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.

Do you cover all of Fairfax's ZIP codes?

Yes, we serve 22030 through 22035, including Fairfax City, the Mosaic District area, Fair Oaks, Oakton, and the areas near Burke, Centreville, Vienna, and Annandale.

Why does my 1970s Fairfax townhome keep tripping breakers?

It's often a combination of an aging Federal Pacific or Zinsco panel and aluminum branch wiring that was standard in that era. Both were common in Fairfax County construction from the 1970s and 80s, and both are worth having inspected rather than just replacing the breaker over and over.

Whole-Home Rewiring in Fairfax, VA - Pirro Electric

Fairfax's huge stock of 1970s-80s single-family homes and townhomes in areas like Fair Oaks, Oakton, and neighborhoods near Fairfax City carries a lot of aluminum branch wiring, original Federal Pacific panels, and 100-amp services that are now overloaded by EVs, added HVAC, and home offices. Old Town Fairfax has an older core of homes that mix knob-and-tube remnants with later aluminum-era rewiring, so it's not unusual to find both problems in one house. Commercial stretches along Route 50 and Route 29, plus the Mosaic District area near Merrifield, generate steady tenant fit-out and lighting retrofit work as retail and office space turns over. Fairfax County issues most electrical permits here, with Dominion Energy as the utility for the majority of the county and NOVEC serving parts of western Fairfax, so we confirm which utility applies before scheduling service work. That mix is exactly why Fairfax, Virginia property owners call Pirro Electric for whole-home rewiring.
