Whole House Rewiring Cost
What does whole-house rewiring cost in the DMV? Real pricing per square foot, aluminum vs knob-and-tube, and phased scope.
Whole-house rewiring in Maryland, DC, and Northern Virginia typically runs $8–$18 per square foot for occupied homes, $6–$12 per square foot for gut renovations. A 2,000 sq ft home usually falls in the $16,000–$36,000 range depending on access, wall finish, and the number of circuits. Aluminum and knob-and-tube homes fall on the higher end because more devices and junctions must be addressed.

Why price varies so much
Access is 60% of the labor. A home with an unfinished basement and attic can be rewired with minimal drywall repair. A slab-on-grade home with plaster walls and no attic requires cutting, fishing, and patching every wall — that's where the higher-end pricing comes from.
What's included
New service and panel sized for modern load (usually 200A), new copper wiring to every device, arc-fault and ground-fault protection per current code, dedicated circuits for kitchen, laundry, bath, and HVAC, and a labeled panel schedule. Drywall patching is included at rough-in-friendly locations; finish drywall and paint are typically owner or GC scope.
Phased rewiring for occupied homes
If a full rewire isn't budget-friendly today, we phase — kitchen and baths first, then bedrooms, then remaining spaces. Every phase leaves the house code-compliant and safe.
