What we do best

Three things homeowners call us for most

We handle every kind of residential electrical work, but these are the projects we know inside and out.

Kitchen with recessed lighting and under-cabinet lights

Lighting design & installation

Recessed, pendant, under-cabinet and exterior lighting planned around how you use each room, then installed cleanly and on code.

Lighting services

Standby generators

Keep the heat, well pump and fridge running when the power goes out. Generator hookups with manual or automatic transfer switches.

Generator installation

Panel & service upgrades

More capacity for a remodel, an addition, a generator or an EV charger. We replace outdated panels and upgrade service safely.

Lighting is the finish people notice

The right light makes the whole remodel

New cabinets and counters deserve better than a single ceiling fixture. We work with you, your builder or your designer to place every light where it does the most good.

  • Recessed lighting laid out for even, glare-free light
  • Pendants and chandeliers hung at the right height and centered on the work
  • Under-cabinet task lighting for kitchens
  • Dimmers, switching and controls that make sense
  • Exterior, landscape and flood lighting
