Cornerstone Electrical Systems

Cornerstone Electrical Systems is an electrical contractor that handles generator installs, service upgrades and repairs, remodel wiring, and custom lighting and audio work for homes and businesses. The company is a certified Kohler dealer, so generator work includes manual transfer and automatic standby systems, with sizing, installation, repair and startup.

The company was opened in February 2016 by Andrew and Michelle Galarneau, with Andrew bringing more than 15 years of field experience and Michelle handling customer questions and scheduling. Estimates for generator work are free and done in the home, and the company says it aims to respond to requests the same business day. The office is in East Granby, and the company also takes calls for storm damage and flickering lights.
