Trusted experts for high-quality knob & tube replacement results.






We handle knob & tube replacement for homes and businesses across the Triangle. Knob &. Tube replacement is essential for older homes built before 1950. This outdated wiring lacks a ground wire. It cannot handle modern electrical loads safely. We remove old ceramic insulators and cloth-wrapped wires from your home. Then we install new Romex cable that meets current NEC Article 334 standards. Our electricians fish new 14/2 and 12/2 wire through your walls. We do not tear up your entire home. We pull permits for every job. We coordinate inspections with local building departments. Most insurance companies will not cover homes with active knob and tube wiring. Upgrading protects your investment and your family. We test circuits with digital multimeters. This verifies proper grounding before we restore power. Each room gets updated with properly rated breakers in your panel. You get safer outlets, better capacity, and improved reliability.
Our team maps your existing circuits first. We identify all active knob and tube runs. We check your main panel capacity. This ensures it can handle the updated wiring load. You receive a written estimate. It breaks down costs by room or circuit. No surprises or hidden fees.

PowerMaster Electric has provided us with excellent service on our generator. The technicians, Chris and Asber, were thorough and explained everything to us. Hal came through before a severe ice storm by scheduling Asber to come to our home to install a part necessary to keep our generator running. Valerie in the office is so friendly and patient always following up to make sure our generator is running properly. Highly recommend!Posted on Google michael bullardJanuary 28, 2026Trustindex verifies that the original source of the review is Google. We had a routine annual maintenance visit scheduled and the technician (Abser) identified a failed circuit board controller. He didn't have one on his truck but had to come back the next day (which was with a winter storm barreling down on the area). After a long day on calls out of the area he came by well after dark to replace the board right before the storm arrived. He did an excellent job communicating and updating us on his progress during the day and ETA for the evening. Well done on the customer service to get our generator up and running before the storm.Posted on Google Bkay DoveDecember 17, 2025Trustindex verifies that the original source of the review is Google.
