 Trustindex verifies that the original source of the review is Google. I have been using Four Star for all of my electrical needs since 2014 and I cannot say enough good things about them.

I have done several remodeling jobs since then and Curt Julian has been my electrician through all of them from big to small.  He is professional, polite, respectful and has great suggestions.

I am about to embark on another project and I did not hesitate to call Four Star.

 Trustindex verifies that the original source of the review is Google. Have used Four Star as an electrician in Wilmington MA multiple times for small electrical issues as well as installation of a Tesla charger. Can't recommend highly enough - work is great / lasts a long time, they take the time to explain issues and options (not just upsell) and clearly have a high level of expertise.
