Prompt and Reliable

I am a realtor and often rely on electricians to check on and install smoke alarms prior to inspections or to make repairs to properties before they are listed.

Dave is always prompt and reliable and on one occasion went in and fixed a bungled smoke alarm installation by another electrician. He saved the day!


Dave Petersen is a fully licensed and insured electrician who has been in business for over 9 years serving Wareham, Rochester, Marion, Mattapoisett, Bourne and the South Coast area.

Some of the services I offer include generator installation, new construction and remodeling, phone, cable, internet and alarm systems, speaker wiring, panel changes, outdoor flood lighting and service upgrades. more
