The work performed was new main service installation. It involved pulling new service wires, installing a main service panel and a sub-panel in another building. The work was done quickly and professionally. Several days after the work was completed and I had already paid the invoice, I contacted Keith with a concern I had regarding the invoice. He called me back quickly, and resolved my concerns in such a way that I will not hesitate to use him when the house is being built. He goes out of his way to please his customers, and seems to be highly respected by other contractors, service providers, and building inspectors I've spoken to.. 5-stars!
