Knob and tube wiring was fine for its era, but that era ended decades ago. It has no ground, the insulation degrades over time, modern attic insulation traps heat against it, and most home insurers now require it to be removed before they will renew a policy. We trace it through the house, replace it section by section with minimal damage, and provide the ESA documentation your insurer asks for. This work often comes up during a larger renovation, so we can fold it into the rest of the project.
Often paired with panel upgrades, rewiring & renovations, and residential electrical. We coordinate the whole job under a single permit when it makes sense.
