Pirro Electric handles whole-home rewiring for homeowners, businesses, and property managers in Alexandria, VA. Work is scoped on site, quoted in writing, permitted, and inspected before we call it done. Typical scope: knob-and-tube (k&t) removal and replacement with modern nm cable, cloth- and rubber-insulated wiring replacement, and ungrounded 2-prong outlet conversion to grounded 3-prong circuits.
Old Town Alexandria's 18th- and 19th-century rowhomes often still have surface-mounted knob-and-tube remnants, undersized services, and original fuse panels behind walls that have been renovated multiple times, so any real electrical work there also has to go through the Board of Architectural Review because of the historic district. Del Ray's early-1900s bungalows and Rosemont's older single-family homes have a mix of original wiring and 1960s-era aluminum branch circuits that need remediation.
Signs Your DMV Home Needs a Whole-House Rewire
Most whole-home rewire calls we take in the DMV come from houses built before 1970 - bungalows in Takoma Park, Cape Cods in Silver Spring, ramblers in Bethesda and Arlington, rowhouses in Capitol Hill and Mount Pleasant, and pre-war farmhouses in Frederick and Loudoun County. The patterns are consistent: warm or discolored outlets, breakers that trip when two kitchen appliances run together, scorch marks behind switch plates, lights that dim when the HVAC kicks on, and the smell of burning plastic from a junction box.
Two findings almost always trigger a full rewire conversation: visible knob-and-tube wiring in the attic or basement joists, and a denial or non-renewal letter from a home insurer who inspected the property. Once either of those shows up, patching individual circuits is no longer the right answer - it's time to plan a real rewire.
How a Whole-Home Rewire Actually Works
A rewire is staged room by room, not blown through the whole house at once. We sequence the work - typically kitchen and primary bath first, then bedrooms, then living spaces - so power stays on in occupied parts of the home overnight. Most clients live in the home during the work; we coordinate which circuits are dark on which day so you can plan around the fridge, Wi-Fi, and bedrooms.
In finished homes with plaster or drywall, the goal is to fish new cable through existing wall cavities with the minimum number of access holes - typically one or two small openings per circuit, cut cleanly and left drywall-trade-ready. In gut renovations or homes with open basements and accessible attics, we run new homeruns directly to a new or existing panel.
Most single-family whole-home rewires in the DMV take one to three weeks of on-site work, depending on square footage, wall construction (plaster is slower than drywall), how many circuits exist, and whether the panel and service entrance need to be replaced at the same time.

What Affects the Price of Whole-Home Rewiring in Alexandria
Every quote is written after an on-site look. These are the variables that move the number:
- Square footage and number of stories
- Total circuit count (typical older home: 20–40 circuits)
- Wall construction - accessible (open studs, basement, attic) vs. finished plaster or drywall
- Whether the panel and service entrance need to be replaced at the same time
- Plaster walls (slower fish work, more careful patching) vs. drywall
- Occupied during work vs. vacant
Local Conditions We Work Around in Alexandria
Seminary Hill and Beverley Hills, built mostly in the 1940s-60s, commonly still run on 100-amp services. Eisenhower Valley and Potomac Yard are the newer end of the city, with mid-rise office and residential buildings that need ongoing tenant fit-outs and EV-ready garage wiring. Electrical permits in Alexandria go through the City of Alexandria, and Dominion Energy is the utility for service coordination.
