFCI protection, and dedicated circuits anywhere in your home.

Whether you need more outlets in a remodeled kitchen, GFCI protection in bathrooms and garages, or a dedicated circuit for a new appliance, we handle all outlet and circuit work cleanly and to code.

  • Standard and GFCI outlet installation
  • USB and USB-C outlet upgrades
  • Dedicated circuits for appliances and equipment
  • Outdoor and weatherproof outlet installation

Lighting Installation & Upgrades

Interior and exterior lighting installation, recessed lighting, and fixture upgrades.

From recessed lighting and under-cabinet lights to landscape lighting and security floodlights, we install and upgrade lighting throughout your home. We also handle dimmer switches, smart lighting controls, and ceiling fan installations.

  • Recessed and can lighting installation
  • Ceiling fan and fixture installation
  • Dimmer and smart switch upgrades
  • Exterior, landscape, and security lighting

EV Charger Installation

Level 2 home EV charger installation for all major electric vehicle brands.

Charge your electric vehicle overnight at home with a Level 2 charger. We assess your panel capacity, run the necessary wiring, and install a hardwired or plug-in charger in your garage or driveway — fully permitted and inspected.

  • Level 2 (240V) charger installation
  • Compatible with Tesla, Ford, GM, Rivian, and all major brands
  • Panel capacity assessment included
  • Hardwired and plug-in NEMA 14-50 options

Electrical Safety Inspections

Comprehensive inspections to identify hazards before they become dangerous problems.

Whether you're buying a home, selling a home, or just want peace of mind, our safety inspections cover your entire electrical system — panel, wiring, outlets, grounding, and more. You'll receive a detailed written report of any findings.

  • Full-home electrical system assessment
  • Panel and wiring condition evaluation
  • GFCI and AFCI protection check
  • Written report with prioritized findings

Smoke & CO Detector Installation

Hardwired smoke and carbon monoxide detector installation and replacement.

Hardwired detectors are more reliable than battery-only units and are required by Massachusetts code in most residential applications. We install interconnected smoke and CO detectors throughout your home so all alarms sound together.

  • Hardwired interconnected smoke detectors
  • Carbon monoxide detector installation
  • Combination smoke/CO units available
  • MA code compliance for all installations

Generator Installs & Hookups

Full standby generator installation and transfer switch hookups for whole-home backup power.

Never be left in the dark during a New England storm. We handle the complete electrical side of standby generator installations — from sizing the transfer switch and running the wiring to coordinating permits and inspections. We also wire portable generator hookup circuits for a safe, code-compliant connection.

  • Whole-home standby generator electrical installation
  • Automatic and manual transfer switch installation
  • Portable generator hookup circuits (NEMA inlet)
  • Load calculation and panel coordination
  • Full permitting and town inspection

Heat Pump Installation

Full mini-split and whole-home heat pump installation — equipment, wiring, and startup.

We supply and install mini-split and central heat pump systems from start to finish — no separate HVAC contractor needed. That includes mounting the indoor and outdoor units, running refrigerant lines, installing the dedicated 240V circuit and disconnect, and commissioning the system. We also install heat pump water heaters as a drop-in replacement for your existing tank.

  • Mini-split and multi-zone system installation
  • Central heat pump system installation
  • Heat pump water heater installation
  • Dedicated 240V circuit and weatherproof disconnect
