After a power surge fried our old TV, we decided to get professional surge protection installed. The technician from Blackstone explained everything clearly and had the system set up in no time. Now we feel confident knowing our appliances and electronics are protected, especially during storms. It was one of the best home investments we’ve made.

We’ve called Blackstone for everything from ceiling fan installation to fixing faulty outlets, and every time the service has been excellent. The electricians arrive on time, explain what they’re doing, and leave the area spotless. It’s rare to find a company that delivers this level of consistent professionalism.

Our old panel couldn’t keep up with modern appliances, and we were constantly tripping breakers. Blackstone upgraded us to a new electrical panel, and the difference is night and day. Everything runs smoothly now, and I feel safer knowing the system is up to code. Great investment in our home’s future.

I was nervous about the cost and complexity of installing an EV charger, but Blackstone made it stress-free. The technician explained everything clearly, completed the install the same day, and tested it thoroughly. Now I can charge my car overnight without worry. Excellent service!
