Can I live in the house during a whole-home rewire?

Almost always, yes. We stage the work room by room and keep power on in the occupied parts of the home overnight. We'll give you a day-by-day schedule of which circuits are dark so you can plan around the fridge, Wi-Fi, and bedrooms.

Is knob-and-tube wiring safe if it hasn't been touched?

Original, undisturbed knob-and-tube in open joist bays can technically be safe - but in practice almost every older DMV home has had insulation blown over it, junction boxes added, or grounded appliances plugged into ungrounded circuits. Once that's happened, the safe answer is to rewire. Most insurers now require it.

Do I have to rewire the whole house at once, or can I do it in phases?

Phased rewires are common - kitchen and primary bath first during a remodel, the rest of the house in a later phase. We'll map out the safest sequence so each phase is code-compliant on its own and the final phase ties cleanly into earlier work.
