Frequently Asked Questions
My Havertown home has flickering lights and nuisance trips with my arc fault breakers. Is this related to knob and tube wiring?
Yes, these are frequent signs of aging or faulty electrical systems common in older Havertown homes. Flickering can indicate loose connections in old wiring, while arc fault breakers are designed to trip when they detect dangerous arcs—often a symptom of deteriorating knob and tube insulation. We specialize in diagnosing these specific local issues and providing safe, code-compliant rewiring solutions that resolve the root cause, ensuring your home's electrical system is both safe and reliable.
What sets your outdoor lighting installation apart for older plaster homes?
Installing outdoor lighting on a plaster home requires a different skill set. We make precision cuts in the plaster to run wiring, minimizing damage to the historic material. All work is done according to NEC code for safety and durability. After installation, we patch any openings with traditional plaster methods—not drywall—to ensure a seamless, breathable repair that matches the original wall and withstands the local climate, protecting your home's beauty and value.
Do you handle the full process for an electrical panel replacement, including plaster repair?
Absolutely. From the initial inspection and safe removal of the old panel to the new installation, we manage the entire project. Understanding that many Havertown homes have plaster walls, we take extra care during the process. We protect your floors, make clean, intentional cuts for access, and—true to our specialty—repair all plaster damage using proper plaster techniques, not shortcuts. We finish with a complete clean-up, leaving your home updated, safe, and looking pristine.
