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.

Yes. Pirro Electric is fully licensed and insured to perform commercial and residential electrical work in Maryland, Virginia, and Washington, D.C., including Rockville. We pull all required permits and coordinate inspections with the local jurisdiction on every job.

Do you handle aluminum wiring remediation in Rockville?

Yes. Aluminum wiring remediation is one of our specialties for multi-unit buildings, condos, and single-family homes built in the late 1960s and 1970s throughout Rockville and the broader DMV. We rewire to copper, replace outdated panels, and document everything for insurance carriers.

Whole-Home Rewiring in Rockville, MD - Pirro Electric

Pirro Electric brings 23 years of Maryland electrical experience to every whole-home rewiring job in Rockville. Rockville's mix of 1960s–70s split-levels and townhomes means many properties still have aluminum branch wiring or original Federal Pacific / Zinsco panels. Newer infill construction along Rockville Pike and around Pike & Rose has driven a wave of EV charger installs and 200-amp service upgrades.

On any given month you'll find our trucks handling 200-amp panel upgrades in 1960s split-levels and aluminum-to-copper rewiring in townhome communities across Fallsmead, College Gardens, Hungerford, and Lincoln Park. We pull permits in Rockville, schedule inspections, and walk you through the work so nothing gets left to guess.
