Reviews

What customers say

Customers describe phone estimates as straightforward or quick and easy, and mention prompt or on-time arrivals. One customer also appreciated an explanation of the planned work and answers to questions. A customer who had an earlier unsatisfactory experience says Foster Electric replaced the whole stove hood it had installed at its own expense and made sure the household was happy with the result.

David Prenshaw

Fantastic group to work with! Estimate was straightforward and they were able to do it over the phone. Scheduling was easy and the team was very prompt and took time explaining what they were going to do and addressed all of my questions and concerns. Highly recommend!

Anna Woods

The whole experience was seamless. The phone quote was quick and easy. The technicians showed up on time and only took an hour to reposition and hang my chandelier. I’m super happy with the result, and would recommend to my family and neighbors.

Sarah Schmid

I'm a FAN of the great work done by David and Walker from Foster Electric! They were trustworthy and kind. Although my project was small, they made sure it was done right so I was happy with the final product.

Alaina N

We have worked with Dillon at Foster Electric twice now. We have had a ceiling fan, wafer lights, bathroom fan/light, garage lights and outlets installed. As new TN residents, we are thankful to find an electrician we can trust, and know the work will be superb. Dillon is friendly, clearly a hard worker, cares about the finished product, is very respectful/professional to customers and we will always ask for him if/when we have any other need for an electrician.

This is an update of a previous review that was not good. I am happy to say that Foster Electric sent out two of their best electricians, (Jason and Dillon), replaced the whole stove hood that they had installed at their own expense, and made sure that my husband and I were happy with the results. They took their time, and were knowledgable and professional. It's great when a business truly stands behind their work. We recommend using Foster Electric.
