Q&A
My older Medway home has flickering lights. Could this be from old wiring or rodents?
Yes, both are common issues in our area. Aging wiring in historic homes can degrade and become unsafe, while rodents often chew on wire insulation, especially in attics and crawl spaces. We perform thorough electrical inspections to diagnose the exact cause—whether it's outdated wiring needing replacement or rodent damage requiring repair—and provide a clear, safe solution to protect your home.
Do you handle electric vehicle charging station installations for residential homes?
Absolutely. We offer professional EV charging station installation and repair. Drawing on John's Electrical Engineering background and extensive licensing, we ensure the installation is done correctly, with proper circuit and panel upgrades if needed. We work with you to find the optimal location and setup for convenient, efficient home charging.
What's involved in a standard electrical panel upgrade or repair?
An upgrade or repair typically starts with an inspection of your current panel to assess its capacity and condition. We then handle all aspects, from safely disconnecting the old panel and installing a new, properly rated unit to ensuring all circuits are correctly transferred and labeled. This service is crucial for safety, especially in older homes, and to support modern electrical demands like additional appliances or EV chargers.
