Great work, great service
Customer Service
Carl came around to the house to replace a number of outdated and tired electrical sockets, and to repair a faulty light fitting. His approach was professional, friendly and efficient, and while here identified other opportunities to bring our house’s electrical supply up to date. We were so impressed, we have lined him up to return and make the improvements very soon. Highly recommended.
