I have used Tandem several times to upgrade the electrical service for clients for whom we are doing renovation work. Each time the work has been carried out promptly and properly and I will certainly use Tandem again for other projects. Peter M..renovation contractor.
We contracted Tandem Electric to update our electrical system from Knob & Tube. They did an excellent job and were very professional. As a first time home-buyer, I was very appreciative of their advice and taking the time to answer all my questions. K. Chun
